(Beyond Pesticides, January 4, 2018) Last month, the U.S. Environmental Protection Agency (EPA) released the preliminary ecological (non-pollinator) assessments for the neonicotinoids (neonics); clothianidin, thiamethoxam, dinotefuran, and the terrestrial ecological assessment for imidacloprid, finding that these pesticides pose both acute and chronic risks to aquatic life and birds. Treated seeds are identified as posing the highest dietary risks to birds, confirming previous research that neonics are highly hazardous not only to bees, but to birds, aquatic life, and other non-target organisms. Released December 15, 2017, EPA opened the public comment period for these assessments until February 20, 2018. Along with the risks identified in the assessments, the agency is specially requesting feedback on the benefits of continued use of the neonics in cotton and citrus crops identified in last year’s pollinator assessments as posing risks to honey bees. EPA states, “We believe early input from the public will be helpful in developing possible mitigation options that may be needed to address risks to bees.” This despite evidence of long-term systemic exposures to non-target organisms that support a phase-out of these pesticides. EPA believes that neonicotinoids are crucial for the management of Asian citrus psyllid, an invasive pest that causes citrus greening, […]

(Beyond Pesticides, December 14, 2017) Tests of waterways in the United Kingdom (UK) reveal rivers contaminated with neonicotinoids, the class of chemicals highly toxic to bees and aquatic invertebrates. And now, although neonicotinoids were banned from use on certain crops in the European Union (EU) in 2013, an EU vote to extend the ban has been delayed. The test results raise concerns over neonicotinoids’ impacts on waterways, especially to fish and birds. Under a new EU mandate -Water Framework Directive â€Watch List’ initiative – the UK was required to monitor for all five commonly used neonicotinoids: imidacloprid, clothianidin, thiamethoxam, acetamiprid and thiacloprid. Twenty-three sites were sampled in 2016, 16 in England, four in Scotland, three in Wales and three in Northern Ireland. This is the first systematic testing of neonicotinoids in rivers in Britain. According to the results, half the rivers tested in England had either chronic or acute levels of contamination. Of the 23 rivers tested across Britain, all but six contain neonicotinoids. Eight rivers in England exceed recommended chronic pollution limits, and two are acutely polluted. Neonicotinoids are not only highly toxic to bees but also highly toxic to aquatic insects, which are a vital food source to […]

(Beyond Pesticides, December 11, 2017) Tell the Natural Resources Conservation Service (NRCS) to substantially increase the amount of funding spent on the conservation of monarch butterflies and the restoration of their habitat, and to ensure that restored habitat is not poisoned with hazardous pesticides. Although the agency has taken some steps to protect monarchs –including the implementation of the Monarch Butterfly Habitat Development Project and support for the Monarch Butterfly Conservation Fund— last year’s NRCS expenditure of $4 million was insufficient to prevent the monarchs’ decline, and could not even begin stemming the loss of milkweed habitat. Restoring the monarch butterfly and its habitat will require a substantial contribution from the agricultural sector and strong leadership from the NRCS. Agricultural lands encompass 77% of all prospective monarch habitat, and thus are indispensable to reaching these goals. Monarch populations have fallen more than 80 percent over the last 20 years, and it is estimated that there is a 60 percent chance the multigenerational migration of these butterflies would completely collapse in the next 20 years. Milkweed, the only forage for monarch caterpillars, has decreased by 21 percent, especially in the Midwest, where agricultural fields and pesticide use have expanded. Scientists estimate […]

