N2 - A UV-resistant mutant (Bt-m) of Bacillus thuringiensis subsp. kurstaki, producing a dark brown pigment, identified as melanin, was studied. Bt-m had higher larvicidity against Heliothis armigera than its parent. Survival of Bt-m spores and their insecticidal activity to irradiation at 254 nm and 366 nm were higher than those of the parent. The only toxic polypeptide produced by Bt-m was Cry1Ac (130 kDa); it lost cry1Aa, cry2Aa, and cry2Ab.
