Abstract
Primary powder of Bacillus sphaericus strain 1593 was applied to natural breeding sites of mosquitoes at Nsukka, Nigeria, at doses of a laboratory-determined LC 100, 2 × LC 100, and 4 × LC 100. The predominant larvae were Anopheles spp., potential vectors of malarial parasites, and Culex spp., potential vectors of parasites of filariasis and mosquito-borne encephalitis. Populations of Culex and other types of mosquito larvae were controlled with a 2 × LC 100 dose while Anopheles larvae were controlled with a 4 × LC 100 dose. Mortality in the caged larvae and larval reduction in the field indicated that the powder was more effective against the larvae of Culex spp. than Anopheles spp.
