多异瓢虫对番茄潜叶蛾的捕食功能反应
Predatory Function of Hippodamia variegata(Goeze)to Tuta absoluta
摘要
Abstract
The control potential of Xinjiang's dominant predatory natural enemy,the adult Hippodamia variegata(Goeze),on Tuta absoluta was assessed by investigating the predatory functional responses to the 1st,2nd,and 3rd instar larvae of T.absoluta.The results showed that the daily predation amount of H.variegata adults on the 1st,2nd and 3rd instar larvae of T.absoluta were 66.33,60.00 and 40.33,respectively,showing a decreasing trend with the increase of larval instar.The predation functional response of H.variegata adults to the 1st,2nd and 3rd instar larvae of T.absoluta conformed to the Holling II disc equation,with theoretical maximum predation amounts of 454.55,161.29 and 81.97,respectively.The search effect of H.variegata adults on T.absoluta decreased with the increase of density and instar of T.absoluta larvae.The maximum search effects of H.variegata on the 1st,2nd and 3rd instar larvae of T.absoluta were 0.7376,0.7107 and 0.5303,respectively.The results show that H.variegata has good predation ability on the 1st,2nd and 3rd instar larvae of T.absoluta,and can keep the larvae of T.absoluta in check to a certain extent.Therefore,H.variegata can be further developed and utilized as a biological control agent for T.absoluta.关键词
