Abstract
Drino munda (Wiedemann), an import from India, successfully parasitized half-grown (or larger) larvae of both the corn earworm, Heliothis zea (Boddie), and the fall armyworm, Spodoptera frugiperda (J. E. Smith). Younger host larvae, if attacked, usually died before the parasites could complete their development. Females of D. munda had a preoviposition period averaging 8.5 days, then laid up to 36 eggs each (average 19) during a 5-day oviposition period. Lengths of the larval and pupal stages averaged 4 and 9 days, respectively, on the corn earworm; 6 and 11 days, respectively, on the fall army worm. Adult longevity averaged 19 days. A technique for mass rearing D. munda is described.
