In the present study, the potential hazard of Bacillus thuringiensis (Bt) kurstaki HD1 spore-crystal mixture (spore/-endotoxin) on parasitization performance and longevity of female egg parasitoid Trichogramma evanescens Westwood was evaluated. For this purpose, Bt kurstaki HD1 was incubated at 30 degrees C in T3 medium at 200 rpm for seven days. Lyophilized spore-crystal mixture (5000 mu g mL(-1)) was mixed with 50% honey solution and supplied to 0-24 h old T. evanescens adults as a nutrient to ensure the ingestion of the toxins by the parasitoids. The results indicated that spore-crystal mixture of Bacillus thuringiensis subsp. kurstaki (Btk) HD1 did not induce considerable decrease in parasitization performance and longevity of T. evanescens adults. Thus, it can be concluded that Btk HD1 products can safely be used together with egg parasitoid T. evanescens in integrated pest management system to compensate the deficiency of each control tactic alone.
