摘要: 【目的】研究喂饲棉蚜对方斑瓢虫生长发育及捕食功能反应的影响。【方法】以非转基因棉花品种中棉所49号为材料,在室内研究方斑瓢虫Propylaea quatuordecimpunctata取食棉蚜Aphis gossypii的生长发育及捕食功能反应。【结果】方斑瓢虫1龄平均龄期为1.73 d,2龄平均龄期为2.04 d,3龄平均龄期为1.64 d,4龄平均龄期为1.92 d,蛹期为3.09 d。方斑瓢虫各龄幼虫和成虫的捕食功能反应均属于Holling Ⅱ 型圆盘方程,在棉蚜密度相同下,4龄幼虫和成虫取食量远高于低龄幼虫;方斑瓢虫捕食量均随棉蚜密度的增加而增加,当棉蚜密度增加到一定水平,捕食量趋于稳定。方斑瓢虫各龄幼虫、成虫对棉蚜的寻找效应随猎物密度的增加而减少。【结论】方斑瓢虫取食棉蚜的发育历期室温下为7.3 d,蛹期为3.1 d。方斑瓢虫对棉蚜具有良好的控害潜能。

Abstract: 【Objective】 To clarify the effects of feeding Aphis gossypii on the growth and development of predatory functional response of P. quatuordecimpunctata.【Method】 Based on non-transgenic cotton CCRI 49, the functional response and development of different stages of P. quatuordecimpunctata to Aphis gossypii was researched in laboratory.【Result】 The results showed that the average age of the 1st instar larvae of P. quatuordecimpunctata was 1.73 days, the average age of 2nd instar larvae was 2.04 d,the average age of 3rd instar larvae was 1.64 d, and the 4th instar larvae was 3.09 d. Functional response of the adults and larvae of P. quatuordecimpunctata to the density of Aphis gossypii fitted well with Holling Ⅱ model, and under the same density of cotton aphids, the feeding capacity of 4-instar larvae and adults was much higher than that of younger ones. The larvae and adult of P. quatuordecimpunctata had the larger predation number and the lower hunting efficiency with the increase of prey density, but the predation number went to a steady value when the quarry density increased to a certain degree.【Conclusion】 The development of duratioin of P. quatuordecimpunctata which preyed on the Aphis gossypii in the laboratory.was 7.3d, 3.09d/pupal, and P. quatuordecimpunctata is a potential natural enemy for A. gossypii.

Key words: Aphis gossypii; Propylaea quatuordecimpunctata; growth and development; functional response; searching efficiency
