The dormancy characteristics of five Japanese populations of Aphelinus asychis were examined to find strains useful as biological control agents against pest aphids under winter greenhouse conditions in Japan. The weak diapause, strictly oligopause sensu Mansingh (1971), response in the adult stage differed among populations under 10L:14D at 15℃. The percentage of newly emerging females with immature ovaries was significantly lower in one of the Kagoshima populations, KGS1 (12%) than in the other four populations (51-66%). The mean preoviposition period was significantly shorter in the Kochi population, KCH (1.8d) than in the Kyoto population (7.8d), and oviposition was more incessant in the former than in the latter. KGS1 and KCH, which showed a weaker diapause response, are considered to be better candidates for the biological control of pest aphids in winter greenhouses because they are more likely to be active during the winter.
