A field trial was carried out to study the effect of lambdacyhalothrin on Anopheles maculatus in trap huts in Jeram Kedah, Negeri Sembilan, Malaysia. Two trap huts were built, of which one was sprayed with lambdacyhalothrin at a dosage of 25 mg ai/m2 and the other served as control. Eight collectors commenced collecting mosquitos from 1900 to 2400 hours, two each indoors and outdoors. Bioassay ...

The effect of twelve different groups insecticides on diversity major predators (insects and spiders) during active tillering bootleaf stage rice crop was evaluated in West Bengal. results showed that spinosad, emamectin benzoate, sulfoxaflor pymetrozine were highly safe while buprofezin, imidacloprid, indoxacarb chlorantraniliprole moderately so. like lambdacyhalothrin, fipronil chlorpyriphos ...

Five synthetic pyrethroids, deltamethrin, cypermethrin, permethrin, alpha-cypermethrin, and lambdacyhalothrin, were tested on the larvae of 2 morphological variants of Cx. tritaeniorhynchus collected from Mysore City (ground pools) and outside Mysore (paddy fields), in Karnataka State, India. The morphological characters, ie, length and width of siphon, siphonal index, comb scale numbers, pecte...

susceptibility levels of a lab strain of an. stephensi to who standard papers of ddt 4%, dieldrin 0.4%, malathion 5%, permethrin 0.25%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and deltamethrin 0.025% were determined in our laboratory in 1999. results showed that at the diagnostic dose of insecticides this species exhibited resistance to ddt and dieldrin with mortality rate of 54±2.5% and 30±2.5...

In this work we investigated the inhibitory effect of Deltamethrin, Dichlorvos, Malathion and Lambdacyhalothrin on bovine liver catalase (CAT) activity. We observed that the inhibition of enzyme increased with increasing concentrations of the pesticides from 0 to 250 ppm. The Kinetics conformed to the MichaelisMenten model and a Lineweaver-Burk graph of CAT was drawn. To identify the inhibition...

an investigation was made to study the residual activity and air-borne effect of lambdacyhalothrin (icon 10 wp) at 30, 40 and 50 a.i. mg/rn2 against an.stephensi in hut scale trials on different surfaces in mamasani, and rudan, south of iran. bio-assay contact mortality test with icon at 30 a.i. mgl/m2 on plaster, cement and wood surfaces decreased from 100% to 51.4%, 53% and 63.8% after 84, 80...

BACKGROUND Anopheles mosquitoes are an important group of arthropods due to their role in transmission of malaria. The present study was conducted for determination of susceptibility status of Anopheles stephensi to different imagicides collected from malarious area in Chabahar city, Iran. METHODS In the present study seven insecticides including: DDT 4%, lambdacyhalothrin 0.05%, deltamethrin...

Residues dynamics of Endosulfan (525.00 g a.i. ha(-1)), Imidacloprid seed treatment (21 g a.i. kg(-1)), Lambdacyhalothrin (75.00 g a.i. ha(-1)) and Spiromesifen (225.00 g a.i. ha(-1)) in nectar and pollen of mustard, Brassica juncea (L.) Czern. grown in Himachal Pradesh (India) were determined through bioassay (using Drosophila melanogaster Meig. as test organism) and GC (Gas chromatographic) a...

BACKGROUND AND OBJECTIVES The main rural malaria vector Anopheles culicifacies has developed resistance to dichloro diphenyl trichloroethane (DDT), hexachloro cyclo hexane (HCH) and malathion in the state of Haryana in northern India. An alternative synthetic pyrethroid insecticide bifenthrin was therefore evaluated on mosquito nets against anopheline and culicine mosquitoes, in two villages Ja...

Bioassay tests were carried out to investigate the susceptibility status of two (3rd and 4th) instar larvae of Culex quenquifasciatus Say populations of Dhaka city against two organophosphate (malathion and chloropyrifos) and two pyrithroid (cypermethrin and lambdacyhalothrin) insecticides. The LC50 values of malathion, chloropyrifos, cypermetrin and lambdacyhalothrin against the 3rd instar lar...
