Mini radio tags help track ‘murder hornets’ and other invasive insects
- Our increasingly interconnected world is moving insect pests around the planet, introducing invasive species that threaten agriculture and local ecologies.
- But tech is fighting back: Researchers have developed radio-tracking tags small enough to attach to invasive yellow-legged hornets in the U.K. and Europe, allowing scientists to find and destroy their nests.
- Researchers are now deploying this technology in the U.S., to address yellow-legged hornets in Georgia and northern giant hornets in the Pacific Northwest.

The man who made a pact with wild bees in Colombia’s Amazon
- Delio de Jesús Suárez Gómez, a member of the Indigenous Tucano community in Colombia, is combining ancestral knowledge with science to help pollinating bees survive the harsh conditions of life in the rainforest.
- In return, the bees provide honey for families, which is sold, and boosts the communities’ food and fruit supply through pollination.
- The newly-formed group Asomegua (Asociación de Meliponicultores del Guainía) is the result of a decade of beekeeping in La Ceiba, a community on the banks of the Inírida River near the famous Mavicure Hills.
- Bee populations around the world, which participate in the pollination of 75% of the world’s food crops, are on the decline, according to the United Nations Food and Agriculture Organization (FAO).

Community conservation benefits Sulawesi flying foxes, but more is needed, experts say
- Flying foxes play a vital role in maintaining forest health. As pollinators and seed dispersers they are also invaluable to the economic and social well-being of communities.
- In Indonesia’s Sulawesi, conservation groups are working to protect flying foxes, which face threats including hunting for food and habitat loss.
- Community-led approaches are showing success, but conservationists say greater protection and an expansion of projects is needed to protect more bat roosts.

Pollinator declines linked to half million early human deaths annually: Study
- A new modeling study finds that half a million people are currently dying prematurely every year due to global insect pollinator decline because of lack of availability and/or high price of healthy foods such as nuts, legumes, fruits and vegetables.
- Robust epidemiological research has linked higher fruit, vegetable and nut intake to lowered mortality from many major chronic diseases like heart disease, stroke, cancer and diabetes.
- Researchers assessed the problem nationally: Middle-income countries, including Russia, China and India, are among the hardest hit, as are Indonesia, Vietnam and Myanmar, though surprisingly, parts of Latin America and sub-Saharan Africa were among the least affected. Wealthy nations were more immune from pollinator decline.
- Experts say multiple solutions are readily available: Wild pollinators can be significantly increased by protecting existing, and creating new, pollinator habitat at the farm and national level, by reducing and eliminating the use of harmful pesticides like neonicotinoids, and by effectively combating climate change.

Is invasive species management doing more harm than good? (commentary)
- Conservationists may be thwarting their own efforts, as well as causing harm to wildlife, in their battle against invasive species, a new op-ed argues.
- In numerous cases, non-native species have been shown to benefit wildlife, while their management – from toxic chemicals to culling – may be causing more harm than good.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

‘Beenome’ project aims to boost bee conservation with genetic mapping
- Scientists have announced a plan to map the genomes of at least 100 bee species, representing each of the major bee taxonomic groups in the U.S., to help them determine which bees are more vulnerable to climate change and pesticides.
- A recent study found that of 46 U.S. bumblebee species on record, most had been negatively affected by temperature change over the past 120 years, more so than by precipitation and floral resources.
- A recent court ruling in California allows insects to be covered by the state endangered species act, protecting four native bumblebee species and setting a precedent for similar insect protections in other states.
- At the individual level, you can help bees by cultivating bee habitats, avoiding pesticide use, and planting pollinator-friendly plants in your own yard.

California court ruling opens door for protection of insects as endangered species
- A court ruled this week that the California Endangered Species Act (CESA) can apply to invertebrates, including insects.
- This means legal protections will be in place for four native, endangered bumblebee species in California.
- The decision marks the end of a court battle between conservation groups and a consortium of large-scale industrial agricultural interests.
- An estimated 28% of all bumblebees in North America are at risk of extinction, with consequences for ecosystems and crops, as one-third of food production depends on pollinators.

Climate crisis forecasts a fragile future for wildflowers and pollinators
- A first-of-its-kind experimental study has found that climate change reduces the abundance of wildflowers and causes them to produce less nectar and fewer and lighter seeds.
- These changes also impact pollinating insects visiting the flowers: they have to visit more flowers, more frequently, to gather the required food.
- Fewer flowers imply reduced reproductive fitness in plants, as well as fewer food resources for invertebrates that rely on these plants for food, habitat and shelter.
- Overall, climate change may disturb the composition of wildflower species and their pollinators, impacting agricultural crop yields, researchers say.

