Evaluation of Fluralaner and Afoxolaner Treatments to Control Flea
Dryden et al. Parasites & Vectors (2016) 9:365 DOI 10.1186/s13071-016-1654-7 RESEARCH Open Access Evaluation of fluralaner and afoxolaner treatments to control flea populations, reduce pruritus and minimize dermatologic lesions in naturally infested dogs in private residences in west central Florida USA Michael W. Dryden1*, Michael S. Canfield2, Kimberly Kalosy1, Amber Smith1, Lisa Crevoiserat1, Jennifer C. McGrady1, Kaitlin M. Foley1, Kathryn Green2, Chantelle Tebaldi2, Vicki Smith1, Tashina Bennett1, Kathleen Heaney3, Lisa Math3, Christine Royal3 and Fangshi Sun3 Abstract Background: A study was conducted to evaluate and compare the effectiveness of two different oral flea and tick products to control flea infestations, reduce pruritus and minimize dermatologic lesions over a 12 week period on naturally infested dogs in west central FL USA. Methods: Thirty-four dogs with natural flea infestations living in 17 homes were treated once with a fluralaner chew on study day 0. Another 27 dogs living in 17 different homes were treated orally with an afoxolaner chewable on day 0, once between days 28–30 and once again between days 54–60. All products were administered according to label directions by study investigators. Flea populations on pets were assessed using visual area counts and premise flea infestations were assessed using intermittent-light flea traps on days 0, 7, 14, 21, and once between days 28–30, 40–45, 54–60 and 82–86. Dermatologic assessments were conducted on day 0 and once monthly. Pruritus assessments were conducted by owners throughout the study. No concurrent treatments for existing skin disease (antibiotics, anti-inflammatories, anti-fungals) were allowed. -
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. -

Stout, Jeff Davis, Rodrigo Diaz and Julien M. Beuzelin Received: 2 February 2017; Accepted: 2 May 2017; Published: 9 May 2017 Abstract: This study investigated alternative in-field chemical controls against Bactrocera tryoni (Froggatt). Bioassay 1 tested the mortality of adults exposed to fruit and filter paper dipped in insecticide, and the topical application of insecticide to adults/fruit. Bioassay 2 measured the mortality of adults permitted to oviposit on fruit dipped in insecticide and aged 0, 1, 3, or 5 days, plus the production of offspring. Bioassay 3 tested infested fruit sprayed with insecticide. The field bioassay trialed the mortality of adults exposed to one- and five-day insecticide residues on peaches, and subsequent offspring. Abamectin, alpha-cypermethrin, clothianidin, dimethoate (half-label rate), emamectin benzoate, fenthion (half- and full-label rate), and trichlorfon were the most efficacious in bioassay 1, across 18 tested insecticide treatments. -
Immunosuppression in Honeybee Queens by the Neonicotinoids Thiacloprid and Clothianidin
www.nature.com/scientificreports OPEN Immunosuppression in Honeybee Queens by the Neonicotinoids Thiacloprid and Clothianidin Received: 24 November 2016 Annely Brandt1, Katharina Grikscheit2, Reinhold Siede1, Robert Grosse2, Marina Doris Accepted: 19 May 2017 Meixner 1 & Ralph Büchler1 Published: xx xx xxxx Queen health is crucial to colony survival of honeybees, since reproduction and colony growth rely solely on the queen. Queen failure is considered a relevant cause of colony losses, yet few data exist concerning effects of environmental stressors on queens. Here we demonstrate for the first time that exposure to field-realistic concentrations of neonicotinoid pesticides can severely affect the immunocompetence of queens of western honeybees (Apis mellifera L.). In young queens exposed to thiacloprid (200 µg/l or 2000 µg/l) or clothianidin (10 µg/l or 50 µg/l), the total hemocyte number and the proportion of active, differentiated hemocytes was significantly reduced. Moreover, functional aspects of the immune defence namely the wound healing/melanisation response, as well as the antimicrobial activity of the hemolymph were impaired. Our results demonstrate that neonicotinoid insecticides can negatively affect the immunocompetence of queens, possibly leading to an impaired disease resistance capacity. Honeybees are highly eusocial insects that build colonies of several thousand individuals which contain only one fertile female, the queen1. This queen is responsible for all egg laying and brood production within the colony; consequently, her integrity and health is crucial for the colony’s performance and survival, and any impairment can result in adverse effects on colony fitness. In the worst case, if the workers are unable to replace a failing queen, the colony will perish2–4. -

To optimise crop yield, the cocoa trees require spraying with neonicotinoid insecticides (Imidacloprid, Thiacloprid Acetamiprid and Thiamethoxam). It is proposed that rainwater runoff from the treated area may pollute the Owena River and that these pesticides may thereby enter the human food chain via six species of fish (Clarias gariepinus, Clarias anguillaris, Sarotherodon galilaeus, Parachanna obscura, Oreochromis niloticus and Gymnarchus niloticus) which are cultured in the river mostly for local consumption. -

(DICTYOPTERA: BLATTELLIDAE) By FATMA SHERIF AHMED B.Sc. Agric. Sci. (Pesticides), Fac. Agric., Cairo Univ., 2007 THESIS Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE In Agricultural Sciences (Pesticides) Department of Economic Entomology and Pesticides Faculty of Agriculture Cairo University EGYPT 2015 ١ INTRODUCTION The German cockroaches, Blattellagermanica (L.), (Dictyoptera, Blattellidae) are the most common indoor pests, especially in multiple-family housing and the most significant pest in many parts of the world (Goddard, 2003). German cockroaches prefer warm, wet locations with high humidity such as kitchens, bathrooms and laundry areas. These conditions are available in several places as homes, apartments, restaurants, supermarkets, hospitals and other buildings where food are stored. Cockroaches are not only corrupt food but also transfer pathogens such as Salmonella, Shigella, Escherichia coli, Staphylococcus aureus and Bacillus cereus (Baumholtz et al., 1997 and Tachbeleet al., 2006). Medically important parasites such as bacteria, fungi and molds, protozoans, viruses were isolated from external and internal surface of cockroach (Brenner, 1995). Cockroaches can also transfer both gram-positive and negative bacteria (El-Sherbini and El- Sherbini, 2011). A large number of neurotoxic and non-neurotoxic insecticides were used for German cockroach control, as this pest has a considerable ability to develop resistance to a variety of chemical insecticides(Cochran, 1989 and 1995a; Scott et al., 1990; Rust and Reierson, 1991; Rust et al., 1993; Holbrook et al., 1999; Espinosa-Islas et al., 2002 and Rahayuet al., 2012).
