Effect of larval parasitoid, Bracon greeni Ashmead on Eublemma amabilis, the lepidopteran predator on lac insect, Kerria lacca Kerr.

摘要

The larval parasitoid, Bracon greeni, was evaluated in lac culture against the lepidopteran lac insect predator, Eublemma amabilis (Lepidoptera: Noctuidae). Results indicated that the suppression in the population of E. amabilis was significant only at higher doses 100 and 120 larval parasitoids/tree, inferring that B. greeni can be successfully exploited in lac ecosystem for the effective management of E. amabilis, a major lac insect predator. Besides, the extensive use of this larval parasitoid can reduce the load of chemical pesticides in lac ecosystem.