More trees means healthier bees, new study on air pollution shows
- Scientists analyzed levels of chemical pollutants in native jataí bees across eight landscapes in Brazil’s São Paulo state.
- They found that in landscapes with more vegetation, the bees had fewer pollutants, at lower levels, indicating that the plants act as a filter and protective barrier
- The findings add to the growing scientific evidence about the importance of afforestation in urban areas, including creating ecological corridors to connect separate landscapes.
- Air pollution is the world’s top driver of illness and death from chronic noncommunicable diseases.

Honey bees find food more easily in cities, thanks to abundant urban gardens
- In London, western honey bees travel shorter distances to find their meals in metropolitan areas than in agricultural ones.
- A rich supply of gardens and decorative flowers provides ample nectar close to urban hives.
- Adding native flowers and similar foraging hotspots near open fields would help support bees in intensively farmed areas.

Enhancing biodiversity through the belly: Agroecology comes alive in Chile
- Agroecology, the practice of ecological principles in farming, is coming to life in a corner of Chile through different faces and practices.
- Like individual bees working toward a common, greater goal, practitioners of agroecology tend have a positive multiplication effect in their territory.
- From food producers to beekeepers to chefs, these practitioners show that scaling up agroecology requires deconstructing implicit knowledge hierarchies, a disposition to learning continuously, and sharing through horizontal networks.

Seed dispersal is just as important as pollination (commentary)
- Why does it seem like conservationists only care about pollination, and the creatures like bees that do it?
- Seed dispersal is every bit as important, and to ensure a future with the greatest plant diversity, we should focus effort on conserving the animal groups known for this activity, known as ‘zoochory.’
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Developing nations pay for rich countries’ hunger for healthy, exotic food
- A new study shows that high-income countries place enormous demands on developing countries’ by importing crops that rely heavily on pollinators.
- The researchers apply the principle of Virtual Water, where goods are seen not just as movements of things but also of raw materials and services, in this case of pollinators.
- A growing demand in places like the U.S. and Europe for healthier diets, rich in fruits and beans, is also putting pressure on scarce pollination services.
- Pollination services may be free, but there are hidden costs to maintaining them, and it is communities in developing countries who pay them, the study suggests.

In Japan, scientists look to the past to save the future of grasslands
- Ecologists in Japan recorded several rare and endangered plant species in old grasslands that are not present in younger ones, mirroring findings from other continents that highlight the rich biodiversity of these landscapes.
- Grasslands face growing threats from humans on a global scale, especially land use change like agriculture and urban growth.
- But some human interventions have had a beneficial effect on biodiversity conservation in Japan, such as the maintenance of ski runs, which provide a safe haven for many of the plant species and pollinators that keep grassland ecosystems healthy.
- The study’s lead author says declining interest in skiing among Japanese may threaten the existence of these ancient grasslands.

Canopy beetles and flowering trees rely on each other in the Amazon, study
- A canopy scientist collected 859 species of beetles from the canopy species of a healthy lowland tropical rainforest in southern Venezuela.
- More than 75% of the beetle species collected were found living exclusively on flowering trees — many on trees with small white flowers.
- The results suggest that flowering trees play an important role in maintaining canopy beetle diversity in the Amazon and that these trees are being visited by beetles more than any other insect order, including bees and butterflies.
- To fight the global decline of insects, “researchers and conservationists must understand the ecological connections between insects and their food plants.”

One year on: Insects still in peril as world struggles with global pandemic
- In June 2019, in response to media outcry and alarm over a supposed ongoing global “Insect Apocalypse,” Mongabay published a thorough four-part survey on the state of the world’s insect species and their populations.
- In four, in-depth stories, science writer Jeremy Hance interviewed 24 leading entomologists and other scientists on six continents and working in 12 nations to get their expert views on the rate of insect decline in Europe, the U.S., and especially the tropics, including Latin America, Africa, and Australia.
- Now, 16 months later, Hance reaches out to seven of those scientists to see what’s new. He finds much bad news: butterflies in Ohio declining by 2% per year, 94% of wild bee interactions with native plants lost in New England, and grasshopper abundance falling by 30% in a protected Kansas grassland over 20 years.
- Scientists say such losses aren’t surprising; what’s alarming is our inaction. One researcher concludes: “Real insect conservation would mean conserving large whole ecosystems both from the point source attacks, AND the overall blanket of climate change and six billion more people on the planet than there should be.”

