(Beyond Pesticides, February 11, 2014) In the midst of another tough winter for bees across the globe, scientists reveal new research showing that exposure to neonicotinoid pesticides causes a 57% reduction in the amount of pollen bumblebees are able to collect for their colony. The new evidence on these systemic pesticides, “Field realistic doses of pesticide imidacloprid reduce bumblebee pollen foraging efficiency,” published in the journal Ecotoxicology, documents a decline in pollen gathering abilities at extremely low doses that bees are likely to encounter in the field. Researchers found that the effects of neonicotinoid intoxication persist for a least a month after exposure, underscoring the long-term damage these chemicals can cause to bee colonies. Hannah Feltham, PhD, research student and co-author of the study, remarked, “This work adds another piece to the jigsaw. Even near-infinitesimal doses of these neurotoxins seem to be enough to mess up the ability of bees to gather food. Given the vital importance of bumblebees as pollinators, this is surely a cause for concern.” After being exposed to “near-infinitesimal” amounts of the neonicotinoid imidacloprid through pollen and sugar water (6 parts per billion and .7 parts per billion, respectively), bumblebees were outfitted with Radio Frequency Identification […]

(Beyond Pesticides, February 7, 2014) Flying in the face of  recent science demonstrating that pollinator populations are declining, the U.S. Environmental Protection Agency (EPA) has made the decision to unconditionally register another pesticide that is known to be highly toxic to bees, coming almost one year after EPA registered sulfoxaflor, disregarding concerns from beekeepers and environmental groups. The announcement, posted in the Federal Register on Wednesday, set tolerances for the pesticide cyantraniliprole in foods ranging from almonds and berries, to leafy vegetables, onions, and milk. EPA establishes the allowable limit of the chemical residue, called tolerances, based on what EPA considers ”˜acceptable’ risk.  EPA’s ruling details that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide residue,” despite all evidence that cyantraniliprole is toxic to bees and harmful to mammals. Ignoring beekeeper warning and concerns on their impacts to bees, EPA has given the green light for cyantraniliprole after recently registering sulfoxaflor.  In July 2013, beekeepers filed suit against EPA for their decision to register sulfoxaflor when it failed to demonstrate that it will not cause any ”˜unreasonable adverse effects on the environment’ as required by the Federal Insecticide, Fungicide, and Rodenticide Act […]

(Beyond Pesticides, January 21, 2013) Two Minnesota state agencies are creating plans they say will  address declining pollinator populations in the state. The Minnesota Department of Natural Resources (DNR) is developing best management practices for managing and increasing pollinator habitat and the Minnesota Department of Agriculture (MDA) is developing a plan to study the impacts of neonicotinoid pesticides on pollinators. Critics of the state’s plan say that there is no more need to study the effects of neonicotinoids because the negative impacts they have on pollinators has been already studied extensively.   The DNR is developing guidelines to improve habitat for pollinator insects. Recent reports show that  the planting of herbicide-resistant genetically engineered (GE) crops is responsible for habitat loss and the decline of native pollinators like the Monarch butterfly. The expansion of glyphosate tolerant GE corn and soybean cropland has allowed farmers to kill milkweed, the primary source of food for Monarchs, which historically grew between crop rows in the Midwest. A rapid expansion of farmland ””more than 25 million new acres in the U.S. since 2007”” has also eaten away grasslands and conservation reserves that supplied the Monarchs with milkweed. DNR officials have indicated this guide could change […]

(Beyond Pesticides, January 7, 2014) An Oregon state representative, Rep. Jeff Reardon (D-Portland), plans to introduce legislation in February that will effectively ban for home and garden use  certain neonicotinoid pesticides implicated in mass bee deaths this  summer. This legislation is part of the growing national effort to ban or restrict the use of neonicotinoid pesticides. Last year, the Save America’s Pollinators Act was introduced by Representative Earl Blumenauer (D-OR) to ban the use of neonicotinoids nationally. Rep. Reardon’s legislation would add neonicotinoid pesticides dinotefuran, imidacloprid, clothianidin and thiamethoxam to Oregon’s restricted pesticide use list. Under Oregon’s pesticide administrative rules,restricted use pesticides can only be applied by licensed pesticide applicators. Pesticide dealers are also required  to keep records of product sales of these pesticides and maintain sales records for at least three years. The legislation would also require the state to implement special training and testing to ensure licensed pesticide applicators know how to minimize risk to   pollinators. “These are dangerous chemicals. People who aren’t willing to take the time and effort to become fully educated should look for alternatives,” Rep. Reardon told The Oregonian. Though this legislation would limit the amount of neonicotinoid pesticides directly applied to lawns […]

