研究了人工选择降低飞行能力对异色瓢虫成活率和繁殖力的影响。在实验室条件下开始人工选择后的第36代，未飞菌株的孵化率、羽化率和繁殖力均显著低于对照。在有栽培茄子的温室里，释放了不能飞的品系，4龄幼虫，即释放的成虫的后代，比对照和商品品系延迟了7天的发生。这些结果表明，对飞行能力降低的人工选择降低了异色瓢虫的存活和繁殖特性。
The effects of artificial selection for reduced flight ability on the survival rate and fecundity of the ladybird beetle Harmonia axyridis were assessed. The hatching rate, emergence rate and fecundity of the flightless strain were significantly lower than the control in the 36th generation after artificial selection was started under laboratory conditions. In greenhouses containing cultivated eggplant in which the flightless strain was released, the incidence of fourth instar larvae, i.e., offspring of released adults, was delayed for 7 days compared with the control and commercial strain. These results suggest that artificial selection for reduced flight ability reduces the survival and reproductive characteristics of H. axyridis.
