A study was carried out in Anand, Gujarat, India, between 1972 and 1975 to develop the biological control of Heliothis armiger (Hb.), a major pest of (in descending order) potato, gram (Cicer arietinum), tomato and lucerne in the area. Trichogramma australicum Gir. was the only parasite reared from H. armiger eggs, and its highest parasitism rate was observed during February (98.2% parasitism in 1973-74 and 84.2% in 1974-75).