(Beyond Pesticides, December 20, 2013) The European Food Safety Authority (EFSA) announced on Tuesday that pesticides linked to honey bee deaths worldwide may also damage human nervous systems ””in particular the brain, and recommended that the European Commission lower the guidance levels of acceptable exposure until more research is conducted. This new determination heightens the call to ban the use of these toxic chemicals in the U.S., following the lead of the European Union (EU). EFSA found that two commonly used chemicals “may adversely affect the development of neurons and brain structure associated with functions such as learning and memory” particularly of children. The recommendation focuses on two chemicals ””acetamiprid and imidacloprid”” in a relatively new class of insecticide called neonicotinoids. Three chemicals in this class were recently placed under a two-year ban in the European Union (EU) for uses on flowering crops known to attract honey bees. The move stems from a recent review of research on rats which found, “Neonicotinoids may adversely affect human health, especially the developing brain.” Researchers who exposed newborn rats to one of these chemicals ””imidacloprid”” found they suffered brain shrinkage, fewer nerve signals controlling movement, and weight loss. Another study on rats found […]

(Beyond Pesticides, December 19, 2013) Environmental and farm groups, including Beyond Pesticides,  came together to file a legal brief in support of the nation’s major beekeeping associations’ lawsuit against the U.S. Environmental Protection Agency (EPA). The beekeepers, including the Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, and the American Beekeeping Federation, are requesting that a federal court vacate EPA’s decision to register sulfoxaflor, a new chemical known to be highly toxic to bees and considered in the same chemical class of the controversial insecticides known as neonicotinoids, which have been linked to bee decline. According to the  Friend of the Court (Amicus curiae) brief, filed by the Center for Food Safety on behalf of the organizations, “Scientists have linked the drastic declines in honey bee and other pollinator populations to systemic pesticides, and more specifically, to a category of systemic pesticides known as neonicotinoids.  Sulfoxaflor is a systemic pesticide with the same mode of action as neonicotinoids, that EPA determined is ”˜very highly toxic’ to bees.  EPA’s registration of sulfoxaflor will introduce yet another systemic and highly toxic insecticide into the environment, intensifying the ecological crises of Colony Collapse Disorder (CCD) and other pollinator losses.” […]

(Beyond Pesticides, December 3, 2013) On Sunday, December 1, 2013 the European Union (EU) took critical steps to protect pollinators from the hazards associated with the use of neonicotinoid pesticides. Despite attempts by agrichemical corporations, including Bayer, and Syngenta,   to delay or reverse the decision, the two-year, continent-wide ban on bee-harming pesticides has gone into effect. However, what’s happening on the other side of the Atlantic is part of a larger story that raises serious concerns for the future of our food. In the United States, the Environmental Protection Agency (EPA), under the direction of Administrator Gina McCarthy, has put forth inadequate label changes that do not protect pollinators. With the support of   over 60 organizations, Beyond Pesticides has helped launch a coalition-based  national advertising campaign to raise awareness of pollinator declines and urge EPA to stop stalling by enacting substantive restrictions on the use of bee-harming pesticides. Go to save-bees.org to lend your support to these efforts. Neonicotinoids, a relatively new class of pesticides, are often used as a seed coating on agricultural crops. Studies have found that honey bees are exposed to high concentrations of neonicotioid pesticides through the dust that is kicked up when coated […]

(Beyond Pesticides, December 2, 2013) Today, Beyond Pesticides, Center for Food Safety and Pesticide Action Network, supported by Ceres Trust and joined by more than 60 other organizations, launched a national media campaign to bring attention to the severity of pollinator declines due in part to the use of bee-harming pesticides. The campaign launch was timed to coincide with the beginning of the European Union’s two-year moratorium on three of the most potent neonicotinoids, which began yesterday. See the ad here. For action item related to this campaign, go to www.save-bees.org. For more on Beyond Pesticides’ BEE Protective campaign, go to www.BEEprotective.org. As part of the national media campaign, full page ads were released in seven newspapers today, including the New York Times, citing the urgency and impact of bee declines and encouraging the public to call on EPA to take action. “We hope this national media campaign will spur public action to combat this major threat to the environment and to our food system. We must protect bees and other pollinators from these harmful pesticides that EPA has so far failed to safeguard them from,” said Larissa Walker, policy and campaign coordinator for Center for Food Safety. Never before […]

