Abstract

A good rearing method is one of the keys in successful biological control practices. This also applied on biological control of Spodoptera litura Fabricius (Lepidoptera: Noctuidae). The objective of this study is to observe the development of Microplitis (Snellanius) manilae (Hymenoptera: Braconidae) on S. litura which cultured in the natural diet (host plants) and the artificial diet. This study was conducted with two treatments which were larvae of S. litura fed with natural diet and artificial diet. Each treatment has 10 individuals as replicates. Each larva was placed in a different petri dish along with the adult of M. manilae. The larvae were exposed to adult parasitoids of M. manilae for 24 hr. Then, the larvae were reared until the parasitoid emerged. The results showed that the highest number of parasitization was found in the hosts which were fed on an artificial diet. Whereas, the highest number of parasitoids emerged were found from the hosts which provided with a natural diet. On both diets, more female parasitoids emerged than males. The difference in nutrient content given to host larvae plays a major role in affecting the number of hosts parasitization, the number of emerged parasitoids and the sex ratio of parasitoids.
