Eggs or larvae of Chrysojm carnea Stephens were released on cotton in the field and in field cages to control the bollworm, Heliothis zea (Boddie), and the tobacco budworm, Heliothis virescells (F.). Two field releases totaling 292,000 C. carnea larvae per acre reduced populations as much as 96% and increased yield 3-fold. Releases of C. carnea eggs in field cages at rates of 50,000 and 100,000 per acre also provided effective control of the tobacco budworm.
