Evaluation of resistance to insecticides in the mosquito larvae of Anopheles gambae Giles and its control by microbial bacterial pathogens
(University of Nairobi,School of Biological Sciences, 1989)It was found that resistance factors of mosquito larvae were near unity for dieldrin, and 2 to 3 times for Malathion at both Ahero and Mwea, and 2 times for DDT at Ahero. These low resistance factors indicated little or ... -
