Abstract

Henosepilachna vigintioctomaculata (Motschulsky) (Coleoptera: Coccinellidae), important pests of agricultural crops in Korea, including eggplant and potato, were collected in the Kyonggido area each summer from 1983 to 1986. Data were recorded for rates of parasitism against each host stage and seasonal activity. The parasitoids NothoserPhus afissae (Watanabe), (Hymenoptera: Proctotrupidae), Uga menoni (Kerrich), (Hymenoptera: Cha1cididae), and Pediobius foveolatus (Crawford), (Hymenoptera: Eulophidae) were reared from the host insects. A solitary larval parasitoid, N. afissae, was reared from 2nd to 4th instar brval hosts, with parasitism being highest in the 3rd instar collection. U. menoni, a solitary larval-pupal parasitoid, was reared from 3rd instar larvae to pupae, and parasitism was highest in the pupal collection. N. afissae and U. menoni occurred during June to September. N. afissae showed relatively high parasitism during the entire study period as compared with other species, while parasitization by U. menoni was highest in July. P. foveolatus, a gregarious larval parasitoid, did not generally appear until September, although it appeared in early August in the southern part of Korea. The number of P. foveolatus emerging from a mummy varied, ranging from 7 to 26 (mean = 13. 8).