(Beyond Pesticides, December 6, 2017) Last week over 100 conservation and environmental groups urged the federal government to increase funding to protect and conserve monarch butterflies. These iconic butterflies, native to North America, have seen drastic declines in their populations. Surveys report over 80 percent reductions in populations over the last 20 years. Pesticide use, habitat loss, and climate change have all been identified as stressors to these butterflies. The groups, led by the Center for Biological Diversity, Defenders of Wildlife, and the Humane Society, sent a letter to the U.S. Department of Agriculture (USDA) to do more to help the imperiled butterfly. The letter requests the agency increase the allotment of conservation funds from $4 million- spent last year- to $100 million. The increase in funds is needed for efforts to increase milkweed habitat. In contrast, the government spent over $500 million on sage grouse initiatives to prevent that animal’s listing under the Endangered Species Act (ESA), even though the Trump Administration is seeking to overturn these initiatives. Currently, the agency has taken some steps to protect monarchs. These include the implementation of the Monarch Butterfly Habitat Development Project and support of the Monarch Butterfly Conservation Fund. But, according […]

(Beyond Pesticides, December 5, 2017) Fungicides are likely playing an important role in the decline of North American bumblebee populations, according to new research published by a team at Cornell University. While overwhelming data continue to indicate that insecticides, particularly the neonicotinoid class of chemicals, are the leading factor in overall pollinator declines, Cornell scientists discovered that fungicides, in particular the chemical chlorothalonil, are likely compounding risk and toxicity for U.S. bumblebee species. As new studies continue to expand the chemical culprits in pollinator declines, calls for a wholesale change in agricultural practices toward more sustainable organic production are reinforced. Cornell researchers began their investigation by focusing on what land use factors had the most impact on eight bumblebee species, many of which have been declining in the U.S. Bumblebee species were sampled at nearly 300 sites in 40 states during the summer months, and at each of the sampling sites, landscape variables were characterized and quantified for land use (urban v rural), habitat (high vs low latitude), and pesticide (insecticide, fungicide, herbicide) usage. The strongest indicator of declining range within the selected bumblebee species was found to be overall fungicide use, with those in the northern U.S. undergoing the […]

(Beyond Pesticides, December 1, 2017) Ichneumonid wasps (family Ichneumonidae), are a widely distributed parasitoid wasp family within the order Hymenoptera. The name “ichneumonid” comes from Greek words meaning “tracker” and “footprint.” And females do indeed hunt for suitable “hosts” by first identifying the organism’s food source. Once a suitable host is found, females deposit eggs onto the unsuspecting insect larvae where, within ten days to several weeks, the Ichneumonid larva kills the host by feeding on its body fluids before it emerges. They are also known as “scorpion wasps” for the extreme length and curving motion of their segmented abdomens. Note: both adult males and females are stingless, and feed on nectar. The discovery of Ichneumonidae was so troubling to many that, in 1860, Charles Darwin wrote a letter to the American naturalist Asa Gray, saying: “I own that I [should wish to] see as plainly as others do…evidence of design and beneficence on all sides of us…I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice.” The parasitic behavior of Ichneumon wasps was […]

(Beyond Pesticides, November 30, 2017) A French court suspended the license of two pesticide products citing their toxicity to bees. The products, Closer and Transform, both contain the active ingredient, sulfoxaflor, which is highly toxic to bees. The ruling overturned the decision by France’s health and environment agency, ANSES, to allow the use of the sulfoxaflor products. Sulfoxaflor use was also challenged in the U.S. by beekeepers concerned about its impact on already declining bee populations. Sulfoxaflor is a relatively new active ingredient whose mode of action is similar to that of neonicotinoid pesticides. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is a new generation of neonicotinoid. Its initial 2013  U.S. registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and the U.S. Environmental Protection Agency’s (EPA) inadequate review of the data. The court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may have on honey bee colonies. By vacating EPA’s unconditional registration of the chemical, sulfoxaflor could not be used […]

