ABSTRACT

The parasitoid composition of the soybean cutworm (Spodoptera litura F.) in Hanoi and surrounding areas between 1996-1997 was found to consist of 6 species. Among them were 4 species of Hymenoptera and 2 species of Diptera. Microplitis prodeniae Rao et Chadry is the most important species that can regulate the soybean cutworms. The larva] instar suitability of the host (S. litura) for the parasitoid Microplitis prodeniae is from the first instar to the first day of the fifth instar, with the first larval instar being less suitable. The larval instars preferred by M. prodeniae are L, -L3 as compared to Lj and L4. M. prodeniae does not select L5 of host to lay its egg if given a choice. Food quality exerts an obvious effect on M. prodeniae longevity and reproductive capacity. Honey and 50% sugar solution seems to be the best food where the females lived longer and parasitic efficiency increased. The larvae of the parasitoid significantly affected the host's larval development. The duration of development of one instar of the parasited larval host was longer (2-4 times) as compared to the unparasited larvae.


Key words: soybean cutworm, Spodoptera litura, insect parasite, Microplitis prodeniae, Vietnam
