  • Chemicals Implicated in Colony Collapse Disorder
    Chemicals Implicated While research is underway to determine the cause of Colony Collapse Disorder (CCD), pesticides have emerged as one of the prime suspects. Recent bans in Europe attest to the growing concerns surrounding pesticide use and honeybee decline. Neonicotinoids 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 and thiamethoxam. According to the EPA, uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they relate to pollinators. Studies conducted in the late 1990s suggest that neonicotinic residues can accumulate in pollen and nectar of treated plants and represent a potential risk to pollinators. There is major concern that neonicotinoid pesticides may play a role in recent pollinator declines. Neonicotinoids can also be persistent in the environment, and when used as seed treatments, translocate to residues in pollen and nectar of treated plants. The potential for these residues to affect bees and other pollinators remain uncertain. Despite these uncertainties, neonicotinoids are beginning to dominate the market place, putting pollinators at risk. The case of the neonicotinoids exemplifies two critical problems with current registration procedures and risk assessment methods for pesticides: the reliance on industry-funded science that contradicts peer-reviewed studies and the insufficiency of current risk assessment procedures to account for sublethal effects of pesticides. • Imidacloprid Used in agriculture as foliar and seed treatments, for indoor and outdoor insect control, home gardening and pet products, imidacloprid is the most popular neonicotinoid, first registered in 1994 under the trade names Merit®, Admire®, Advantage TM.

  • Historical Use of Lead Arsenate and Survey of Soil Residues in Former Apple Orchards in Virginia
    HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA by Therese Nowak Schooley Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN LIFE SCIENCES in Entomology Michael J. Weaver, Chair Donald E. Mullins, Co-Chair Matthew J. Eick May 4, 2006 Blacksburg, Virginia Keywords: arsenic, lead, lead arsenate, orchards, soil residues, historical pesticides HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA Therese Nowak Schooley Abstract Inorganic pesticides including natural chemicals such as arsenic, copper, lead, and sulfur have been used extensively to control pests in agriculture. Lead arsenate (PbHAsO4) was first used in apple orchards in the late 1890’s to combat the codling moth, Cydia pomonella (Linnaeus). The affordable and persistent pesticide was applied in ever increasing amounts for the next half century. The persistence in the environment in addition to the heavy applications during the early 1900’s may have led to many of the current and former orchards in this country being contaminated. In this study, soil samples were taken from several apple orchards across the state, ranging from Southwest to Northern Virginia and were analyzed for arsenic and lead. Based on naturally occurring background levels and standards set by other states, two orchards sampled in this study were found to have very high levels of arsenic and lead in the soil, Snead Farm and Mint Spring Recreational Park. Average arsenic levels at Mint Spring Recreational Park and Snead Farm were found to be 65.2 ppm and 107.6 ppm, respectively.

Now we under- stand there are better methods and products that really work” Environmental Health Watch Did you know...? ■ Many pesticides for home use are toxic? ■ There are alternative pest management methods that limit the use of toxic substances? ■ Mice, cockroaches, and cockroach "dust” can trigger asthma attack? What is it? Integrated pest management (IPM) is a way to remove pests, like cock- roaches, mice, and rats from a home. IPM is a common sense approach that: ■ Denies pests food, water, shelter and a way to enter the home. ■ Uses baits and powders, such as gel baits, traps and borate powder. Why use IPM? ■ IPM is safer. IPM does not use as many harmful pesticides as traditional pest control. - Avoiding pesticides is especially important in homes. Pesticides can contain long lasting, toxic chemicals or lung irritants that cause asthma attacks. Children are among those most vulnerable to exposure. IPM strategies apply pesticides only as needed and use the least hazardous pesticides to control pests. continued on back www.hud.gov/offices/lead U.S. Department of Housing and Urban Development SAFE PEST CONTROL Office of Healthy Homes and Lead Hazard Control Non-toxic traps can be part of an IPM strategy.

