The interaction between the insect pest, Agrotis ypsilon; the parasite, Apanteles ruficrus and the pathogen Bacillus thuringiensis has been investigated. A. ruficrus parasitizing on host larvae treated with B. thuringiensis showed significant reduction in the egg production, formed cocoons, longevity of either sex and emerged adults. The mortalities caused by B-exotoxin were increased among parasitized host larvae more than the unparasitized ones.
