摘要
【目的】研究四斑月瓢虫对紫薇长斑蚜控害能力。【方法】以紫薇上主要害虫紫薇长斑蚜及其天敌四斑月瓢虫为研究对象,在室内人工气候箱中研究四斑月瓢虫成虫对紫薇长斑蚜的捕食功能反应及种内干扰作用。【结果】四斑月瓢虫对紫薇长斑蚜的捕食功能反应符合Holling-Ⅱ型,其拟合方程为N a=0.7172 N t/(1+0.0025 N t),四斑月瓢虫对紫薇长斑蚜的理论日最大捕食量为286.86头。四斑月瓢虫的寻找效应随着猎物密度的增加而降低。四斑月瓢虫的种内干扰方程为E=0.4644P-1.3675。【结论】四斑月瓢虫对紫薇长斑蚜有较强的捕食作用和控害潜力。
【Objective】This project aims to assecse the biological control potential of Chilomenes quadriplagiata on Tinocallis.kahawaluokalani.【Methods】Chilomenes quadriplagiata is an important natural enemy of the crape myrtle aphid Tinocallis kahawaluokalani.The predation and intraspectic disturbance of the adults of C.quadriplagiata to the T.kahawaluokalani were studied in a controlled climatic chamber held at(22±1)℃,(65±10)%RH,and photoperiod of 14∶10(L∶D)h.【Results】The results showed that the functional response of C.quadriplagiata to T.kahawaluokalani fitted well with the Holling-Ⅱequation.The fitting equation was N a=0.717,2N t/(1+0.002,5 N t),and the maximum daily predation number was 286.86.The searching efficiency of C.quadriplagiata to T.kahawaluokalani was gradually decreased with the increase of prey density.The intraspecific interference equation was E=0.464,4P-1.367,5.【Conclusion】The results indicate that C.quadriplagiata is an effective predator and has a high potential in control T.kahawaluokalani.