Bubbles, lasers and robo-bees: The blossoming industry of artificial pollination
- Ninety percent of flowering plants require the help of animal pollinators to reproduce, including most of the food crops we eat.
- But massive declines in the populations of bees, the most efficient pollinators around, and the rising cost to farmers of renting them to pollinate their crops, has spurred the growth of the artificial pollination industry.
- The technologies being tested in this field include the delivery of pollen by drones and by laser-guided vehicles and even dispersal via soap bubbles.
- Proponents of artificial pollination say it can both fill the gap left by the declining number of natural pollinators and help in the conservation of these species; but others say there may not be a need for this technology if there was a greater focus on conservation.

In a Colombian wetland, oil woes deepen with the arrival of fracking
- The wetlands around the Colombian city of Barrancabermeja have for a long time been battered by pollution, including from the region’s oil industry.
- Fishermen say the century of oil extraction here has failed to yield the promised social and economic dividends, while compromising local water resources.
- State oil company Ecopetrol now plans to carry out fracking in a series of pilot projects here, but many communities are skeptical that it will be done responsibly.

US economy will take biggest hit if we continue with business as usual: report
- New research finds that if humans carry on with business as usual and the environmental degradation that results, we will pay a steep price — quite literally.
- Researchers found that if we simply continue under the status quo, the global economy will lose at least $479 billion a year, adding up to nearly $10 trillion in losses by 2050, as compared to the “baseline” scenario in which there is no change in ecosystem services over the next 30 years.
- Of the 140 countries included in the study, the United States stands to take the biggest economic hit, losing $83 billion per year by 2050 under this “business as usual” scenario that includes intense consumption of energy and raw materials, widespread land-use change, ongoing rises in greenhouse gas emissions, and continued loss of biodiversity.

Mongabay investigative series helps confirm global insect decline
- In a newly published four-part series, Mongabay takes a deep dive into the science behind the so-called “Insect Apocalypse,” recently reported in the mainstream media.
- To create the series, Mongabay interviewed 24 entomologists and other scientists on six continents and working in 12 nations, producing what is possibly the most in-depth reporting published to date by any news media outlet on the looming insect abundance crisis.
- While major peer-reviewed studies are few (with evidence resting primarily so far on findings in Germany and Puerto Rico), there is near consensus among the two dozen researchers surveyed: Insects are likely in serious global decline.
- The series is in four parts: an introduction and critical review of existing peer-reviewed data; a look at temperate insect declines; a survey of tropical declines; and solutions to the problem. Researchers agree: Conserving insects — imperative to preserving the world’s ecosystem services — is vital to humanity.

The Great Insect Dying: How to save insects and ourselves
- The entomologists interviewed for this Mongabay series agreed on three major causes for the ongoing and escalating collapse of global insect populations: habitat loss (especially due to agribusiness expansion), climate change and pesticide use. Some added a fourth cause: human overpopulation.
- Solutions to these problems exist, most agreed, but political commitment, major institutional funding and a large-scale vision are lacking. To combat habitat loss, researchers urge preservation of biodiversity hotspots such as primary rainforest, regeneration of damaged ecosystems, and nature-friendly agriculture.
- Combatting climate change, scientists agree, requires deep carbon emission cuts along with the establishment of secure, very large conserved areas and corridors encompassing a wide variety of temperate and tropical ecosystems, sometimes designed with preserving specific insect populations in mind.
- Pesticide use solutions include bans of some toxins and pesticide seed coatings, the education of farmers by scientists rather than by pesticide companies, and importantly, a rethinking of agribusiness practices. The Netherlands’ Delta Plan for Biodiversity Recovery includes some of these elements.

The Great Insect Dying: The tropics in trouble and some hope
- Insect species are most diverse in the tropics, but are largely unresearched, with many species not described by science. But entomologists believe abundance is being impacted by climate change, habitat destruction and the introduction of industrial agribusiness with its heavy pesticide use.
- A 2018 repeat of a 1976 study in Puerto Rico, which measured the total biomass of a rainforest’s arthropods, found that in the intervening decades populations collapsed. Sticky traps caught up to 60-fold fewer insects than 37 years prior, while ground netting caught 8 times fewer insects than in 1976.
- The same researchers also looked at insect abundance in a tropical forest in Western Mexico. There, biomass abundance fell eightfold in sticky traps from 1981 to 2014. Researchers from Southeast Asia, Australia, Oceania and Africa all expressed concern to Mongabay over possible insect abundance declines.
- In response to feared tropical declines, new insect surveys are being launched, including the Arthropod Initiative and Global Malaise Trap Program. But all of these new initiatives suffer the same dire problem: a dearth of funding and lack of interest from foundations, conservation groups and governments.

