Abstract

In studies in India at about 22 deg C, the pupal parasite Xanthopimpla stemmator (Thnb.) oviposited in the pupae of Chilo partellus (Swinh.), a pest of sorghum. The adult parasite emerged from the pupal case, killing the host in the process. Ten mated parasite females had an average life-span of 30 days (maximum 37 days and minimum 22 days). The number of progeny produced ranged from 71 to 115, with an average of 84.5. The male:female ratio of their progeny averaged 1.14:1. The maximum mean progeny production per day (mx) was 1.9. The innate capacity for increase was 0.131 per female per day, and the population multiplied 43.43 times in a generation time of 28.78 days.
