| dc.description.abstract | The populations of Eriborus trochanteratus (Morley) occurring in India and Sri Lanka, are morphologically identical, but belong to two biotypes. A method to rear the Sri Lankan biotype of E. trochanteratus using Opisina arenosella Wlk. as host in the laboratory was developed. Additional information on the mating behaviour, oviposition and life history of the parasitoid on O. arenosella and Corcyra cephalonica caterpillars was collected. Attempts on field colonisation of the laboratory reared parasitoids in Opisina infested coconut gardens in the West Coast of Kerala resulted in establishment and recovery. However, hyperparasitism by the chalcidid Brachymeria nephantidis Gahan was observed in a few cocoons of E. trochanteratus collected from the release site. The possible reasons for the slow build up of population of E. trochanteratus in the field are also discussed. | en_US |