The Great Insect Dying: Vanishing act in Europe and North America
- Though arthropods make up most of the species on Earth, and much of the planet’s biomass, they are significantly understudied compared to mammals, plants, birds, amphibians, reptiles and fish. Lack of baseline data makes insect abundance decline difficult to assess.
- Insects in the temperate EU and U.S. are the world’s best studied, so it is here that scientists expect to detect precipitous declines first. A groundbreaking study published in October 2017 found that flying insects in 63 protected areas in Germany had declined by 75 percent in just 25 years.
- The UK Butterfly Monitoring Scheme has a 43-year butterfly record, and over that time two-thirds of the nations’ species have decreased. Another recent paper found an 84 percent decline in butterflies in the Netherlands from 1890 to 2017. Still, EU researchers say far more data points are needed.
- Neither the U.S. or Canada have conducted an in-depth study similar to that in Germany. But entomologists agree that major abundance declines are likely underway, and many are planning studies to detect population drops. Contributors to decline are climate change, pesticides and ecosystem destruction.

The Great Insect Dying: A global look at a deepening crisis
- Recent studies from Germany and Puerto Rico, and a global meta-study, all point to a serious, dramatic decline in insect abundance. Plummeting insect populations could deeply impact ecosystems and human civilization, as these tiny creatures form the base of the food chain, pollinate, dispose of waste, and enliven soils.
- However, limited baseline data makes it difficult for scientists to say with certainty just how deep the crisis may be, though anecdotal evidence is strong. To that end, Mongabay is launching a four-part series — likely the most in-depth, nuanced look at insect decline yet published by any media outlet.
- Mongabay interviewed 24 entomologists and researchers on six continents working in over a dozen nations to determine what we know regarding the “great insect dying,” including an overview article, and an in-depth story looking at temperate insects in the U.S. and the European Union — the best studied for their abundance.
- We also utilize Mongabay’s position as a leader in tropical reporting to focus solely on insect declines in the tropics and subtropics, where lack of baseline data is causing scientists to rush to create new, urgently needed survey study projects. The final story looks at what we can do to curb and reverse the loss of insect abundance.

Grasshoppers: They come, they eat, they … pollinate?
- A new paper describes 41 species of orthopterans — grasshoppers, crickets and katydids — visiting flowers, making them potential pollinators.
- More research is needed to understand what role these insects, often viewed as crop destroyers, play in pollination.
- Insects worldwide are in crisis due to pesticide use, loss of habitat and climate change.

House of the Royal Lady Bee: Maya revive native bees and ancient beekeeping
- Melipona beecheii, called Xunan-Kab in the Yucatec Maya language, is one of 16 stingless bee species native to the rainforests of the Yucatán Peninsula in southern Mexico.
- Xunan-Kab, like other stingless bees, is a prolific rainforest pollinator critical to the local ecosystem, but deforestation is gravely impacting wild populations.
- Local beekeepers have kept domesticated colonies of Xunan-Kab for at least 3,000 years, but the practice declined strikingly in recent decades.
- Today, however, traditional Xunan-Kab husbandry is experiencing a modest revival, offering hope for Mayan communities and rainforests of the Yucatán Peninsula.

Cities could help conserve pollinator communities
- While cities are generally considered to be poorer in biodiversity than rural areas, new research finds that urban areas could actually play a key role in conserving pollinator communities.
- A team of researchers led by scientists at the UK’s University of Bristol studied pollinators and floral resources at 360 sites in four British cities representing all major urban land uses, including allotments (community gardens), cemeteries, gardens, man-made surfaces like parking lots, nature reserves and other green spaces, parks, sidewalks, and road verges.
- After sampling 4,996 insects and documenting 347 flower-visiting pollinator species interacting with 326 plant species, the researchers found that gardens and allotments provide especially good habitat for pollinators, and that lavender, borage, dandelions, thistles, brambles, and buttercups are important plant species for pollinator communities in cities.