(Beyond Pesticides, November 25, 2013) The Oregon Department of Agriculture (ODA) has restricted two pesticide products linked to massive bee die offs experienced in Oregon earlier this year. Both pesticides are neonicotinoid chemicals that are extremely harmful to bees. Though these restrictions are an important step in protecting bee health, the new rules will still not limit all of the uses of these chemicals that can harm pollinators. ODA placed restrictions on dinotefuran and imidacloprid, banning their use  on linden trees, basswood and other trees of the Tilia genus. Pesticide products that contain these active ingredients are now required to have Oregon-specific labels. This is only the second time in the past ten years that ODA has regulated pesticides more strictly than federal standards. These new restriction comes after ODA adopted a temporary rule in June that limited the use of 18 pesticide products that contained diontefuran. That rule was set to expire next month. States and local jurisdictions  have authority under the nation’s pesticide registration law, the  Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), to adopt more stringent pesticide use restrictions than the federal government. However, after the U.S.  Congress rejected proposals to preempt local authority and the Supreme […]

(Beyond Pesticides, November 12, 2013) On November 6 BASF, a German agrochemical company, took legal action in the General Court of the European Union (EU) to challenge the EU Commission’s decision to restrict seed treatment uses of the insecticide fipronil. BASF joins chemical companies Bayer and Syngenta in challenging the EU’s decision to restrict the use of certain pesticides that are harmful to pollinators. The EU Commission’s decision to restrict the use of fipronil in July came after the Commission’s landmark decision announcing a two-year continent-wide ban  on the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam. The pesticides have been linked to the decline in bee populations.  Twenty-three European Union Member States supported the fipronil restriction, two Member States voted against, and three Member States abstained during the standing committee vote. BASF argued that its  legal action against the EU is based on a disproportionate application of the precautionary principle. However, overwhelming scientific evidence supports the position that fipronil is highly toxic to bees. Fipronil, a phenyl pyrazole broad-spectrum insecticide, was first introduced in the U.S. in 1996 for commercial turf and indoor pest control and is highly toxic to bees. A recent investigation reveals that fipronil is responsible for the […]

(Beyond Pesticides, October 21, 2013) A study conducted by Sussex University researchers has identified the garden plants most attractive to  pollinating insects. The study’s findings are important as pollinating insects are declining globally and are facing growing habitat losses. The study also gives vital scientific information to individuals and communities on plants that are most beneficial to pollinators. Although creating pollinator friendly habits is an important step to slowing pollinator population decline, environmental groups and activists are focused on addressing the underlying problem that leads to pollinator population loss: the continuous use of toxic pesticides. The study, Quantifying variation among garden plants in attractiveness to bees and other flower-visiting insects, published in Functional Ecology,  collected data over two summers by counting flower-visiting pollinators on 32 popular garden plant varieties to determine which varieties are more attractive to pollinators. The study found that the most attractive flowers are 100 times more attractive than the least attractive flowers. According to the study, the most attractive flowers are borage, lavender, marjoram, and open-flower dahlias. Majoram was the best all-round flower, attracting honey bees, bumble bees, other bees, hover flies, and butterflies. While information on pollinator friendly flowers is widely available, this study was […]

(Beyond Pesticides, October 8, 2013) Stress brought about by chronic exposure to sublethal levels of neonicotinoid pesticides causes bee colony failure, according to a new study published in the journal Ecology Letters. Scientists at Royal Holloway University of London have determined that low-level exposure to the pesticide imidacloprid at levels bees encounter in the field causes subtle impacts on individual bees that eventually cause colonies to collapse. This breakthrough study underlines repeated U.S. beekeeper and environmental group calls  for the Environmental Protection Agency (EPA) to  suspend the use of neonicotinoid pesticides, as the European Commission recently decided this past April. Since 2006, honey bees and other pollinators in the U.S. and throughout the world have incurred ongoing and rapid population declines from hive abandonment and bee die-off in a phenomenon known as colony collapse disorder (CCD). Studies continue to link a class of systemic pesticides called neonicotinoids to the CCD phenomenon and pollinator decline in general. While scientists have cited multiple chemical and other factors that contribute to degrading bee health, until now no study has shown the internal mechanism within bee colonies that causes collapse. By focusing on chronic sublethal stressors, Royal Holloway researchers have addressed the complexities that […]

