The effect of crystal toxin from Bt israelensis on eggs and larvae of the ruminant nematode Trichostrongylus colubriformis was determined. Bt israelensis toxins were lethal to eggs and larval viability was dependent on developmental period of eggs prior to Bt israelensis exposure.
This study did not use Bt from transgenic plants.