(Beyond Pesticides, November 28, 2017) Bumblebees exposed to field-realistic levels of neonicotinoid insecticides have problems with “buzz pollination” that results in reduced pollen collection, according to new research published in Scientific Reports. This is the latest science to tease out the complex ways in which neonicotinoids interfere with these important pollinators, providing yet another reason to eliminate these highly toxic, systemic insecticides from the environment. Flowers that bumblebees pollinate require the insects to emit soundwaves, or â€sonicate’ to release their pollen, and bumblebees must perfect their techniques over time in order to maximize the pollen they are able to collect. Researchers tested the effect of neonicotinoids on bumblebees’ sonication abilities by exposing them to field realistic doses of the insecticide thiamethoxam at rates of 2 parts per billion (ppb) and 10 ppb, and observing their ability to successfully collect pollen. A control group that never came in contact with thiamethoxam was also used to compare the progress of the exposed group. Lead author of the study, Penelope Whitehorn, PhD, indicated, “We found that control bees, who were not exposed to the pesticide, improved their pollen collection as they gained experience, which we interpreted as an ability to learn to buzz […]

(Beyond Pesticides, November 22-23, 2017) As we sit with friends and family this Thanksgiving, let us appreciate how our delicious meal got to your table. The turkey, potatoes, stuffing, and cider all originated in fields far from our homes, and those working in those fields deserve our thanks. They deserve our thanks because many of these workers work long hours, under deplorable conditions, and are exposed to pesticides that put their health and that of their families at risk. So, as we enjoy our pumpkin pie, cranberry sauce, and apple crumble, remember all the hardworking farmworkers who have helped to bring our meal to the Thanksgiving table. At the same time, we give thanks for the environment that is so plentiful and nurturing of life, and remember the importance of pollinators and biodiversity in sustaining life. Celebrating Thanksgiving and looking toward another year coming to an end, provides an opportunity for us to remember to remain vigilant, and raise our voices against efforts to erode our environmental protections that safeguard human health and preserve biodiverse ecosystems. Thanking Farmworkers Farm work is hard and dangerous work. Each year millions of farmworkers, including seasonal and migrant workers, toil in fields across the […]

(Beyond Pesticides, November 15, 2017) Songbirds exposed to widely used insecticides fail to properly orient themselves for migration, according to a study published by Canadian scientists in Scientific Reports. With the organophosphate chlorpyrifos and the neonicotinoid imidacloprid applied to millions of acres of farmland throughout North America, this new research adds weight to arguments that pesticides are a likely cause in the decline of migratory bird populations. “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides,” said Christy Morrissey, PhD, biology professor at the University of Saskatchewan. Researchers captured 57 white crowned sparrows in northern Canada, and held them in an outdoor pen for roughly two weeks, during which time all the birds either gained or maintained their weight. The songbirds were then split into three groups, one exposed to imidacloprid, another to chlorpyrifos, and the last untreated and acting as a control. The imidacloprid and chlorpyrifos exposed groups were each further separated by exposing a portion to the insecticide at 10% of the lethal dose that would kill 50% of a given population (LD50), and another to 25% […]

(Beyond Pesticides, November, 8, 2017) Farmers who purchased and handled Monsanto’s new treated seed product, NemaStrike, for nematode or roundworm control (nematicide) have been reporting skin irritation, including rashes that occurred after use. Now the seed giant is pausing a full rollout of the product, while blaming farmers for not using gloves and other protective equipment to handle the treated seeds. This is another blunder from Monsanto and the latest incident highlighting the deficiencies in the U.S. Environmental Protection Agency’s (EPA) pesticide registration process in light of the millions of acres of crop damage from Monsanto products green-lighted by EPA. While touting that NemaStrike went through three years of extensive field trials and “extensive evaluations” by EPA, Monsanto stated in a bulletin to its customers on its website that it will pause commercialization of the product in light of reports of skin irritation from users. These adverse reactions to the product are being blamed on the failure of users to wear gloves and other protective equipment when handling the treated seeds. This is not the first time that Monsanto has tried to shift responsibility for the toxic effect of its products to users. Last year, Monsanto blamed farmers for drift […]

