(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

(Beyond Pesticides, November 14, 2018) Monarch butterflies are in the midst of a staggering decades-long population decline that has rapidly accelerated since 2005, research published by an international team of scientists and the University of Florida last month indicates. According to data meticulously collected by researchers, monarchs making their way to central Florida after emerging from their breeding grounds in Mexico have declined by 80% over the last decade and a half. This is roughly the same time frame at which beekeepers began to see precipitous declines in managed honey bee colonies. Researchers point to industrial development and increasing pesticide use as factors that have accelerated the decline of this iconic species. “A broad pattern is that 95 percent of corn and soybean products grown in the U.S. are Roundup Ready crops that resist glyphosate,” said study coauthor Earnest Williams, PhD, of New York’s Hamilton College in a press release. “That has a national impact. What’s really needed are patches of native vegetation and nectar sources without pesticides. It’s not just for monarchs but all pollinators.” Beginning in 1985, renowned monarch expert Lincoln Brower, PhD and his team monitored monarch populations at a pesticide-free cattle pasture south of Gainesville, FL. […]

(Beyond Pesticides, November 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee “reproducers,” namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the study’s authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, October 25, 2018) A study published last month in Scientific Reports finds that eating sunflower pollen significantly reduces protozoan infection in bumblebees. Studying ecosystem services and what she calls “floral rewards,” evolutionary ecologist Lynn Adler, Ph.D. at the University of Massachusetts Amherst says sunflowers may provide a long sought after solution for improving bees’ immune system response to both disease and parasites. The researchers studied the protozoan Crithidia bombi, a common parasitic infection of bumble bees, known to impair learning and foraging, shorten lifespan and destabilize colony hierarchies by impacting queen bee behavior. From the outset of the study, Dr. Adler says, “the more sunflowers were grown at the farm, the lower the Crithidia load for the bees at that farm.” Knowing pollinators eat pollen as a source of protein and healthy fats, Dr. Adler hypothesized that both pollen and nectar might have medicinal effects against disease and parasites. However, her experiment did not show consistent results with nectar. After bees in the lab were starved for 4-6 hours, researchers fed individual worker bees from small colonies a drop of fructose fluid containing 6,000 Crithidia cells, being the approximate concentration bees may encounter in the wild while foraging. After […]

(Beyond Pesticides, September 12, 2018) The city of Amsterdam, Netherlands is leading global bee recovery efforts by increasing its diversity of wild pollinator species, according to reporting and an analysis by NBC News. A new map published by the city identified 21 bee species not found in an earlier 1998 survey recorded by Amsterdam officials. The increase has been attributed to a range of pollinator-protective measures, including a ban on bee-toxic pesticides and the planting of native flowers, prioritized by the city government since the turn of the century. Local communities throughout the world can look to Amsterdam for policies and practices that will safeguard their own unique pollinator populations. The NBC News report notes several initiatives undertaken by the Amsterdam government. Many of these measures come out of a $38.5 million fund aimed at broadly improving environmental sustainability. “Insects are very important because they’re the start of the food chain,” said Geert Timmermans, an Amsterdam ecologist to NBC News. “When it goes well with the insects, it also goes well with the birds and mammals.” Insect and bee hotels are often installed in conjunction with the development of green roofs, which are encouraged for all new buildings. And parks […]

(Beyond Pesticides, August 29, 2018) As pesticides drain from agricultural fields, they can poison waterways and coastal areas and harm wildlife. Now, a study finds that a gene that helps terrestrial mammals break down certain toxic chemicals appears to be faulty in marine mammals — potentially leaving manatees, dolphins and other warm-blooded aquatic life more sensitive to toxic pesticides, especially organophosphates. As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that has the effect of defending humans and other land-dwelling mammals from the neurotoxic effects of certain pesticides. The gene, PON1, carries instructions for making a protein that interacts with fatty acids ingested with food. But that protein has taken on another role in recent decades: breaking down toxic chemicals found in a popular class of pesticides – organophosphates. An inspection of the genetic instructions of 53 land mammal species in the study, “Ancient convergent losses of Paraoxonase 1 yield potential risks for modern marine mammals,” found the gene intact. But in six marine mammal species, Paraoxonase 1 (PON1) was riddled with mutations that made it useless. The gene became defunct about 64 million to 21 million years ago, possibly due to dietary or behavioral changes related to […]

