Laboratory studies were conducted to determine the effect of Bacillus thuringiensis Berliner on Cardiochiles nigriceps Viereck, a tobacco budworm parasitoid. Ingestion of the active material in sugar water by this parasitoid resulted in a significant decrease in posttreatment longevity. Topical treatment with B. thuringiensis did not decrease posttreatment longevity, although there did seem to be an initial effect on survival. Wasps exposed to tobacco leaves treated with monocrotophos died within 24 h, but were not affected by exposure to Dipel®-treated leaves. Posttreatment longevity of a stilt bug, Jalysus spinosus (Say), was not decreased by exposure to tobacco leaves treated with B. thuringiensis .
