A new multicrystalliferous Bacillus thuringiensis isolate from diseased mosquito larvae

A new multicrystalliferous Bacillus thuringiensis isolate from diseased mosquito larvae

Current Science 51(16): 794-795

A pathogen lethal to laboratory colonies of Culex quinquefasciatus Say (fatigans Wied.) in Bombay, India, was identified as Bacillus thuringiensis subsp. kurstaki, and its physical and chemical properties are described. The LC50s were found to be 1.91 X 105 spores/ml for 2nd-instar larvae and 1.9 X 105 spores/ml for 3rd-instar larvae.