Latam Eco Review: Whale attacks, palm oil woes, and hope for vaquitas

Peruvian palm oil, orca attacks on humpback whales, and mining in an Amazon national park are among the recent top stories from Mongabay Latam, our Spanish-language service. Orcas attack young humpbacks migrating north For 30 years, Juan Capella and five other researchers analyzed thousands of photos of humpback whales (Megaptera novaeangliae) off Panama, Colombia, Ecuador, […]
Pesticides banned by EU for their potential harm to bees
- The EU will ban three commonly used pesticides by the end of 2018 in a bid to protect bee populations.
- A committee passed the measure with a majority vote after research emerged earlier this year demonstrating that each compound posed a threat to wild bees and honeybees (Apis mellifera), whose pollination services are critical for crop production.
- Environmental and consumer groups applauded the decision.
- But several groups representing farmers voiced concerns about how effectively the measure would improve bee health, as well as the difficulty its passage posed to farmers who depend on using these pesticides.

Light pollution lures nighttime pollinators away from plants
- Over the last two decades, nighttime light emissions in North America and Europe have increased by more than 70 percent.
- This artificial light lures moths and other insect pollinators away from plants, a new study shows.
- This effect may also make daytime pollinators less efficient, posing a further threat to plants and global food security.

Conservation leaders in Africa call for a crackdown on biopiracy
- Indigenous rights groups and others have long criticized the lack of benefit sharing between bio-prospectors and the local communities that inhabit the places where the organisms are found, calling such acts “biopiracy.”
- The African Union (AU) Strategic Guidelines for the Coordinated Implementation of the Nagoya Protocol in Africa was adopted by the AU Assembly at its 25th Ordinary Session, which was held in South Africa in 2015. The guidelines aim to provide a roadmap for implementation of the Protocol and Access and Benefit Sharing system at national and regional levels.
- But while the Nagoya Protocol and its AU implementation guidelines address many issues, some stakeholders remain worried about those not covered – such as off-site synthesis using information previously collected and the use of materials cultivated abroad.

Bats key pollinators for durian production, camera traps confirm
- A new study employing camera traps indicates that flying foxes in Malaysia are important pollinators of commercially valuable durian fruit trees.
- The researchers set 19 traps in semi-wild durian trees.
- Their investigation revealed that the bats had a positive impact on the transformation of the flower to fruit.

Trump administration delays listing of rusty patched bumblebee as endangered
- In January, 2017, the US FWS declared that it was placing the rusty patched bumblebee on the U.S. endangered species list.
- The listing would have taken effect today, making it the first wild bee species to be declared endangered in the continental US.
- But the USFWS has tentatively postponed the bee’s listing from February 10 to March 21.

Rusty patched bumblebee now first bee to be listed as endangered in continental U.S.
- The U.S. Fish and Wildlife Service (FWS) announced the endangered designation on Tuesday.
- The final rule listing the rusty patched bumblebee as endangered appeared in the Federal Register the following day and will take effect on February 10.
- According to FWS Midwest Regional Director Tom Melius, the bumblebee is among a group of pollinators, which also includes the monarch butterfly, whose populations have declined sharply across the country.

China’s reforestation program a letdown for wildlife, study finds
- According to fieldwork from south-central Sichuan Province, biodiversity within monocultures is lower than within cropland, the very land being restored.
- The research found that cropland restored with mixed forests offers marginal biodiversity gains and comes at no economic cost to households, relative to monocultures.
- The researchers recommend incentives for restoration of native forests under the program, which they say would provide the greatest benefits for biodiversity.

Rising CO2 is reducing nutritional value of food, impacting ecosystems
- As CO2 levels rise, so do carbohydrates in plants, increasing food’s sugar content. While carbon-enriched plants grow bigger, scientists are finding that they contain proportionately less protein and nutrients such as zinc, magnesium and calcium.
- A meta-analysis of 7,761 observations of 130 plant species found that overall mineral concentrations in plants declined by about 8 percent in response to elevated CO2 levels — 25 minerals decreased, including iron, zinc, potassium and magnesium.
- New research found that as atmospheric CO2 rose from preindustrial to near current levels, the protein content in goldenrod pollen fell by 30 percent. Bees and other pollinators rely heavily on goldenrod as protein-rich food for overwintering. The loss of pollinators could devastate many of the world’s food crops.
- Research into the correlation between CO2 concentrations and the nutrient content of food is in its early stages. More study is urgently needed to determine how crops and ecosystems will be altered as fossil fuels are burned, plus mitigation strategies.

The week in environmental news – Feb 26, 2016
- A report sponsored by the U.N. pulled from approximately 3,000 scientific papers and revealed that 40 percent of invertebrate pollinator species are facing extinction.
- The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is working toward improving the treatment of the animals that are caught and sold around the globe.
- In order to protect biodiversity from salt pollution of freshwater, scientists are calling for a global change in the way we regulate the salinity of freshwater sources.

