摘要
[目的]测试6种瓢虫对胡萝卜微管蚜的捕食功能反应。[方法]在室内分别测试了八斑和瓢虫[Harmonia octomaculata(Fabricius)]、粗网巧瓢虫[Denopie chinensis(Weise)]、六斑月瓢虫[Menochilus sexmaculata(Fabriciys)]、红星盘瓢虫[Phrynocaria congener(Billberg)]、龟纹瓢虫[Propylea japonica(Thunberg)]、狭臀瓢虫[Coccinella transversalis(Fabricius)]6种瓢虫成虫对胡萝卜微管蚜(Semiaphisheraclei Takahashi)的捕食功能反应。[结果]胡萝卜微管蚜的密度与6种瓢虫各1头成虫对相应密度蚜虫的捕食率呈极显著负相关,6种瓢虫成虫对胡萝卜微管蚜的捕食功能反应符合Holling-Ⅱ型反应。八斑和瓢虫、粗网巧瓢虫、六斑月瓢虫、红星盘瓢虫、龟纹瓢虫、狭臀瓢虫各1头成虫对胡萝卜微管蚜的日最大潜在捕食量分别为159.52、193.53、129.57、140.76、120.20、147.34头,其中以粗网巧瓢虫成虫控制蚜虫的潜力最大。[结论]粗网巧瓢虫成虫可作为捕食蚜虫的瓢虫优势种加以保护利用。
[Objective] The aim was to test the predatory effect of six species ladybird on Semiaphis heraclei Takahashi.[Method] Predatory effects of six species of ladybirds like Harmonia octomaculata Fabricius,Denopie chinensis Weise,Menochilus sexmaculata Fabriciys,Phrynocaria congener Billberg,Propylea japonica Thunberg and Coccinella transversalis Fabricius on Semiaphis heraclei Takahashi were tested under indoor conditions.[Result] There was a negative correlation between the density of S.heraclei and predatory rate of each head of six species of ladybirds on corresponding density of aphids.Predatory effects of these six species ladybird on S.heraclei were coincident with Holling-II type response.The daily max potential predation number of each head of these six species of ladybirds on S.heraclei was 159.52,193.53,129.57,140.76,120.20 and 147.34 heads,respectively,among them Denopie chinensis Weise showed large potentiality in controlling aphid.[Conclusion] Denopie chinensis Weise adults could be taken as dominant species for controlling aphid,so they are worth protection and using.
