Abstract

Five hymenopterous egg parasitoids, viz., Trichogramma brasiliensis (Ashmead), T. chilonis Ishii T. pretiosum Riley, Trichogrammatoidea bactrae Nagaraja (Trichogrammatidae) and Telenomus remus Nixon (Scelionidae) were screened against Pseudohypatopa pulverea (Meyr.), a serious predator of lac insect, for assessing their parasitising efficiency. The maximum parasitisation was observed in the case of T. brasiliensis (56.73%) and lowest by T. remus (17.56%). The emergence of the adult parasitoids from the parasitised eggs was maximum in T. petiosum (75.00%) followed by T. chi1onis (72.85%), T. brasi1iensis (66.04%), T. bactrae (34.70%) and lowest by T. remus (43.75%). All the tive parasitoids appeared to be promising for the biological control of the predator.