(Beyond Pesticides, October 4, 2013)  It was hoped that a  recent meeting in Florida between beekeepers and citrus growers could create stronger communication between both agricultural sectors. Beekeepers in Florida have begun to voice growing concerns over the increased use of insecticides on citrus trees where their bees are used as pollinators. Though this meeting worked to set up an important dialog between beekeepers and citrus growers, it focused predominantly on the effects of accidental exposure. This focus does not take into account the long-term residues these systemic insecticides can leave in the environment, contaminating nectar and pollen.     The recent September meeting that was organized by the Florida Agriculture Commissioner Adam Putman, a former U.S. congressman and citrus farmer, was meant to start a dialog between citrus growers and beekeepers. This dialog was viewed as necessary by Florida’s Department of Agriculture as beekeepers are worried over the increased use of insecticides in citrus groves. Recently, citrus farmers have increased their use of insecticides from several times a year to applications every month or greater to combat the invasive Asian citrus pysllids. Asian citrus pysllids can infect trees with a bacterium that causes citrus greening. Honey bees in Florida […]

(Beyond Pesticides, October 2, 2013) New research reveals that Costa Rica’s iconic spectacled caiman crocodiles are under threat from pesticides used on the country’s massive banana plantations. Nearly two million tons of bananas are shipped out of the small South American country each year, and exports are rising alongside with the use of hazardous pesticides. Both past and present use of agricultural chemicals has caused significant impacts on the health of the spectacled caiman, according to scientists from the study published in the journal Environmental Toxicology and Chemistry. Researchers found that the pesticide burden on the caiman increases as they move closer to banana plantations. “The animals are very, very thin””about 50 percent thinner than those away from the plantations,” said study co-author Peter Ross, Ph.D, an aquatic ecotoxicologist and associate professor at the University of Victoria in British Columbia. The scientists note that it is unclear whether the toxic effects of the pesticides are hurting the caiman’s health, or whether the chemicals have caused a more systemic problem, knocking out the prey on which the animals depend. Whatever the case may be, results of the study show that high-trophic level species are being adversely affected by the use of […]

(Beyond Pesticides, September 17, 2013) Last Friday, Health Canada released new measures the agency claims are intended to protect bees from exposure to neonicotinoid pesticides. As with recent regulations proposed by the U.S. Environmental Protection Agency (EPA), beekeepers and environmental groups are criticizing the measures as inadequate, not going far enough to protect domesticated honey bees that both in Canada and the U.S.  have seen losses of over 30% each winter since 2006. Ontario beekeeper Dave Schuit told the CBC, “Basically I see it as a Band-Aid. [The Pest Management Regulatory Agency] should’ve done their study before they approved this pesticide.” Dave Schuit owns Saugeen Country Honey Inc., and reportedly lost 37 million bees last year — more than half of his over 2,000 hives — as a result of exposure to neonicotinoid pesticides. Health Canada’s proposal includes: Requiring the use of safer dust-reducing seed flow lubricants (most corn and soy seed is coated with neonicotinod pesticides before planting and then mixed with a lubricant like talc that creates a toxic  dust in seed planters); Requiring adherence to safer seed planting practices; Requiring new pesticide and seed package labels with enhanced warnings; and Requiring updated value information be provided to […]

