Field evaluation of Bacillus sphaericus, H5a5b and B. thuringiensis var. israelensis, H-14 against the Bancroftian filariasis vector Culex quinquefasciatus, Say in Chennai, India.
Fortnightly application of Bacillus sphaericus (strain B101, serotype H5a5b) and B. thuringiensis var. israelensis (strain 164, serotype H-14) in two different waterways of Chennai @ 1 g/sq m surface area has resulted in significant reduction in both immature and adult densities of Culex quinquefasciatus Say. The use of these biolarvicides as biocontrol agents is suggested in the urban areas to control mosquitoes in general.
