Abstract
Trathala flavoorbitalis, a larval and pupal parasitoid of eggplant fruit and shoot borer (FSB) is widely available in eggplant fields. It is dependent on its host density. It is population can increase about 10-fold and parasitism rate about three-fold in a year if insecticide use in eggplant fields is avoided. The development period from egg laying to adult emergence is about 16 days and it is a uniparental type of parasitoid, which produces about 98% females. Greenhouse and micro-plot tests have shown that the parasitoid is highly efficient in controlling the FSB infestation, amounting to about 90% parasitism in greenhouse and 70% in micro-plot tests.
