Abstract: To understand the preference of Lysiphlebia japonica Ashmead for Aphis gossypii Glover reared on different host plants, we investigated population dynamics, parasitism and weight of the insects. Population size of insects (including A. gossypii, L. japonica and mummified aphids) on zucchini was the largest and significantly higher than those on cotton and cucumber. Adult aphid weight was significantly higher on zucchini than that on cotton and cucumber in both laboratory and field cage tests. L. japonica had a higher parasitism rate for the aphids on zucchini. L. japonica (obtained from zucchini) showed parasitism rates of 81.3%, 58.3% and 44.0% on zucchini, cotton and cucumber, respectively. This study preliminarily showed that L. japonica prefer for zucchini, which could help biological control using L. japonica.

Key words: Aphis gossypii, Lysiphlebia japonica, mummified aphids, plant volatiles, parasitism rate
