Abstract

Mummification, host selection and biological characteristics of primary parasitoids and hyperparasitoids in the soybean aphid, Aphis glycines, were studied. The soybean aphid mummies which were infected by primary parasitoids or hyherparasitoids were collected at Taejon area from May to September in 1987 Primary parasitoids and hyperparasitoids were emerged 27.1% and 50.3%, from 177 collected mummies. respectively Aphidius cingulatus, Ephedrus persicae and Ephedres plagiator could be effective primary parasitoids against the soybean aphid. Among the hyperparasitoids, Asaphes unlgaris and Ardilea conuexa might be dominant species to primary parasitoids of the soybean aphid. Charips brasicae was recorded for the first time in Korea E.plagiator was less parasitized than any other primary parasitoid by hyperparasitoids. E. plagiator might be higher than A. cingulatus in the ability of prarsitism. Life span of hyperparasitoid and primary parasitoid was estimated to be 3~29 days and 1~4 days, respectively.
