Energy transfer efficiency in three hymenopteran egg parasitoids ofHomoeocerus prominulus (Tagus) (Insecta: Heteroptera: Coreidae)

  • S Rajadurai


Energy budgets of the solitary egg parasitoids,Anastatus ramakrishnae (Mani) andTrissolcus sp., and a gregarious egg parasitoid,Xenoencyrtus sp. nearniger Riek on the eggs ofHomoeocerus prominulus have been compared. Energy allocation for consumption, assimilation and metabolism were greater in the gregarious parasitoid than in the solitary parasitoids; on the other hand, higher production efficiency and lower assimilation efficiency were noticed in the solitary parasitoids than in the gregarious parasitoids. The rate of consumption, assimilation, production and metabolism of gregarious and solitary parasitoids have been compared in the light of their reproductive efficiencies.
