摘    要:异色瓢虫Harmonia axyridis(Pallas)的法国种群具有飞行能力较低的特点,在生物防治方面可能更具利用价值。为了使其更好的在田间应用,本文进行了异色瓢虫的法国种群各龄幼虫及雌、雄成虫对豆蚜的捕食功能比较研究。结果表明:各龄幼虫及雌、雄成虫对豆蚜捕食功能反应符合Holling II模型,检验各圆盘方程理论值和实测值拟合较好。同一虫态在不同空间水平对蚜虫的捕食能力有显著差异,在广口瓶处理中(较大空间),1~4龄幼虫及雌、雄成虫的最大理论捕食量分别为4.51、83.33、111.12、166.67、190及200头;不同虫期及成虫的瞬间攻击率a为3龄>4龄>雄虫>雌虫>2龄>1龄,且1龄的处理时间Th最长(0.2225);在培养皿处理中(较小空间),1~4龄幼虫及雌、雄成虫的最大理论捕食量分别为6.17、19.23、45.45、100、142.86、111.11头,不同虫期的瞬间攻击率a为2龄>3龄>雄虫>4龄>1龄>雌虫,且4龄的处理时间Th最长(0.1624)。

关 键 词:异色瓢虫  法国种群  功能反应  空间水平  捕食效应

Abstract:The present laboratory study was a comparison among predation functional responses of different development stages(immature stages and adult) of the French non-flying form Harmonia axyridis to Aphis carvines.The results showed that the predation functional responses of each development stages all fitted as Holling II model.After chi-square test,the results showed there were not significant differences between theoretic values and the observational values.The differences of predatory capacity of same development stage in different space levels were significant.In bigger space treatment(glass jar),the maximum theoretic predatory amount of 1st~4th instar larvae,female and male adults were: 4.51,83.33,111.12,166.67,190 and 200,"a" were: 3th instar>4th instar>male adult>female adult>2th instar>1th instar,Th:the longest of treating duration "Th" was showed in 1st instar larvae(0.2225).Similarly in smaller space treatment(Petri dish),the maximum theoretic predatory amount of 1st~4th instar larvae,female and female adults were: 6.17,19.23,45.45,100,142.86,111.11.The parameters "a" were: 2th instar>3th instar>male adult>4th instar>1th instar>female adult and the longest of treating duration "Th" was showed in 4th instar larvae(0.1624).
Keywords:Harmonia axyridis  French wingless  functional response  different space levels  predatory amount
