Despite Nearly 1,700 Pet Deaths from Seresto Pet Collars, Pesticide Product Remains on Market - Beyond Pesticides Daily News Blog (Beyond Pesticides, July 20, 2023) Despite evidence of toxicity to pets from Seresto pet collars (manufactured with the neurotoxic insecticide flumethrin, as well as the notorious neonicotinoid imidacloprid), the U.S. Environmental Protection Agency’s (EPA) has announced that the popular flea and tick collars will remain on the market, but with new mitigation measures. However, advocates say that these measures will do little to protect people and pets from chemical exposure using these collars. The agency will require Elanco — the manufacturer of Seresto — to conduct enhanced reporting for various factors, including adverse symptoms, veterinary community outreach, and warnings on the product’s label. Seresto, developed by Bayer and sold by Elanco, has been linked to nearly 1,700 pet deaths, injuries to tens of thousands of animals, and harm to hundreds of people. There are nontoxic ways to protect pets from fleas and other pests while protecting human family members. Children Ignored by the Agency EPA has a history of ignoring the exposure patterns to children who come into close contact with pets and their flea collars and the potential adverse health threats, opting for warnings instead of regulatory action. In 2017, EPA issued a warning for tetrachlorvinphos (TCVP) flea collars that advised: “not […]

Neonicotinoid Insecticides Keep Poisoning California Waterways, Threatening Aquatic Ecosystems - Beyond Pesticides Daily News Blog (Beyond Pesticides, September 23, 2022) According to a September 15 Environment California press release, California Department of Pesticide Regulation (CDPR) data confirm more bad news on neonicotinoid (neonic) contamination: nearly all urban waterways in three counties show the presence of the neonic imidacloprid at levels above the U.S. Environmental Protection Agency’s (EPA’s) chronic benchmark for harm to aquatic ecosystems; in five other counties, well over half showed its presence at similar levels. Neonic use is strongly correlated with die-offs and other harms to a variety of bees and pollinators, and to other beneficial organisms. These startling metrics will make the state’s efforts to protect such organisms even more challenging, according to Environment California (EC). See Beyond Pesticides’ Poisoned Waterways report for a deep dive on neonics and their impacts in U.S. rivers, lakes, and streams. The data represent 405 surface water samples taken between 2000 and 2020; those from urban waterways in Los Angeles, Orange, and San Diego counties showed that nearly 92% are contaminated at EPA benchmark violative levels; in Alameda, Contra Costa, Placer, Sacramento, and Santa Clara counties, 58% of waterways showed such levels. Many of the counties with significant contamination are in the central coast and southern regions of […]

Presence of Neonic Insecticides in Wild Turkeys Highlights Widespread Contamination of the Environment - Beyond Pesticides Daily News Blog (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 […]

Studies Add to Mounting Evidence of Neonic Dangers - Beyond Pesticides Daily News Blog (Beyond Pesticides, November 30, 2015) Last week, two studies were published that link neonicotinoid (neonic) insecticide exposure to detrimental effects in bees and butterflies. The first study, published in the international scientific journal Nature, found that bumblebees exposed to neonics suffered pollination services impairment that reduces their delivery to apple crops. The second study, published in the United Kingdom journal Peer J, used over 1,000 sites cataloged from 1984 to 2012 in the UK Butterfly Monitoring Scheme (UKBMS) database to point to the strong association between neonic use and butterfly population decline. These studies contribute to the mounting evidence that neonic insecticides are linked to pollinator decline. Neonics have increasingly been the subject of recent studies that highlight a causal relationship between neonic exposure  and harmful effects to pollinators, like foraging and reproductive complications. These effects are being identified by scientists all over the world, gradually negating industry criticism of study design. Andre Gilburn, PhD, and ecologist at the University of Stirling, led the butterfly study. He said, “Our study not only identifies a worrying link between the use of neonicotinoids and declines in butterflies, but also suggests that the strength of their impact on many species could be huge.” […]

French Researchers Solve Discrepancy in Bee-Killing Neonic Studies - Beyond Pesticides Daily News Blog (Beyond Pesticides, November 19, 2015) French scientists say that they have found the “missing link” between laboratory studies and field studies that assess the adverse effects of neonicotinoid (neonic) insecticides on bees. The study, published in Royal Society Journal Proceedings B, evaluates the effects of neonics on honey bees in field trials. After 15 years of research into the effects of neonicotinoids on bees, researchers had identified a gap between the results of toxicity assessments on individual bees in the laboratory and  impacts seen at the colony level in the field. The new two-year study made two discoveries: First, they found that field exposure to thiamethoxam combined with imidacloprid contamination is associated with a significant excess mortality in individual free-ranging bees.  Second, while colonies appeared to be able to compensate for the excess mortality and preserve population size and honey production, this was done at the expense of a change in brood laying patterns. Thus, this study provides an explanation for the “missing link” in the discrepancies between labs studies and field studies, where the former establishes harmful and fatal effects that had yet to be replicated in real-life conditions. Because the bees responded to the increased mortality with selective […]

Study Finds No Benefit to Bee-Toxic Neonic Use - Beyond Pesticides Daily News Blog (Beyond Pesticides, September 25, 2015) Neonicotinoid-treated seeds do not reduce crop damage from pests, adding to a growing body of evidence questioning the benefits of using these bee-toxic insecticides, according to a study  published in the journal BioOne. Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies and by beekeepers  as the major contributing factor in bee decline. The study,  titled Impact of Western Bean Cutworm (Lepidoptera: Noctuidae) Infestation and Insecticide Treatments on Damage and Marketable Yield of Michigan Dry Beans, examines the relationship between western bean cutworm infestation and damage in dry beans, and the use of seeds treated with the neonicotinoid thiamethoxam, as well as soil treated with aldicarb, another systemic insecticide. Researchers have concluded that neither thiamethoxam nor aldicarb reduced cutworm damage. In fact, plots treated with these insecticides had a higher percentage of defects due to feeding by pests when compared to untreated plots, which researchers believed is  attributable to factors such as fewer natural enemies. There have been additional reports and studies published over the past few years questioning the benefits of neonic use. In […]

Meeting Records Expose Industry's Influence in UK's Neonic Emergency Use Decision - Beyond Pesticides Daily News Blog (Beyond Pesticides, July 31, 2015) New information has surfaced regarding the role of agrochemical giants Bayer and Syngenta in the United Kingdom (UK)’s recent decision to temporarily allow the use of neonicotinoid seed treatment on oilseed rape crop. A record of the meeting, involving the UK government’s expert committee on pesticides (ECP) and industry representatives, had previously been suppressed. The newly released record of the meeting shows that Bayer and Syngenta were the only external representatives asked to answer the ECP’s questions. The emergency use, which has been granted for 120 days, allows growers to use Bayer’s Modesto (clothianidin) and Syngenta’s Cruiser OSR (thiamethoxam). The active ingredients of these products belong to a class of toxic chemicals known as neonicotinoids  (neonics), which have been  linked  to pollinator decline. These pesticides are associated with  decreased learning,  foraging  and navigational ability in bees, as well as increased vulnerability to pathogens and parasites as a result of suppressed bee immune systems. Used widely in agriculture as seed treatment for various crops, foraging bees, in the absence of their native habitat, are exposed to fields of poison where even pollen and nectar are contaminated. In addition to toxicity to bees, neonicotinoids have been shown […]