(Beyond Pesticides, November 2, 2017) The Baltimore oriole (Icterus galbula) is Maryland’s state bird and the namesake of its professional baseball team. The Baltimore oriole (and all American orioles) are actually members of the blackbird family, and are related to the tricolored blackbird. For a time, the Baltimore oriole was “lumped” together with the Bullock’s oriole to the west under the name “northern oriole.” The “splitters” have won out again, and the two are recognized as separate species, except in the Western prairies, where they hybridize. In fact, the Baltimore oriole shows more genetic similarities to the Altamira oriole (which lives in Mexico, northern Central America, and a tiny part of Texas), and especially to the black-backed oriole (from Mexico). Fun fact: The Baltimore orioles’ slender beaks allow them to feed in an unusual way. By first piercing soft fruits with their closed bills, the birds open their mouths to cut a strip through the juicy fruit, allowing them to drink the gushing liquid with their brushy-tipped tongues, in a process called “gaping.” Range Baltimore orioles are commonly found during spring and summer months in the eastern and central U.S., and in southern Canada. They will migrate in July to […]

(Beyond Pesticides, October 30, 2017) Tell the Arkansas State Plant Board to stand up to Monsanto, and protect farmers by banning dicamba’s use in Arkansas agriculture. Comment period closes today, Monday, October 30, 2017, at 4:30pm (Eastern Time). Your comments are needed to stop the disaster in Arkansas being created by Monsanto’s new genetically engineered (GE) cropping system, which relies on the toxic pesticide dicamba. If Arkansas bans dicamba, other states should and will follow —given the chemical industry’s takeover of the U.S. Environmental Protection Agency (EPA), which is allowing this extremely hazardous pesticide use. This is a problem that has regional and national implications, given the breakdown of the EPA and its pesticide program. We cannot let this failure of protection stand in Arkansas or anywhere in the country. Promoted by Monsanto as a way to address rampant Roundup (glyphosate) resistance, Monsanto’s new GE soybeans are now able to withstand both glyphosate and dicamba, an older herbicide with a range of documented health effects —from neurotoxicity to reproductive problems. Dicamba is also highly volatile and, as a result, has drifted across crop fields throughout the region, damaging high value fruit tree and organic operations. The Arkansas State Plant Board is […]

(Beyond Pesticides, October 25, 2017) Oregon is the most recent site of an effort by a locality to establish more-protective pesticide regulations than are provided by the state. Voters in Lincoln County, on the north-central Oregon Coast, approved a ballot measure earlier this year that established a ban on aerial spraying of pesticides in the county. Immediately, county landowners Rex Capri and Wakefield Farms, LLC, both of whom use aerial spraying on their properties, filed a legal challenge to the ordinance created through that vote. The issue is whether the state of Oregon has the legal authority to stop its local political subdivisions from adopting more rigorous than those enacted by the state. When the state of Maine considered legislation to preempt its local jurisdictions (take away their authority to act) this summer, Beyond Pesticides wrote, “The democratic process is foundational to the culture of Maine and the country. LD 1505 betrays the democratic process. Maine communities want to be able to adopt standards that exceed or are more stringent than state standards as a matter of public health and environmental protection, or quality of life. Why would a town or city want to do use its local authority to adopt […]

(Beyond Pesticides, October 24, 2017) Over 75% of insect abundance has declined over the last 27 years, according to new research published by European scientists in PLOS One. The dramatic drop in insect biomass has led to equally dramatic pronunciations from highly respected scientists and entomologists. “We appear to be making vast tracts of land inhospitable to most forms of life, and are currently on course for ecological Armageddon,” study coauthor David Goulson, Ph.D. of Sussex University, UK, told The Guardian. “If we lose the insects then everything is going to collapse.” Looking at the range of mechanisms that could be driving this slow moving catastrophe, researchers could suss out only one plausible large-scale factor: agricultural intensification. The current study, which looked at 63 nature preserves located in Germany, follows a similar study released in 2013 that was conducted in a singular German nature preserve. That study, originally published only in German, but available translated by Boulder County Beekeepers, found that 75% of insect biomass declined in the Orbroich Bruch Nature Reserve in Krefeld, Germany from 1989 to 2013. That study was limited to a singular nature preserve, and while scientists who worked on the study described their results as […]

