Little is known about the environmental fate or impact of pesticides used to control companion animal parasites. Using data from Environment Agency, we examined occurrence fipronil, fipronil metabolites and imidacloprid in 20 English rivers 2016 2018, as indicators potential contamination waterways their use ectoparasiticides on pets. Water samples were collected by Agency part chemical surveil...

The toxicity and horizontal transfer of a new formulation of fipronil, 0.5% fipronil dust, was tested against Coptotermes formosanus Shiraki in the laboratory. The formulation was applied in three different ways: 1) Directly applied to termites (donors) and mixed with untreated termites (recipients) at three ratios, viz., 50 donors: 50 recipients, 20 donors: 80 recipients and 10 donors: 90 reci...

BACKGROUND Visceral leishmaniasis (VL) is a disease caused by two known vector-borne parasite species (Leishmania donovani, L. infantum), transmitted to man by phlebotomine sand flies (species: Phlebotomus and Lutzomyia), resulting in ≈50,000 human fatalities annually, ≈67% occurring on the Indian subcontinent. Indoor residual spraying is the current method of sand fly control in India, but alt...

A gel bait-resistant Blattella germanica (L.) strain (Cincy) was collected in Cincinnati, OH, in 2003. This strain exhibited strong behavioral resistance to Avert (0.05% abamectin), Maxforce FC (0.01% fipronil), and Pre-Empt (2.15% imidacloprid) gel baits. Reciprocal mass crosses and back crosses between the Cincy strain and a susceptible strain (Jwax) were made and tested for their inheritance...

Fipronil is a broad-spectrum insecticide whose release in the environment damages many non-target organisms. This study evaluated toxicity of fipronil at two biological levels using vivo conditions and environmentally relevant concentrations: first based on model organisms (aquatic invertebrate Daphnia magna unicellular freshwater alga Chlamydomonas reinhardtii) second three natural communities...

This study was conducted to assess the prevention of egg laying and the inhibition of the emergence of the cat flea (Ctenocephalides felis) resulting from the application of a combination of fipronil and permethrin (Frontline Tri-Act®/Frontect®, Merial) on dogs. Sixteen healthy dogs were included after pre-treatment live flea counts and randomly allocated to two groups. Eight dogs served as unt...

La muerte masiva de abejas y otros insectos polinizadores por el uso indiscriminado las moléculas clotianidina, tiametoxam, imidacloprid fipronil en Colombia llevó a su protección mediante decisión judicial, situación que constituye un importante precedente la defensa especies amenazadas no controlado este tipo sustancias aplicación del principio precaución.

Zusammenfassung Ziel dieser Arbeit ist die Beschreibung der Entwicklung einer webbasierten, interaktiven Darstellung von maximalen tolerierbaren Verzehrmengen für ausgewählte Lebensmittel, beispielsweise in Ereignissituation als potenziell kontaminiert angenommen werden („Kontaminantenrechner“). Die vorliegende beschreibt einen Katalog wissenschaftlicher Anwendungskriterien solchen Kontaminante...

Insecticide susceptibility and virulence to resistant rice varieties were determined and evaluated in the brown planthopper (BPH) and the whitebacked planthopper (WBPH), collected from Asian countries (Japan, China, Taiwan, northern Vietnam, southern Vietnam, and Philippines) in 2006. Insecticide susceptibility was determined by a topical application method using four insecticides. Virulence to...
