Abstract To tackle the problem of insecticide resistance, all resistance mechanisms need to be studied. This study investigated involvement cuticle in pyrethroid a strain Anopheles gambiae , MRS, free kdr mutations. Bioassays revealed MRS resistant pyrethroids and DDT, indicated by increasing knockdown times ratios. Moreover, biochemical analysis that metabolic based on enhanced CYP450 activity may also play role. Insecticide penetration assays showed there were significantly lower amounts...
Abstract Urban Aedes mosquitoes are vectors of many viruses affecting human health such as dengue, chikungunya and Zika viruses. Insecticide resistance environmental toxicity risks hamper the effectiveness chemical control against these mosquito vectors. Alternative methods, use mosquito-specific entomopathogenic should be explored. Numerous studies have focused on evaluating potential different densoviruses species biological agents. However, knowledge extent inter- intra-specific...
Bacillus thuringiensis δ-endotoxins are the most widely used biopesticides for controlling economically important crop pests and disease vectors. Improving their efficacy is of great benefit. Here, an improvement in Cry2Aa δ-endotoxin toxicity was attempted via a cry gene over expression system using P20 from B. israelensis.The coexpression with resulted seven fold increase its production yield thuringiensis. Generated crystals proved to be significantly more toxic (505.207 µg g-1 , 1.99 mg...
Abstract The management of mosquito resistance to chemical insecticides and the biting behaviour some species are motivating search for complementary and/or alternative control methods. use plants is increasingly considered as a sustainable biological solution vector control. aim this study was evaluate effects essential oil (EO) Lippia alba harvested in Abidjan (Côte d’Ivoire) against Anopheles gambiae Aedes aegypti mosquitoes. Phytochemical compounds were identified by GC–MS. Knockdown...
Bacillus thuringiensis (Bt) is a Gram-positive soil bacterium that has been recognized as an effective bioinsecticide active against plant, animal and human pathogenic disease vector insects. During its sporulation phase, Bt produces crystals consisting of δ-endotoxins, which upon ingestion kill specifically insect larvae. subsp. israelensis (Bti) very dipteran Bti based bioinsecticides are considered sustainable solution to control the Dipteran insects responsible diseases. In this study,...
