  • 9 Accesses

Abstract

A strain ofBacillus thuringiensis Berliner effective against fourth-instarBoarmk selenaria Schiffermüller (Lepidoptera: Geometridae) was found. Strain HD-251 of the varietykurstaki H-serotype 3a, 3b was more effective than the standard HD-1-S-1980 in laboratory bioassays. The potency of HD-251 is two to four times higher than that of the standard, and varies from 19,821 to 68,645 IU/mg. Two other strains of the varietyaizawai H-serotype 7,viz., HD-249 and T63L4, were inferior to HD-251, with potencies of 6,982 and 13,714 IU/mg, respectively, against first-instar larvae.
