Lambdacyhalothrin (LCT) is a pyrethroid insecticide class, which is widely used for pest control in agriculture, public health, home and garden. In the present study we investigated the effect of long term exposure of low doses of the LCT on the state of lipid peroxidation and antioxidant protection of pregnant rats and their offspring. It was revealed, that prolonged exposure of lambdacyhaloth...
J. Agric. Entomol. l(}(3):197-203 (July 1993) ABSTRACT Based on data from apple trees without the presence of any predatory mites, the effect of the pyrethroid lambdacyhalothrin on population density of the twospotted spider mite, Tetranychus urticae Koch, is reported. Results show that significantly (P < 0.05) higher numbers of T. urticae were found in pyrethroid·treatcd trees relative to the ...
OBJECTIVE The aim of the study was to monitor the insecticide susceptibility status of malaria vectors in 12 sentinel districts of Tanzania. METHODS WHO standard methods were used to detect knock-down and mortality in the wild female Anopheles mosquitoes collected in sentinel districts. The WHO diagnostic doses of 0.05% deltamethrin, 0.05% lambdacyhalothrin, 0.75% permethrin and 4% DDT were u...
Insecticide susceptibility tests were conducted on five mosquito species collected from two localities in the Jordan Valley (Deir Alla and Ghor as Safi) in 2014. Diagnostic concentration of Temephos (0.25mg/L) was used against the larvae, while diagnostic concentrations of Deltamethrin (0.025%) and Lambdacyhalothrin (0.03g/m2) were used against the adults. The procedures of WHO were followed. A...
The efficacy of synthetic pyrethroid-impregnated fabrics was evaluated against Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus, under laboratory conditions. Results revealed that delta-methrin was significantly superior in comparison to lambdacyhalothrin and cyfluthrin. Results of bioassay tests revealed that deltamethrin was 1.5 and 1.9 times more effective than lambdacyhalothri...
The present study aimed to determine the selectivity of the pyrethroid lambdacyhalothrin on arthropod natural enemy populations in irrigated rice fields in Rio Grande do Sul, Brazil. The study was conducted at three sites: districts of Cachoeira do Sul, Eldorado do Sul and Capivari do Sul during the crop years of 2007/2008 and 2008/ 2009. Each site consisted of two subareas divided into four pl...
Behavioral responses of two field populations of Anopheles minimus complex species A and C for contact and non-contact actions of chemicals were compared during and after exposure to operational field concentrations of DDT (2 g/m2), deltamethrin (0.02 g/m2), and lambdacyhalothrin (0.03 g/m2) using an excito-repellency escape chamber. The two populations were collected from the Mae Sot District ...
the rational use of insecticides largely depends on a broad knowledge of the susceptibility and irritability levels of malaria vectors to currently used insecticides especially pyrethroids. in this study the susceptibility and irritability levels of anopheles stephensi and an.culicifacies to ddt 4%,malathion 5%, propoxur 0.1%, deltamethrin 0.025%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and per...