Creating wild edges on fields boosts wildlife numbers and crop yield
- Researchers investigated the value of creating wildlife-friendly habitat on low-yielding edges of fields that have been removed from food production.
- Creating such wildlife-friendly habitat seemed to boost overall crop yield, and wildlife numbers, study found.
- In fields with habitat edges, crop yield increased over time, researchers found.

Curb climate change or lose bumblebees, blueberries, tomatoes

According to a comprehensive new study published in the journal Science, bumblebees are particularly vulnerable to climate change disruptions. Historical bumblebee ranges have shrunk on their extreme southern edge, while species to the north fail to adapt with any significant migration into cooler regions. “Climate change appears to contribute, distinctively, and consistently, to… range compression […]

Pollinators puzzle to find flowers amidst natural and human fumes

While unpleasant car exhaust makes us wrinkle our noses, such human-made fumes may pose serious problems to insects searching for nectar. Researchers recently revealed that background odors make finding flowers difficult for pollinators. The study, published in Science, measured how hawk moths (Manduca sexta) pick out the sacred datura flower scent (Datura wrightii) amidst all […]
‘Stop using the bloody things’: pesticides linked to bee collapse now blamed for bird declines

In recent years the evidence has piled up that neonicotinoids—a hugely popular group of pesticide—may be at least partly responsible for ongoing bee and pollinator collapse. But new research in the journal Nature find that these pesticides could also be taking a heavy toll on other species, in this case common birds. Using longterm data […]
More is better: high bee biodiversity boosts crop yields

Scientists have discovered that blueberry plants visited by more diverse bee species increased their seed number, berry size and fruit set, and quickened their ripening time. They hope their findings encourage farmers to help support local wild bee communities. Led by Dr. Shelley Rogers, researchers from North Carolina State University in the U.S. studied a […]

Florida declares two butterfly species extinct as pollinator crisis worsens

Conservationist’s faced a crushing blow last month as two butterfly species native to Florida were declared extinct. “Occasionally, these types of butterflies disappear for long periods of time but are rediscovered in another location,” said Larry Williams, U.S. Fish and Wildlife state supervisor for ecological services. We think it’s apparent now these two species are […]
Habitat loss and pesticides causing decline in Europe’s butterflies

Europe’s grassland butterfly population has plummeted in the past two decades, new research published on Tuesday shows, with a near halving in the numbers of key species since 1990. The precipitous decline has been blamed on poor agricultural practices and pesticides, by the European Environment Agency, which carried out the research. Falling numbers of butterflies […]
Losing just one pollinator species leads to big plant declines

A shocking new study finds that losing just one pollinator species could lead to major declines in plant productivity, a finding that has broad implications for biodiversity conservation. Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are […]
EU labels another pesticide as bad for bees

A widely used insect nerve agent has been labelled a “high acute risk” to honeybees by the European Food Safety Authority (EFSA). A similar assessment by the EFSA on three other insecticides preceded the suspension of their use in the European Union. “The insecticide fipronil poses a high acute risk to honeybees when used as […]
U.S. loses nearly a third of its honey bees this season

Nearly a third of managed honeybee colonies in America died out or disappeared over the winter, an annual survey found on Wednesday. The decline—which was far worse than the winter before—threatens the survival of some bee colonies. The heavy losses of pollinators also threatens the country’s food supply, researchers said. The US Department of Agriculture […]
Europe bans pesticides linked to bee collapse

The EU has banned three neonicotinoid pesticides (imidacloprid, clothianidin and thiamethoxam) linked to the decline of bees for two years. The ban will apply to all flowering crops, such as corn, rape seed, and sunflowers. The move follows a flood of recent studies, some high-profile, that have linked neonicotinoid pesticides, which employ nicotine-like chemicals, to […]
Domesticated bees do not replace declining wild insects as agricultural pollinators

Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may […]

After damning research, France proposes banning pesticide linked to bee collapse

Following research linking neonicotinoid pesticides to the decline in bee populations, France has announced it plans to ban Cruiser OSR, an insecticide produced by Sygenta. Recent studies, including one in France, have shown that neonicotinoid pesticides likely hurt bees’ ability to navigate, potentially devastating hives. France has said it will give Sygenta two weeks to […]

What does Nature give us? A special Earth Day article
- Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit.
- The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled.
