Objectives Indoor residual spraying (IRS) with insecticides is the main vector control intervention for elimination of visceral leishmaniasis in India. After a change IRS policy 2015 due to widespread resistance Phlebotomus argentipes DDT, DDT was replaced alpha-cypermethrin 2016. The objective present study evaluate susceptibility P. and its alternatives, namely malathion pirimiphos-methyl (or...

anopheles stephensi is an important malaria vector in southern iran. this species developed resistance to ddt in 1975 and subsequently to dieldrin in 1960. since 1968 this species has been under pressure of malathin house sprayin. 50% w.d.p. , 2g/m2, 1-2 rounds per year. susceptibility tests carried out with malathion impregnated papers during 1979 showed that an.stephensi has acquired resistan...

The lesser mealworm (LMW, Alphitobius diaperinus (Panzer); Coleoptera: Tenebrionidae) is increasingly used as a novel food and feed source. materials on which this insect species reared may contain residues of insecticides from agricultural use. objective study was to determine whether selected insecticides, spiked the substrate, could bioaccumulate in LMW and/or affect growth or survival. Inse...

To understand better the mode of action of insecticides and repellents used in vector-borne diseases control, we developed a new biological model based on mosquito neurons isolated from adults Anopheles gambiae heads. This cellular model is well adapted to multidisciplinary approaches: electrophysiology, pharmacology, molecular biology and biochemical assays. Using RT-PCR, we demonstrated that ...

BACKGROUND & OBJECTIVES Interest in insect glutathione s-transferases (GSTs) has primarily focused on their role in insecticide resistance. These play an important role in biotransformation and detoxification of many different xenobiotic and endogenous substances including insecticides. The GST activity among 10 laboratory selected insecticide resistant and susceptible/control strains of Anophe...
