摘要: 目的 研究十一星瓢虫对棉蚜和棉长管蚜捕食选择性,为利用十一星瓢虫调控棉蚜以及研究由天敌介导的棉蚜与棉长管蚜种间竞争关系提供依据。方法 在室内控制条件下,测定十一星瓢虫对棉蚜和棉长管蚜不同密度下捕食量、取食棉蚜和棉长管蚜对其生长发育的影响,以及对两种蚜虫的选择性。结果 十一星瓢虫对棉蚜和棉长管蚜具有良好的捕食作用,成虫日捕食量分别为107.67和98.67头;取食棉蚜和棉长管蚜均能完成正常的生长发育,体重和成虫性比等指标均无明显差异。两种蚜虫等密度组合,十一星瓢虫对棉蚜表现出一定选择性,成虫选择性强于幼虫,而且随密度增加选择性增强;两种蚜虫配置不同比例可影响瓢虫的捕食选择性。结论 十一星瓢虫取食两种蚜虫均能完成正常的生长发育,两种蚜虫等密度组合条件下,瓢虫对棉蚜表现出一定的选择性。

Abstract: Objective In order to study the predation and selection of Coccinella undecimpunctata on Aphis gossypii and Acyrthosiphon gossypii in the hope of providing scientific basis for controlling A. gossypii and understanding the competition between A. gossypii and Ac. gossypii mediated by natural enemy. Method Under the condition of indoor control, the preying amount, growth and development effects of C. undecimpunctata feeding on A. gossypii and Ac. gossypii at different densities and the selection effect on the two aphids were determined.Result C. undecimpunctata had good predation to A. gossypi and Ac. gossypii. The maximum daily predation of adults of C. undecimpunctata were 107.67 and 98.67, respectively. Feeding on A. gossypi and Ac. gossypii could complete the normal development. There were no significant difference in growth, body weights and adult sex ratio. Under the same density combination of two aphids, C. undecimpunctata showed positive selection effect on the A. gossypii, and the adult had a stronger selective effect than the larvae, and the selection effect increased with the increase of density. When aphids were allocated in different proportions, the proportion of Ac. gossypii increased with the increase of the proportion of aphids, and the selection effect of C. undecimpunctata on Ac. gossypii were increased. Different density combinations of two aphids could affect the predation selection of C. undecimpunctata. Conclusion C. undecimpunctata feeding on two aphids can achieve normal development. Under the condition of equal density combination of the two kinds of aphids, C. undecimpunctata showed a positive selection effect on A. gossypii, and adults have a stronger selection effect than 3rd instar larvae.

Key words: Coccinella undecimpunctata; Aphis gossypii; Acyrthosiphon gossypii; prey selection
