Abstract

We tested 50 lepidopteran-toxic Bacillus thuringiensis Berliner (Bt) strains with diverse phenotypes for the ability to survive repeated passages through larvae of the gypsy moth, Lymantria dispar (L.), without intervening growth on artificial media. These experiments have revealed a remarkable correlation between the production of urease (22 of 25) by the bacteria and its ability to survive repeated passages through larvae.
