Isi artikel

Nine isolates of Bacillus thuringiensis of North Sumatera have been isolated from soil and dead larvae of Plutella xylostella. Bioassay of these isolates to larva of Heliothis armigera, Plutella xylostella, Aedes aegypty, and Culex sp. showed that the isolates have different spectrum and ability in controlling insect larvae. Interestingly, TU1 has similar ability to that of Dipel (B. thuringiensis var kurstaki strain HD-7) in controlling Dipteran (A. eagypti and Culex sp.) and Lepidopteran (H. armigea amd P. xylostella). The others were not effective to Dipteran, but have various abilities to kill Lepidopteran. This result indicated that local isolates of B. thuringiensis of North Sumatra were varied in ability to kill different larvae.
