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。
Under laboratory conditions, the functional responses and intraspecific interferences of S.millers to S. avenae under different spatial and heterogeneous conditions were studied. The results showed that under different spatial and heterogeneous conditions, the responses of adults and juvenile larvae to Hollosporium australis were all in accordance with the Holling reaction, and there existed mutual interference. With the increase of larval instars, the attack The rate of infestation, search efficiency, predation efficiency and disturbance coefficient increased, the attack rate of adults, search coefficient, predation efficiency and disturbance coefficient were lower than those of 3rd and 4th instar larvae. With the increase of space and heterogeneity, , Search coefficient, predation efficiency and interference coefficient decrease.
