摘　　要：为明确新疆优势捕食性天敌多异瓢虫成虫对番茄潜叶蛾的控害潜能,本文研究了其对番茄潜叶蛾1龄、2龄和3龄幼虫的捕食功能反应。研究结果表明,多异瓢虫成虫对番茄潜叶蛾1龄、2龄和3龄幼虫的日捕食量分别是66.33头、60.00头和40.33头,表现出随着幼虫龄期的增大多异瓢虫成虫的捕食数量下降的趋势。多异瓢虫成虫对番茄潜叶蛾1、2、3龄幼虫的捕食功能反应均符合Holling II圆盘方程,其理论最大捕食量分别为454.55头、161.29头、81.97头,多异瓢虫成虫对番茄潜叶蛾的搜寻效应随着番茄潜叶蛾幼虫密度、龄期的增大而降低,多异瓢虫对番茄潜叶蛾1、2、3龄幼虫的最大搜寻效应分别是0.7376、0.7107、0.5303。表明多异瓢虫对番茄潜叶蛾1龄、2龄和3龄幼虫具有较好的捕食能力,可以在一定程度上控制番茄潜叶蛾幼虫,因此可以将多异瓢虫作为番茄潜叶蛾的生物防治材料进一步开发利用。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.
