The study reports a field survey to determine the presence of parasitism on the leaf defoliator Hypocala andremona (Stoll) (Lepidoptera: Noctuidae) eggs, on parsimmon trees by Trichogrammatids. H. andremona eggs were sampled weekly on two branches/10 trees/orchard during the 2000/01 and 2001/02 crop seasons in Londrina, and during 2000/01crop season in Arapongas, PR, Brazil. In laboratory the eggs were isolated in gelatin capsules and maintained under controlled conditions (26 ± 1ºC, 60 ± 10% RH, 14L:10D). Three parasitoid species were identified: Trichogrammatoidea annulata De Santis, Trichogramma pretiosum Riley and Trichogramma bruni Nagaraja. In Arapongas only T. pretiosum was collected. Natural control levels in general were low, but p...