(Beyond Pesticides, September 5, 2013) One of Florida’s largest citrus growers, Ben Hill Griffin, Inc., has been fined a mere $1,500 after a state investigation found that the farm illegally sprayed pesticides, resulting in the death of millions of managed honey bees. Beekeeper Randall Foti, a Crystal River-based beekeeper of 42 years, reported the bee kill to the state back in March. According to Mr. Roti, millions of his bees, as well as those owned by beekeeper Barry Hart of Fargo, GA, were dead as a result of over a dozen aerial pesticide sprayings in the orange groves. He estimates that due to the bee kills, his colonies were only able to produce half the amount of honey, resulting in a loss of $240,000 from honey alone. ”Every four days, they were spraying seven or eight different types of chemicals,” Mr. Foti told the Palm Beach Post.  “A $1,500 fine is not much of a deterrent.” Though this is the first time the state of Florida has taken action against a citrus grower for a reported bee kill in relation to a pesticide violation, the Palm Beach Post reports that beekeepers have been arguing for this type of action since […]

(Beyond Pesticides, August 28, 2013) Industry giant, Syngenta, has filed a legal challenge to the European Union’s suspension of one of its insecticides, thiamethoxam, linked to the decline in bee populations that has been observed in Europe and the rest of the world. Thiamethoxam, a neonicotinoid and active ingredient in Syngenta’s Cruiser seed treatments, is widely used to treat seed and degrades into another neonicotinoid, clothianidin, also subject to a moratorium in the  European Union. Both chemicals are cited in a lawsuit seeking their suspension, which was brought by beekeepers and environmental groups in the U.S. Earlier this year, the European Commission made a landmark decision announcing a two-year continent-wide ban on the neonicotinoid pesticides: clothianidin, imidacloprid and thiamethoxam. The decision came in response to a scientific report by the European Food Safety Authority (EFSA) that identified “high acute risk” to honey bees from uses of the neonicotinoid chemicals. Thiamethoxam, as well as clothianidin, are routinely used to treat seeds, especially for major crops like corn. A  15 member states majority  supported the ban, with eight against, and four abstaining. However, in its press release, Syngenta claims that the European Commission made its  decision on the basis of a flawed […]

(Beyond Pesticides, August 19, 2013) The U.S. Environmental Protection Agency’s (EPA) new pesticide label for honey bee protection, announced Thursday, has been widely criticized by beekeepers and environmentalists as offering inadequate protection in the face of devastating bee decline. Under the new guidelines, the label will prohibit the use of some neonicotinoid pesticides when bees are present, and includes a “bee advisory box” and icon with information on routes of exposure and spray drift precautions. Critics question the efficacy of the label change in curtailing a systemic pesticide that contaminates nectar and pollen, poisoning bees indiscriminately, and the enforceability of the label language, which is geared to managed not wild bees. EPA has not formally acknowledged the peer-reviewed science linking neonicotinoid pesticides to colony collapse disorder and bee decline, as is the case with the European Union’s European Food Safety Authority (EFSA), where neonicotinoids are being phased out. Specifically, the new label applies to pesticide products containing the neonicotinoids imidacloprid, dinotefuran, clothianidin and thiamethoxam. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid […]

(Beyond Pesticides, August 15, 2013) Many “bee friendly” home garden plants sold at Home Depot (NYSE: HD), Lowe’s (NYSE: LOW) and other leading garden centers have been treated with pesticides shown to harm and kill bees, according to a pilot study released yesterday by   Friends of the Earth-US, Beyond Pesticides,  and others.  Supporting organizations sent a  letter  yesterday —along with petitions signed by more than 175,000 people— to Lowe’s, Home Depot, Target and other top garden retailers, asking the stores to stop selling neonicotinoids and plants treated with the pesticides. A majority of the UK’s largest garden retailers, including Homebase, B&Q and Wickes, have already stopped selling neonicotinoids. The pilot study, co-authored by the Pesticide Research Institute, found that 7 of 13 samples of garden plants purchased at top retailers in Washington DC, the San Francisco Bay Area and Minneapolis contain neurotoxic pesticides known as neonicotinoids that studies show harm or kill bees and other pollinators. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. These systemic pesticides, which  move through the plant’s vascular system and express themselves through pollen […]

