The effects of Bt Berliner (Dipel�WP and Biotrol� XK, WP) on a tobacco budworm parasitoid, Cardiochiles nigriceps, was determined in laboratory studies. A significant decrease in post-treatment longevity occurred after ingestion of Bt, but no decrease was observed after topical treatment.
This study did not use transgenic plant material.
