摘要: 【目的】研究温度变化对多异瓢虫[Adonia variegata ( Goeze)]成虫捕食棉蚜能力的影响。【方法】在17、23、29和35℃四个处理温度下,室内测定多异瓢虫成虫在不同棉蚜密度条件下的捕食量。【结果】不同温度下多异瓢虫成虫对棉蚜的捕食功能反应属于Holling-Ⅱ型。随着温度的升高,多异瓢虫成虫对棉蚜的捕食能力逐渐增加。在相同温度条件下多异瓢虫成虫对棉蚜的寻找效应随密度的增加而减小。在35℃条件下,多异瓢虫成虫的a/Th最大,捕食能力为17℃的2倍。【结论】温度对多异瓢虫的捕食量影响显著,在一定温度范围内,随温度升高,多异瓢虫成虫的捕食量明显增加。

Abstract: 【Objective】 To study the effects of temperature change on the predation functional responses of adult of Adonis variegata (Goeze).【Method】At four processing temperatures:17℃,23℃,29℃ and 35℃, the predation ability of adult of Adonia variegata (Goeze) to Aphis gossypii Glover at different density conditions was determined in doors.【Result】The results showed that predation responses of adult of Aphis gossypii (Goeze) to Aphis gossypii Glover belonged to Holling-II at different temperatures. With the increase of temperature, the predatory ability of Adonia variegata (Goeze) to Aphis gossypii Glover gradually increased. Under the same temperature conditions, the searching effect of adult of Adonis variegata (Goeze) to the Aphis gossypii Glover decreased with the increase of density. At 35℃, the ratio of a/Th of the Adonia variegata (Goeze) was the largest and the predation ability was twice as high as that at 17℃. 【Conclusion】The temperature has a significant effect on the predation. Within a certain temperature range, the increase of temperature is favorable to the predation of Aphis gossypii Glover on the Adonis variegata (Goeze).