(Beyond Pesticides, August 27, 2018) Beyond the visual and audial charms of some bird species, insect-eating birds play a significant role in controlling pests that can ruin crops or ravage forests. A meta-study by Martin Nyffeler, Ph.D. of the University of Basel in Switzerland finds that globally, birds annually consume 400-plus million metric tons of various insects, including moths, aphids, beetles, grasshoppers, crickets, and other arthropods (invertebrate organisms with exoskeletons, paired and jointed appendages, and segmented bodies, such as insects, crustaceans, and spiders). This research reviews 103 studies that examine the volume of insects consumed by various birds in seven of the world’s major biomes. In consuming such volumes of insects that can inflict damage on crops, trees, and other plants on which organisms may feed or otherwise depend, birds provide significant services to ecosystems, to denizens of habitats, and to human food system and economic interests; they also keep local ecosystems in balance. Threats to birds — and thus, to those ecosystem services — include those from pesticide use. Of the 10,700 known bird species distributed across the planet, more than 6,000 are primarily insectivorous. The study indicates that forest-dwelling birds consume the majority of insects (approximately 300 million metric […]

(Beyond Pesticides, July 30, 2018) In place of open debate, Congressional Republicans have once again used riders in three must-pass funding and authorization bills to remove protection from endangered species. It adds up to a huge attack on an immensely popular law. From wolves and grizzly bears to monarchs and burying beetlehttps://action.beyondpesticides.org/p/dia/action4/common/public/?action_KEY=26387s, everyone is at risk. Wolves could lose protection nationwide. Toxic pesticides could be exempt from environmental review. Threatened wildlife could be forced to wait for lifesaving protection while industry gets the green light to destroy our public lands. And that’s just a glimpse of what Congress is trying to get away with. Tell your U.S. Senators to oppose these attacks on the Endangered Species Act. Avoiding direct conflict with a law supported by about 83 percent of Americans (including a large majority of conservatives), according to an Ohio State University poll, Congress has launched hundreds of backdoor attempts to gut the Endangered Species Act and sidestep the laws that protect our air, water, and public lands. If passed, they would change which species get protected, how critical habitat is chosen, and whether climate change can be considered a factor at all. The sneak attacks include: National Defense Authorization Act: […]

(Beyond Pesticides, July 12, 2018) Neonicotinoid insecticides have become notorious for their impacts to insect pollinators like bees and butterflies, but research finding the presence of these chemicals in wild turkeys is raising new concerns about the ubiquitous nature of these chemicals once released into the environment. Published in Environmental Science and Pollution Research by a team from the University of Guelph (UG), this new study highlights the broader effects of neonicotinoids on wildlife, and underlines calls to restrict the use of these products in favor of a more sustainable pest management approach. Looking at roughly 40 wild turkeys in southern Ontario, researchers found 10 that contained pesticide residue in their livers. Claire Jardine, PhD, pathobiology professor and study co-author notes that wild turkeys in agricultural regions are more likely to be contaminated. “Wild turkeys supplement their diet with seeds from farm fields,” she indicated in a press release. The agrichemical industry coats a majority of corn and soybean seeds with neonicotinoids prior to planting. Because of their systemic nature, neonicotinoids are incorporated the seedlings as they grow, with the promise by the industry that this will alleviate pest pressure. However, a significant body of research, including EPA studies, have […]

(Beyond Pesticides, July 9, 2018) The Center for Biological Diversity (CBD) is urging the U.S. Fish and Wildlife Service (FWS) to take action to protect 23 wildlife species in the Southeast that are at risk of extinction. Citing deep concerns about unprecedented assaults on the Endangered Species Act (ESA), CBD’s letter reiterates the critical need for FWS to provide timely protection to the most critically imperiled species. Urge FWS to provide Endangered Species Act protection for 23 species in the Southeast. Urge your U.S. Senators and Representative to support the ESA’s scientific review process and protect endangered and threatened species and their habitats. CBD’s letter highlights the plight of 23 freshwater animals and plants, including the southern snaketail and the sunfacing coneflower, and the failure of FWS to meet its deadlines for issuing proposals on species determined “may warrant protection.” CBD urges FWS to follow the law –to review and publish species protection proposals. A declining budget and opposition from the Trump administration are stalling these critical protections. The Trump administration has proposed slashing the budget for endangered species listings by half, from $20.5 million to $10.9, and to prioritize delisting species rather than granting protection to new ones. These budget […]

