Trichogramma zahiri (Hymenoptera: Trichogrammatidae) an egg parasitoid of the rice hispa Dicladispa armigera (Coleoptera: Chrysomelidae) in Bangladesh

Abstract

Trichogramma zahiri Polaszek sp. n. is described from Bangladesh. It has been collected at several localities from the major pest of rice Dicladispa armigera (Olivier) on which it has an important controlling impact. Trichogramma zahiri is compared with known Trichogramma species from the region, and diagnostic differences are presented. Data on developmental period, adult longevity, egg-laying frequency, host egg age preference and seasonal parasitism rate are presented and discussed. Other records of parasitoids of D. armigera are briefly reviewed and discussed.
