摘要: 【目的】研究十一星瓢虫和龟纹瓢虫对[反]-β-法尼烯[(E)-β-farnesene](以下简称EβF)后的行为反应,为调控利用天敌治理棉蚜提供理论依据。【方法】于室内条件下,利用嗅觉仪测定不同浓度EβF对十一星瓢虫和龟纹瓢虫成虫和3龄幼虫的嗅觉行为选择,以及在棉花植株上释放不同浓度EβF对十一星瓢虫和龟纹瓢虫成虫和3龄幼虫对棉蚜取食选择的影响。【结果】EβF剂量为20和40 μL/mL时,可引起十一星瓢虫与龟纹瓢虫成虫和3龄幼虫明显的嗅觉选择行为反应;EβF处理剂量为10、20、40 μL/mL时,十一星瓢虫与龟纹瓢虫的成虫和3龄幼虫的取食选择率均明显高于对照。【结论】适宜的EβF剂量可引起2种瓢虫成虫和3龄幼虫明显的选择行为,EβF对自然天敌具有良好的生态调控作用。

Abstract: 【Objective】 Olfactory behavior response and feeding preference of Coccinella undecimpunctata and Propylaea japonica after releasing [E]-β-farnesene (reffered as EβF in the following part) were studied for providing scientific basis of controlling the population growth of cotton aphids through reasonable combination of natural enemies.【Method】In the laboratory, the olfactory behavior response of Coccinella undecimpunctata and Propylaea japonica on different doses of EβF were determined by olfactometer, and the feeding selective rates of adult ladybirds and 3rd instar larvae feeding on Aphis gossypii by releasing different doses EβF on cotton plants were calculated respectively in this study.【Result】Adult ladybirds and 3rd instar larvae of Coccinella undecimpunctata and Propylaea japonica showed an evident positive response to the dosage treatments 20 or 40 μL/mL EβF; The feeding selection responses of adults and 3rd instar larvae of Coccinella undecimpunctata and Propylaea japonica in the release concentrations of 10, 20 and 40 μL/mL EβF were significant higher than those in control group.【Conclusion】The behavioral responses of adults and 3rd instar larvae of the two ladybugs were significantly improved with the suitable dosages of EβF, and EβF played an obviously ecological role in regulation natural enemies of aphids.