(Beyond Pesticides, July 6, 2018) Two years ago, thirteen bald eagles were found dead on a farm in Maryland. Now the investigation has revealed that these birds died after ingesting the highly toxic pesticide, carbofuran. Carbofuran, whose use has been phased out in the U.S., is so toxic to birds that one granule is all it takes to kill. Irresponsible and illegal use of pesticides is still responsible for primary and secondary poisonings of wildlife, as is the case of these bald eagles. According to the necropsy results by U.S. Fish and Wildlife Service (FWS), which analyzed six of the thirteen eagle carcasses, five of the carcasses were found to have undigested raccoon remains in their systems. Carbofuran was detected in the stomach and/or crop contents of all birds, as well as on the partial remains and fur of a raccoon that was found nearby. The granular form of carbofuran has been blamed for the deaths of more than a million birds in the U.S. who mistook the granules for seed. The granules were finally banned in the early 1990s, while the liquid formulation was banned on food crops in 2009, although the painfully slow process of cancellation by the U.S. […]

(Beyond Pesticides, June 21, 2018) In a letter sent by the Center for Biological Diversity (CBD), the U.S. Fish and Wildlife Service (FWS) is being urged to complete status reviews and listing proposals for 23 wildlife species in the Southeast that are at risk of extinction. Citing deep concerns about unprecedented assaults on the Endangered Species Act (ESA), the letter reiterates the critical need for FWS to provide timely protection to the most critically imperiled species. Highlighting the plight of 23 freshwater animals and plants, like the southern snaketail and the sunfacing coneflower, and the consideration by the Trump Administration to withdraw ESA findings for dozens of species, CBD submitted the letter, dated June 8, 2018, urging FWS to follow the law, and review and publish species protection proposals. CBD initiated a review of 61 species for which the group had already filed a petition seeking ESA protections. This came after the Trump administration’s unprecedented move to reverse an Obama-era decision to review the status of the species because available information indicates they may warrant listing. CBD first petitioned FWS for their protection in 2010. Hundreds of other highly imperiled species are similarly awaiting decisions, but, according to CBD, a […]

(Beyond Pesticides, May 30, 2018) Six environmental groups have sued the Trump Administration for reversing a long standing interpretation of the Migratory Bird Treat Act (MBTA) that provides migratory bird protections from incidental killing or “taking” caused by industrial activities. The lawsuit, National Audubon Society v. Department of the Interior, was filed May 24, 2018 in the Southern District of New York, challenging as “unlawful and arbitrary and capricious the December 22, 2017 Solicitor’s Memorandum M-37050, which was issued by the office of the Solicitor of the Department of the Interior (“DOI”) and reverses Defendants DOI’s and the U.S. Fish and Wildlife Service’s (“FWS” or “Service”) longstanding interpretation and implementation of the Migratory Bird Treaty Act of 1918.” The Act’s prohibition on the killing or “taking” of migratory birds has long been understood to extend to incidental take from industrial activities — meaning unintentional but predictable and avoidable killing. Last year, the Trump Administration issued a Memorandum gutting federal protections for migratory birds under the Migratory Bird Treaty Act (MBTA). The plaintiffs, including American Bird Conservancy, Center for Biological Diversity, Defenders of Wildlife, National Audubon Society, National Wildlife Federation, and the Natural Resources Defense Council, are seeking to protect waterfowl, […]

(Beyond Pesticides, May 29, 2018) The Farm Bill is beginning to move in the U.S. Senate Committee on Agriculture, Nutrition, and Forestry, and your voice is critically needed to help stop provisions that are harmful to health and the environment. Tell your U.S. Senators and Representative that they should vote against the Farm Bill unless harmful provisions to health and the environment are removed. In addition to sending this urgent action on the Farm Bill, consider reaching out to your U.S. Senators and Representative when they return to your state for the Memorial Day holiday. If you’re part of a group, ask for a meeting. If you see them at an event or in town, let them know how important it is to keep the dangerous provisions listed below out of the Farm Bill. The Farm Bill in the U.S. House of Representatives, H.R. 2, reported favorably out of the House Agriculture Committee, is stalled, after being defeated on the floor over unrelated immigration legislation. The House bill is a direct attack on organic standard setting, the authority of local governments to restrict toxic pesticides, and the protection of farmworkers, endangered species, and the environment. Without public outcry, it is likely […]

