摘要
通过调查发现古路板油松林内有瓢虫７种，其中Ｎｅｏｍｙｓｉａｋａｓａｉｉｋｕｒｉｓａｋｉ为优势种；测定优势种和异色瓢虫Ｌｅｉｓａｘｙｒｉｄｉｓ（Ｐａｌｌａｓ）捕食松大蚜（ＣｉｎａｒａｐｉｎｉｔａｂｕｌｅａｆｏｒｍｉｓＺｈａｎｇｅｔＺｈａｎｇ的功能反应，比较两种瓢虫的捕食饱和能力、处理时间和瞬时攻击速率评价优势种Ｎ．Ｋａｓａｉｉｋｕｒｉｓａｋｉ是一种具有较高捕食效率的天敌，对松大蚜捕食饱和能力为５５６头，瞬时攻击速率为０．８９７４，处理时间只有０．００１８天，理论上讲它能够有效地控制松大蚜的危害。
By means of investigation it is turned out that there are seven kinds of Ladybirdsin the woods of Pinus tabaleaformis in Gu LouBang Forestry farm and Neomysia kasaiiKurisaki is a dominant species of the ladybird community.By making experiments of thefunction response of N. kasaii and Leis axyidis,We appraise the predatory efficiency of N. kasaii by comparing its maximus predatory capacity,handling time and rate of a wink attackwith L. axyridis′.The dominant species is a kind of the matural enemy of Cinara pinita-baLeaformis with high predatory efficiency. Its maximus predatory capacity is 556 , handlingtime is 0.0018 and the rate of a wink attack is 0.8974.
