Abstract

Egg load of teak defoliator, Hyblaea puera Cramer did not reveal any variation among the treatments initially. However, as the time lapsed significant variation was noticed due to increased pest activity. Even larval population differed significantly among the treatments. The parasitoids, Trichogramma chilonis Ishii was not only recovered from the site but gave high percentage of parasitism both on eggs and larvae of H. puera. Among the treatments (T1 with 2 lakhs, T2 -4 lakhs, T3 -6 lakhs, T4 -8 lakhs and T5 – 10 lakhs parasitoids) parasitisation increased as the number of T. chilonis per acre was increased. The treatment receiving less number of T. chilonis had high egg larval population and vice-versa.
