background:  scabies is an ectoparasitic infection, which occurs because of direct skin-to skin contact. the ideal treatment modality is still unclear and further research on this topic is warranted. the aim of the study was to com­pare the efficacy and safety of the topical scabicides: permethrin, crotamiton and sulfur ointment. methods: fifty four patients with diagnosed scabies were randomly...

The expression of some insect P450 genes can be induced by both exogenous and endogenous compounds and there is evidence to suggest that multiple constitutively overexpressed P450 genes are co-responsible for the development of resistance to permethrin in resistant mosquitoes. This study characterized the permethrin induction profiles of P450 genes known to be constitutively overexpressed in re...

To determine cypermethrin and permethrin in agricultural products, a competitive enzyme-linked immunosorbent assay (ELISA) method was employed. The matrix interferences were minimized by direct dilution of the extracts. No further cleanup was needed. A minimum matrix effect with a 1:10 dilution of white wine for cypermethrin and a 1:200 dilution of red and white wines, fruits, and vegetables fo...

J. Econ.Entomol.76: 987-989 (1983) ABSTRACT Cultures of Trichoplusia ni (HUbner), collected during 1980 from II eastern states and California, were assessed for susceptibility to methomyl and permethrin. T. ni were more susceptible to permethrin than methomyl, and the ratio of LD", values (methomylto permethrin) within each location ranged from 28:1 to 691:1. LDsovalues for permethrin varied by...

Radiocarbon from I4C-acidand 14C-alcohol-labeled preparations of transand cis-permethrin administered orally to lactating Jersey cows for three consecutive days at 1.0 mg/kg is largely eliminated from the body within 12 or 13 days after the initial treatment. Milk and fat residues, although relatively low, are higher with cisthan with trans-permethrin and consist almost entirely of unmetabolize...

background: aquatic ecosystems are frequently subjected to contamination by toxic heavy metals and pesticides, yet very little is known about the influence of pesticides on bioaccumulation of heavy metals in aquatic organisms. mercury is a toxic metal with no known biological benefit to organisms. bioavailability of mercury in aquatic environments depends on biological and non-biological parame...

Objectives To assess the effectiveness of nanopermethrin as a potential new formulation for pest and vector control. Methods Permethrin nanoparticles were prepared by ionic gelation method its structure formulations designed using Box–Behnken statistical technique. The effect independent variables (Chitosan/Permethrin ratio, tripolyphosphate quantity, sonication time) on properties was investig...

BACKGROUND A previous study indicated that a single application of 4% dimeticone liquid gel was effective in treating head louse infestation. This study was designed to confirm this in comparison with two applications of 1% permethrin. METHODS We have performed a single centre parallel group, randomised, controlled, open label, community based trial, with domiciliary visits, in Cambridgeshire...

control of insect pests of agriculture, economic, and medical importance usually focuses on the use of insecticides. the susceptibility levels of eleven strains of german cockroaches, blattella germanica (l.), were compared with a standard susceptible strain against permethrin and fipronil. the strains were collected from nine infested students’ dormitories and two infested hospitals in tehran,...
