Abstract
Culex pipiens mosquitoes are vectors of diseases such as Filariases in tropics and viruses in temprate and tropics areas. These vectors are controlled by chemicals including organophosphates insecticides. Since 1970 the effectiveness of the chemical control has been reduced by the development of resistance that has been linked to the increase in carboxylesterase activity. Previous studies had shown that the esterase B1 gene was activated 500 times in OP Culex Tem-R strain. A B1 DNA probe was used for the study of the structure and organisation of B1 esterase gene amplification. This will help understanding the mechanism of the B1 amplification, which is the aim of this study.
