摘  要:
异色瓢虫是徂徕山林场常见天敌之一,在实验室条件下,测定了异色瓢虫对徂徕山林场2种重要蚜虫板栗大蚜和松蚜的选择效应。结果表明,当2种蚜虫种群数量同步增加,则取决于瓢虫原来的生境和饲喂条件,当板栗大蚜或松蚜种群上升时,则喜好取食种群数量大的蚜虫。

摘  要:
Harmonia axyridis(Pallas) is one of the important predators in the field. Its selective coefficient varies with the amount change of these two pest populations,Lachnus tropicalis and Cinara pinea in Forest Farm of Culai Mountain were measured under laboratory conditions. The results showed that when the two pest population numbers synchronous increased,the ladybirds which were collected the previous habits and raised the same aphids would like to predate it. But when L. tropicalis or C. pinea increased,H. axyridis would obviously like to predate it.