(Beyond Pesticides, October 20, 2017) Last week, the U.S. Environmental Protection Agency (EPA) announced that label changes to the herbicide dicamba would be made to try to minimize drift that has left thousands of acres of crops already damaged this season. The label changes include making dicamba “restricted use,” which allows only certified applicators to apply the chemical. Dicamba drift has been damaging farmers’ crops for at least two years due to the approval of new dicamba-tolerant genetically engineered (GE) crops. Advocates says that the new changes do not ensure that drift will be eliminated. According to EPA, the agency reached an agreement with the makers of dicamba, (Monsanto, BASF and DuPont) to restrict its application. This comes after hundreds of official complaints of crop damage related to dicamba across 17 states this year alone, leading to questions about the new formulation of the chemical used in genetically engineered (GE) crop productioon. New GE crops developed by Monsanto must be paired with specific formulations of dicamba, and thus led to a vast increase in dicamba use over the past couple growing seasons. Dicamba-based herbicide use has climbed dramatically as farmers have adopted, especially, Monsanto’s GE soybean seeds; in the 2017 season, 20 […]

(Beyond Pesticides, October 12, 2017) Honey throughout the world is contaminated with neonicotinoid insecticides, chemicals implicated in global decline of pollinator populations. The extent of contamination recorded in the new Science study —with the chemicals detected on every continent except Antarctica, even in honey produced in small isolated islands— is symptomatic of a world awash in toxic pesticides. The results call into question globalized mores that have permitted chemical insecticides to pervade the environment, and signal the need to transform pest management to integrated organic systems that respect nature. Neonicotinoids are systemic pesticides that are taken up by a plant’s vascular system and transported into the pollen, nectar, and guttation (drops of xylem sap) drops the plant produces. They are mobile in soil, so quantities of the chemical that are not taken up by plants after an application leach through the soil column into local waterways. Pollinators come into contact with these insecticides through their normal course of foraging and pollination. Out of 198 honey samples collected as part of a global citizen science project and subsequently tested by Swiss scientists, 75% of samples contained a measurable level of neonicotinoids. Broken down by region, North America represented the highest frequency […]

(Beyond Pesticides, October 11, 2017) Last week, the Natural Resources Defense Council (NRDC) filed a lawsuit challenging the U.S. Environmental Protection Agency’s (EPA) registration of neonicotinoid pesticides – acetamiprid, dinotefuran, and imidacloprid, and the agency’s failure to first consult with the U.S. Fish and Wildlife Service on the pesticides’ impact on threatened or endangered species. The lawsuit, filed in the U.S. District Court for the District of Columbia, challenges the failure of the federal government to evaluate the impacts of neonicotinoid pesticides (“neonics”) on threatened and endangered species, like the rusty patched bumble bee, the black-capped vireo, and the San Bruno elfin butterfly. The suit cites widespread presence of neonics in the environment which presents serious risks to wildlife across large portions of the country. It contends that they pose significant adverse consequences to threatened and endangered species. According to the lawsuit, because of toxicity and pervasive environmental contamination, NRDC is now challenging EPA’s registrations of pesticide products containing one of three main neonic active ingredients—acetamiprid, dinotefuran, and imidacloprid—and seeks vacatur of those registrations until EPA complies with the law. “The EPA ignored endangered bees, butterflies, and birds when it approved the widespread use of neonics,” said Rebecca Riley, a senior […]

