DDT Resistant Mosquitoes & Where DDT is Still Used

WebIn 1947 the first cases of DDT resistance occurred in Aedes(Brown, 1986). Since then over a hundred species of mosquito have become resistant to one or more insecticide (WHO, 1992). Insecticides used for malaria control have included γ-benzine hexachloride (BHC), organophosphorus, carbamate, and pyrethroid insecticides. WebThe insecticide, DDT, was developed to control disease vectors, such as malaria-carrying mosquitoes. Following widespread use of DDT, mosquito populations became highly resistant to DDT. Scientists believe that DDT resistance first evolved with a mutation in genes coding for sodium ion channels in mosquito neurons. please log in to run this job https://superiortshirt.com
