摘要: 在室内条件下研究了六斑月瓢虫Menochilus sexmaculata雌、雄成虫对烟粉虱Bemisia tabaci、豆蚜Aphis craccivora和玉米蚜Rhopalosiphum maidis的捕食作用.结果表明,六斑月瓢虫成虫对3种猎物的捕食功能反应均符合HollingⅡ功能反应模型,经χ2检验,其理论值与观察值差异不显著.捕食功能反应参数反映六斑月瓢虫雌、雄成虫对烟粉虱、玉米蚜和豆蚜的捕食量差异显著,其最大日捕食量分别为86.21、217.39、303.03头和60.98、151.52、153.85头.六斑月瓢虫雌、雄成虫的搜寻效应均随猎物的密度增加而降低,且以取食豆蚜和玉米蚜的搜寻效应大于烟粉虱.六斑月瓢虫成虫对3种猎物的控制能力大小依次为豆蚜> 玉米蚜> 烟粉虱,且雌成虫大于雄成虫.

Abstract: Predatory function responses of Menochilus sexmaculata female and male adults to Bemisia tabaci, Aphis craccivora and Rhopalosiphum maidis were measured in laboratory. Predatory capacities of M. sexmaculata increased with the increase in prey density. The functional responses of M. sexmaculata adults to the three prey density fitted well with HollingⅡmodel. Chi-square test showed no significant differences between theoretic values and the observed values. There were significant differences in the predatory capacities to the three prey species. The maximum daily predatory capacities of female and male M. sexmaculata adults to B. tabaci, A. craccivora and R. maidis were 86.21, 217.39, 303.03 and 60.98, 151.52, 153.85, respectively. Searching rate of M. sexmaculata decreased with the increase in prey density and was higher on A. craccivora and R. maidis than on B. tabaci. M. sexmaculata adults afforded control efficacy against the three prey species more in A. craccivora, less in R. maidis and still less in B. tabaci, and female adults were more officious than males.
