From a total of 41 samples, 122 isolates were obtained, yielding a B. thuringiensis index of 0.22. Isolates were assigned to 13 different serovars, with serovar thuringiensis (serotype H1) the most frequently found. Toxicity tests carried out revealed that eight isolates (6.6% out of the total) were active against Tipula oleracea larvae. Serological tests assigned these toxic isolates to serovar thuringiensis. The toxicity found in these isolates against the tipulid was approximately seven times lower than that shown by the standard strain B. thuringiensis ser. israelensis IPS-82. Implication of Cry2A protein in toxic activity is hypothesized.