(Beyond Pesticides, July 29, 2013) Researchers at the U.S. Department of Agriculture (USDA) and University of Maryland have found that low levels of pesticide exposure from crop pollination make honey bees more susceptible to the deadly gut parasite, Nosema ceranae, contributing to declines in bee populations. The study’s findings, released Wednesday July 24 in the journal PLoSONE, expand on a recent report released by the USDA that found parasites, disease, genetics, poor nutrition, and pesticide exposure as synergistic factors in the observable nationwide honey bee decline, but focused on technological stopgap measures without questioning the  sustainability of widespread systemic neonicotinoid pesticide use.  Adding urgency to USDA’s research, another study released just last Monday in the Proceedings from the National Academy of Sciences shows that pollinator losses can have a detrimental effects on plant reproduction. Pesticide Exposure and Susceptibility to Disease The newest USDA research adds to the growing body of evidence that shows pesticide exposure weakens honey bees’ immune system making them more susceptible to parasites and pathogens. Researchers took pollen samples from crops that honey bees are known to pollinate including apples, watermelons, pumpkins, cucumbers, blueberries, and cranberries to determine exposure levels and Nosema infection. In sum, researchers found […]

(Beyond Pesticides, July 17, 2013) Capitol Hill is buzzing about a new bill that aims to provide long overdue protections for America’s imperiled pollinators. Representatives John Conyers (D-MI) and Earl Blumenauer (D- OR) introduced H.R. 2692,   The Saving America’s Pollinators Act, calling for the suspension of neonicotinoids, a class of systemic pesticides that are killing bees. Tell your Representative to Save America’s Pollinators! The United States is lagging behind our European neighbors when it comes to the protection of pollinator health. Earlier this year, the EU announced a two-year suspension on these bee-killing pesticides. Now it’s time for the U.S. to act. The Save America’s Pollinators Act will suspend the use of neonicotinoid pesticides until a full review of scientific evidence and a field study demonstrates no harmful impacts to pollinators. Following the introduction of the legislation, Reps. Conyers and Blumenauer issued the following statement: Rep. John Conyers, Jr. (D-Mich): “One of every three bites of food we eat is from a crop pollinated by honey bees. These crops include apples, avocados, cranberries, cherries, broccoli, peaches, carrots, grapes, soybeans, sugar beets and onions. Unfortunately, unless swift action is taken, these crops, and numerous others, will soon disappear due to […]

(Beyond Pesticides, July 3, 2013) In light of recent action in Europe to suspend to use of certain neonicotinoid pesticides, Beyond Pesticides joined 12 other environmental and advocacy organizations in urging the Obama administration to direct the U.S. Environmental Protection Agency (EPA) to follow the European Union’s (EU) lead in recognizing that risks posed by these pesticides are unacceptably high, and suspend the use of these chemicals in the U.S. to protect pollinators and the nation’s agricultural economy. The letter urges the Obama administration to not only direct EPA to follow Europe’s lead in suspending certain neonicotinoid pesticides uses, but requests even more protective measures, including a minimum two-year suspension for all outdoor uses of neonicotinoid insecticides pending resolution of their hazards to bees and beneficial organisms. Highlighting the negative environmental and economic impacts of outdoor uses of the EPA-approved neonicotinoid insecticides: imidacloprid, clothianidin  , thiamethoxam, dinetofuran and acetamiprid, as well as a recognition that the initial risk assessments for these chemicals fail to adequately consider key risks to bee health, the letter to President Obama notes that it, “would not be responsible to continue to allow these threatening compounds to be used so broadly.” On average, U.S. beekeepers lost […]

(Beyond Pesticides, July 2, 2013) In the wake of massive bee kills, the Oregon Department of Agriculture (ODA) is placing temporary restrictions on the use of pesticides with the active ingredient dinotefuran. Dinotefuran, a neonicotinoid pesticide, was confirmed as the cause of one massive bee die-off in Wilsonville, Oregon, and suspected as the cause of another bee die off in Hillsboro, Oregon. This temporary restriction will be in place for 180 days for a limited number of dinotefuran uses. Environmental advocates have sued EPA  on neonicotinoid  pesticides, citing its regulatory process  as deficient in  protecting bees and other beneficial organisms. Just as Pollinator Week 2013 began, an estimated 50,000 bumblebees, likely representing over 300 colonies, were found dead or dying in Wilsonville. According to the Xerces Society, this was the largest known incident of bumblebee deaths ever recorded in the country. After a preliminary investigation, ODA confirmed that the massive bee die-off was caused by the use of the insecticide dinotefuran. Then, it was reported by The Oregonian that hundreds of bees were found dead after the same pesticide was used in the neighboring town of Hillsboro. Dan Hilburn, director of plant programs at the Oregon Department of Agriculture (ODA), […]
