none Heliothis armigera (Hb.) is a common polyphagous pest in India, causing maximum damage to several economic crops. Mass-release of three species of egg parasites, one of egg-larval and three of larval parasites during 1977-83 seems to help in control of the pest in Karnataka. Three species of exotic parasites released have been recovered and so show signs of establishment.