(Beyond Pesticides, May 15, 2018) According to a new report from the Center for Biological Diversity (CBD), hundreds of thousands of pounds of pesticides are sprayed on lands that are designated as refuges for wildlife and protected under U.S. law. Approximately 490,000 pounds of pesticides have been sprayed on crops grown in national wildlife refuges in 2016 alone. Pesticide use in these sensitive areas poses risks to pollinators, aquatic organisms, migratory birds, and other wildlife on refuges that were created to protect them. The report, No Refuge, released last week, analyzes pesticide use on national wildlife refuges using records obtained through a Freedom of Information Act request. The report finds that in 2016 more than 270,000 acres of refuge lands were sprayed with pesticides for agricultural purposes. Five national wildlife refuge systems are identified as most reliant on pesticides for agriculture: Klamath Basin National Wildlife Refuge Complex in California and Oregon, with 236,966 pounds of pesticides; Central Arkansas Refuges Complex in Arkansas, with 48,725 pounds of pesticides; West Tennessee Refuge Complex in Tennessee, with 22,044 pounds of pesticides; Tennessee National Wildlife Refuge Complex in Tennessee, with 16,615 pounds of pesticides; and, Chesapeake Marshlands National Wildlife Refuge Complex on the Eastern Shore of Maryland and Virginia, with […]

(Beyond Pesticides, January 17, 2018) The organophosphate insecticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). The insecticide cholorpyrifos, whose ban was rescinded by the Trump Administration last year, despite overwhelming evidence of neurological and brain damage to children, is once again being shown to be too toxic for continued use. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that it “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects to species and their designated habitats. These include “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g. fish, mammals, invertebrates); specific chemical characteristics of each pesticide (e.g. degradation rates, bioaccumulation rates, sorption affinities, etc.); expected environmental concentrations calculated for generic aquatic habitats; authorized pesticide product labels; maps showing the spatial overlap of listed species’ habitats with pesticide use areas; […]

(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, November 20, 2017) The pesticide industry is drafting legislation that threatens to remove provisions of the Endangered Species Act that protect species from pesticides. Tell your Congressional delegation to oppose all efforts to reduce endangered species protections from pesticides. The Endangered Species Act (ESA) is one of America’s most effective and important environmental laws. It represents a commitment to protect and restore those species most at risk of extinction. Recent polling shows 84 percent of Americans support the Endangered Species Act, and 87 percent agree that it is a successful safety net for protecting wildlife, plants, insects, and fish from extinction. Although many species –including the bald eagle, Florida manatee, and California condor— have been protected and brought back from the brink of extinction under the ESA, an estimated 500 species have disappeared in the past 200 years. An important provision of the ESA is the requirement that each federal agency that proposes to authorize, fund, or carry out an action that may affect a listed species or its critical habitat must consult with the U.S. Fish and Wildlife Service and National Marine Fisheries Service. In the case of pesticides, EPA is required to perform such a consultation if […]

(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, 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, August 23, 2017) The Center for Food Safety (CFS) filed a federal lawsuit to stop the U.S. Army Corps of Engineers from moving forward with an expansion of industrial shellfish aquaculture on the Washington state coast without any water quality or marine life protections from pesticide use and habitat loss. This is just the latest in efforts to protect sensitive coastal areas in Washington from shellfish farming that is contributing to increased pesticide use and environmental degradation. The lawsuit, filed in the U.S. District Court for the Western District of Washington earlier this month, challenges the U.S. Army Corps of Engineers (Corps) issuance of a nationwide permit (NWP 48), which, according to the suit, “greenlights a massive expansion of shellfish aquaculture with entirely inadequate protections.” The Corps has a duty to protect public water from adverse impacts, but potential environmental impacts have not properly assessed or considered, the suit claims, in violation of the Corps’ environmental protection mission. The lawsuit argues that the Corps, when it approved the Washington state permit, violated numerous environmental laws, including the Clean Water Act, National Environmental Policy Act, and Administrative Procedure Act. According to CFS, the permit issued will allow shellfish aquaculture acreage […]

(Beyond Pesticides, July 17, 2017) Last week, Center for Food Safety (CFS) filed a legal petition demanding major updates and improvements to the U.S. Environmental Protection Agency’s current review of pesticides. The petition specifically seeks to compel EPA to require that pesticide companies provide safety data on all ingredients of a pesticide products, or formulations, both active and inert. The agency generally only requires data on a pesticide product’s active ingredient, despite evidence of potential hazards associated with synergism between ingredients, including inert (undisclosed) ingredients, and other pesticides applied in combination. According to Amy van Saun, attorney with CFS, “EPA’s job is to ensure pesticides are safe for children, families, and the environment, but numerous pesticides have other ingredients or combined effects that are causing significant risks and harm. EPA’s outdated and insufficient safety assessment endangers the public welfare and must be brought into the 21st century.” The CFS petition requests the following actions from EPA: Revise pesticide registration regulations to take into account all pesticide ingredients (active, inert and adjuvant) and their effects on the environment. Revise pesticide registration regulations to require whole pesticide formulation and tank mixture testing to take into account synergistic effects. Revise pesticide registration regulations to require inert […]
