摘要
在实验室条件下 ,研究了多异瓢虫在不同空间大小及异质性条件下对麦长管蚜的功能反应和种内干扰。结果表明 :在不同空间大小及异质性条件下 ,多异瓢虫成虫和各龄幼虫对麦长管蚜的功能反应均符合 Holling 反应 ,并存在着相互干扰 ;随幼虫龄期的增加 ,攻击率、搜索系数、捕食效率及干扰系数增大 ,成虫攻击率、搜索系数、捕食效率及干扰系数低于 3、4龄幼虫 ;随空间及异质性的增大 ,成虫和各龄幼虫攻击率、搜索系数、捕食效率及干扰系数减小。
In the lab,the functional responses and intraspecific interferences of Adonia variegata (Goeze)on the wheat phid,Macrosiphum avenae(F.)were studied.The results showed that funcitonal responses and intraspecific of the adult coccinellid and larvae on the wheat aphid could be described by Holling`s Ⅱequation and Hassell`s equation,respectively,Under the condition of different space size and heterogeneity.The instantaneous attack rates,predation efficiency,questing coefficients,and interferents Coefficients of the larva coccinellid increased with the adding of the instars,and these coefficients of the abult were smaller than those of third or forth instars larvae while they decreased with the increase of space size and heterogeneity.
