Abstract

The striped mealybug, Ferrista virgata (Ckll.) has become a very serious pest of guava in India. Since the insecticides are ineffective, an attempt was made to suppress F. virgata with an introduced coccinellid, Cryptolaemus montrouzieri Mulsant C. montrouzieri and other local natural enemies especially Aenasius advena Comp. and Scymnus coccivora Ayyar effectively controlled F. virgata in guava orchards.