  • Who Needs Chlorpyrifos and Why (By Crop)?
    1 WHO NEEDS CHLORPYRIFOS AND WHY (BY CROP)? EXCERPTS OF COMMENTS SUBMITTED TO EPA AT EPA-HQ-OPP-2015-0653 GENERAL “Consumers I have visited with that do not have any ag background are easily swayed into the belief that farmers are polluting the environment and recklessly applying chemicals. Truth is our farmers are professionals and with today’s pricing cannot afford to be over- or misapplying inputs that affect their bottom lines…. I strongly suggest that you…allow producers of the world’s food source to continue using the product chlorpyrifos.” – North Dakota farmer. “Many food crop industries in the Pacific Northwest are concerned about the impacts to pest management based on EPA’s proposed tolerance revocation of chlorpyrifos, including several minor crop groups with limited pesticide options. These industries include processed vegetables, strawberry, grass seed, mint, and cranberry. For many of these industries, chlorpyrifos has unique properties that make it an essential part of their Integrated Pest Management program. It is also an important tool for resistance management. Several of these industries have conducted research to identify effective alternatives to chlorpyrifos, but currently there aren’t viable alternatives that match the efficacy and low risk of this product for managing a number of critical pests…. A revocation of all chlorpyrifos tolerances would eliminate a number of low-risk, critical uses in cases where few alternatives exist at present, and in many cases those alternatives (neonicotinoids, pyrethroids) would be less efficacious, more expensive and have greater impacts on nontarget species including pollinators and beneficial insects. Further, the economic impacts based on resulting crop damage would be substantial.” – Oregon State University Agronomist.

  • Chlorpyrifos, Part 1: Toxicology
    JOURNAL OF PESTICIDE REFORM/ WINTER 1994 • VOL.14, NO. 4 ■ INSECTICIDE FACTSHEET CHLORPYRIFOS, PART 1: TOXICOLOGY The broad spectrum organophosphate insecticide chlorpyrifos is the most widely used insecticide in the U.S. Total use is estimated at almost 30 million pounds per year. Like all organophosphate insecticides, chlorpyrifos affects the nervous system by inhibiting an enzyme that is important in the transmission of nerve impulses. Symptoms of acute poisoning include headache, nausea, muscle twitching, and convulsions. Chlorpyrifos poisonings are reported to state and federal agencies more often than poisonings of almost every other insecticide. In both laboratory animals and humans, chlorpyrifos can also cause delayed effects on the nervous system. Some effects have been measured years after exposure. Human birth defects have been associated with exposure to chlorpyrifos products. In pregnant laboratory animals, chlorpyrifos exposure caused fetal death. Pups that did survive were smaller pups and did not survive as well as pups from unexposed mothers. Chlorpyrifos also affects the male reproductive system; exposure to a chlorpyrifos product has caused death of cells in male rat testes and a decrease in sperm production in cattle. Chlorpyrifos has caused genetic damage in human blood and lymph cells, mice spleen cells, and hamster bone marrow cells. Immune system abnormalities have been reported from patients exposed to chlorpyrifos. Many individuals report developing sensitivities to a broad array of substances following chlorpyrifos exposure. The second part of this factsheet will discuss human exposure to chlorpyrifos and the ecological effects of chlorpyrifos.

  • Acute Toxicity of Selected Insecticides and Their Safety to Honey Bee (Apis Mellifera L.) Workers Under Laboratory Conditions
    Open Access Austin Environmental Sciences Special Article - Pesticides Acute Toxicity of Selected Insecticides and Their Safety to Honey Bee (Apis mellifera L.) Workers Under Laboratory Conditions Abbassy MA1*, Nasr HM1, Abo-yousef HM2 and Dawood RR1 Abstract 1 Department of Plant Protection, Damanhur University, Objectives: The honey bee, Apis mellifera L., is widely used for the Egypt production of honey, wax, pollen, propolis, royal jelly and venom and crop 2Central Laboratory of Pesticides, Ministry of Agriculture pollination. Since honey bees can be exposed to insecticides in sprayed flowering and Land Reclamation, Egypt crops, therefore, this study aimed to assess the acute toxicity and safety index *Corresponding author: Moustafa A Abbassy, of five commonly used insecticides to honey bee workers in laboratory. Department of Plant Protection, Damanhur University, Methods: Bees were exposed to the insecticides: Imidacloprid, Pesticide Chemistry and Toxicology, Egypt Thiamethoxam, Esfenvalerate, Indoxacarb and Chlorantraniliprole by two Received: May 03, 2020; Accepted: May 25, 2020; methods of exposure: topical application and feeding techniques. LD50 and LC50 Published: June 01, 2020 values for each insecticide to honey bees were determined after 24 and 48 h from treatment. Results: The LD50 values in µg per bee were 0.0018 (indoxacarb), 0.019 (esfenvalerate), 0.024 (thiamethoxam), 0.029 (imidacloprid) and 107.12 -1 (chlorantraniliprole). The LC50 values (mg L ), for each insecticide, were as follows: indoxacarb, 0.091; esfenvalerate, 0.014; thiamethoxam, 0.009; imidacloprid, 0.003 and chlorantraniliprole, 0.026, after 24 h from exposure. In general, the neonicotinoid insecticides were the most toxic to bees by feeding technique, and indoxacarb, esfenvalerate were the most toxic by contact method while chlorantraniliprole had slightly or non- toxic effect by the two methods.