(Beyond Pesticides, October 4, 2017) Beetles in the family Cantharidae are known as soldier beetles, a name that is based on the resemblance of the elyra (wing cover) to certain military uniforms. They superficially resemble fireflies (family Lampyridae), but lack light-emitting organs and the covering obscuring the head of fireflies. Like fireflies, soldier beetles are distasteful to most predators. Range There are 16 genera containing 455 species of soldier beetles native to North America, including Chauliognathus marginatus, which is commonly seen on goldenrod in late summer and early fall. Worldwide, there are about 5,100 species in 160 genera, widely distributed in all but polar regions. Most frequently active in summer and early fall, adults can be found on various flowers including sunflowers, tansy, zinnia, marigold, goldenrod, and coneflower. Females lay eggs in clusters in the soil. Larvae are mostly carnivorous, feeding on soil insects. They live through the winter under loose soil, and become active during spring. Larvae normally pupate in early summer and adults first emerge in mid-summer. Physiology The soldier beetle’s body is around ½ to Âľ inch long. Adults are black or brown, usually with red to yellow markings, an “aposematic” signal to predators, warning of an […]

(Beyond Pesticides, September 21, 2017) The First District California Court of Appeal issued an opinion Tuesday in a lawsuit challenging a California Department of Pesticide Regulation (DPR) decision to approve additional uses for two bee-killing pesticides without disclosing the impact on honeybees. Pesticide Action Network, Center for Food Safety, and Beyond Pesticides, represented by Earthjustice, filed the underlying lawsuit in 2014, seeking to halt DPR’s practice of approving ever more uses for neonicotinoid pesticides pending completion of the agency’s languishing scientific review of the evidence linking agricultural use of neonicotinoids to a global honeybee die-off. DPR began its scientific review in early 2009 after it received evidence that neonicotinoids are killing bees, but DPR has yet to complete its review or take meaningful action to protect bees. Instead, DPR has continued to allow increased use of neonicotinoids in California. “DPR acknowledged almost 10 years ago that neonicotinoids are killing bees, yet the agency has approved more and more uses for these toxic pesticides every year since,” said Earthjustice attorney Greg Loarie, who represented the groups. “It’s time for DPR to do its job and protect honeybees and the multi-billion dollar agricultural economy that bees make possible in this State.” At issue […]

(Beyond Pesticides, September 13, 2017) According to a study published in the journal Biological Conservation, Monarch butterfly populations from western North America have declined far more dramatically than was previously known and face a greater risk of extinction – 86 percent in the next 50 years. The researchers do not know the exact cause but identify habitat loss and widespread pesticide use as likely culprits. Migratory monarchs in the west could disappear in the next few decades if steps are not taken to recover the population, the study’s lead author, Cheryl Schultz, PhD, an associate professor at Washington State University Vancouver states. “Western monarchs are faring worse than their eastern counterparts. In the 1980s, 10 million monarchs spent the winter in coastal California. Today there are barely 300,000,” she said. Western monarchs (Danaus plexippus) have a spectacular migration. They overwinter in forested groves along coastal California, then lay their eggs on milkweed and drink nectar from flowers in the spring in Arizona, California, Nevada, Oregon, Washington, Idaho and Utah. They then return to their coastal overwintering sites in the fall. Eastern monarch, whose numbers are also in decline, travel instead across the border into Mexico to wait out the winter. The researchers from […]

(Beyond Pesticides, September 5, 2017) The bog copper butterfly (Lycaena epixante) is a member of the second largest family of butterflies, Lycaenidae, which includes over 4,700 species worldwide. Also known as the cranberry-bog copper butterfly, the species has strong biological ties to cranberry plants and its associated habitat. Range Bog coppers are unevenly distributed throughout Northeast United States and into Canada, with some ranging as far west as Minnesota. Populations are generally concentrated in acid bog environments containing wild cranberry, but have also been sighted in other damp acidic habitats, such as wet meadows. The butterfly requires an environment that is wet year-round, with ample sunlight. Bog coppers are highly adapted to this environment and do not migrate. Diet and Pollination The life cycle of the bog copper strongly depends on cranberry plants. Female butterflies lay single eggs leaves in late summer or early fall on the leaves of cranberry plants, usually near the edge of the bog, covered with sedges. Each female may lay 20-40 eggs. After developing into a first stage larva within the egg, the larva is protected from ice and freezing temperature during the winter by entering state of diapause, or dormancy. The egg is protected […]
