Lifetime gains and patterns of accumulation and mobilization of nutrients in females of the synovigenic parasitoid, Diglyphus isaea Walker (Hymenoptera: Eulophidae), as a function of diet

► Diglyphus isaea Walker is an extreme synovigenic parasitoid species, which can utilise both sugars and host fluids for its maintenance and reproduction. ► The cost of reproduction was found in this species, and the efficiency of conversion per host feeding event was calculated. ► There could be lipogenesis from host food in this species, even non-host food, although only to the level that satisfies the demands of maturing eggs.
