Summary

A strain of Bacillus thuringiensis isolated from a soil sample in Pondicherry was examined for its flagellar antigenicity, mosquito larvicidal activity and protein composition.This strian was found to agglutinate with the antisera belonging to B.t.thomsoni and exhibit high toxicity towards the larvae of the species of Culex quinquefasiatus, C.tritaeniorhynchus, C.sitiens, Anopheles stephensi, Aedes aegypti respectively. The 28 kDa protein which has been repoted to be perdominantly present in the mosquitocidal strains of B.thuringiensis was found to be present in a higher amount in this strain. Also, the mosquito larvicidal activity and electrophoretic profile were comparable to that of a strain of B.t. var. israelensis which is known to be highly toxic to mosquitoes.
