The sustained speed of kill against Dermacentor reticulatus of two topical combinations, one containing fipronil/amitraz/(S)-methoprene and the other, imidacloprid/permethrin, was evaluated in dogs. Two treated groups and one untreated control group of eight adult Beagle dogs each were randomly formed based on pre-infestation rates and bodyweight. Each treatment was administered topically once ...

The purpose of this study was to conduct a survey for the susceptibility of the horn fly, Hematobia irritans (L.), populations to permethrin on dairy cattle from Aguascalientes, Mexico. Samples of populations of horn flies at 25 dairies were exposed to two discriminating doses (2.5 and 6.0 microg/cm2) on permethrin-treated filter papers and the percentage of mortality was compared with that of ...

Ovicidal activity and killing times were evaluated for six pediculicides, using viable eggs and recently fed head lice from infested children. Lice were continuously exposed to the products until death, and elapsed time was recorded. Eggs were immersed for ten minutes, rinsed, and dried. Four synergized pyrethrin products (RID, R&C Shampoo, A-200 Pyrinate Shampoo, A-200 Pyrinate Liquid) killed ...

BACKGROUND Permethrin is a synthetic pyrethroid insecticide widely used in agriculture, in public health, and in many U.S. homes and gardens. OBJECTIVE In this study we evaluated the incidence of cancer among pesticide applicators exposed to permethrin in the Agricultural Health Study (AHS). METHODS A total of 49,093 pesticide applicators were included in this analysis of the AHS, a prospec...

The efficacy of a 65% permethrin spot-on formulation (Defend EXspot, Schering-Plough Animal Health Corp., Union, NJ) against the dog louse, Trichodectes canis de Greer 1778, was studied. Fourteen dogs naturally infested with T. canis were evenly and randomly allocated to treatment with 65% permethrin administered at the label dose rate of 1 or 2 ml per dog or to an untreated control group. Lous...

Ambrosia beetles tunnel into the heartwood of trees where they cultivate and feed upon a symbiotic fungus. We assessed the effectiveness of flood stress for making Cercis canadensis L. and Cornus florida L. trees attractive to attack as part of insecticide and fungicide efficacy trials conducted in Ohio and Virginia. Since female ambrosia beetles will not begin ovipositing until their symbiotic...

Field tests evaluated repellent formulations containing deet in combination with permethrin-impregnated or untreated military uniforms against Aedes taeniorhynchus. No significant difference was determined between repellents in duration of protection whether or not permethrin-treated clothing was worn, but there were differences in efficacy relative to site of application. The head was the site...

Aim: Demodex parasites have been linked to dermatological disorders, especially rosacea, without a proven mechanism. Moreover, some anti-Demodex agents demonstrate dual therapeutic effect related direct on the skin disorder along with decreased number of mites. Despite being considered first-line treatment approach for azelaic acid's efficacy against mites has not investigated. In current study...

A retrospective analysis of all adverse experience reports received by the Australian Pesticides and Veterinary Medicines Authority's Adverse Experience Reporting Program for veterinary medicines since 1995, showed that permethrin toxicity in cats usually occurred after the owner applied a canine permethrin-containing product, typically a spot-on. Cats are also at risk from grooming or being in...
