摘要: 【目的】研究棉花和苘麻挥发物对棉大卷叶螟雌成虫的引诱作用,为开展棉大卷叶螟的绿色防控提供依据。【方法】以棉花品种泗棉3号和苘麻2种寄主为材料,使用Y型嗅觉仪测定棉大卷叶螟雌性成虫在这2种寄主植物上的选择偏好性。借助气-质联用(GC-MS)对收集到的2种寄主挥发物进行组分分析与鉴定,再通过EAG进行行为反应测试,检验卷叶螟成虫对这些特异性挥发物的电生理反应。【结果】棉大卷叶螟雌性成虫选择苘麻上的虫量是棉花上的2.3倍,在苘麻上的产卵量也是棉花上的1.7倍。棉花与苘麻2种寄主上有5种不同的挥发性特异物,棉大卷叶螟成虫对其中的2-乙基苯乙酮和3-乙基庚烷有明显的刺激反应。【结论】棉大卷叶螟成虫在选择产卵寄主时偏好苘麻,棉大卷叶螟雌性成虫对苘麻有明显的趋性,苘麻可作为棉大卷叶螟的引诱寄主。2-乙基苯乙酮和3-乙基庚烷2种挥发物对卷叶螟成虫有显著的刺激作用。

Abstract: 【Objective】 With the widespread cultivation of transgenic cotton, Sylepta derogata Fabricius, a leaf borer, has become an important leaf-feeding pest in cotton regions of Yangtze River basin. The attraction effect of cotton and abutilon to S. derogate was studied in order to provide scientific reference for pest green control.【Methods】 Host preference of S. derogate adult females between cotton varieties Simian 3 and abutilon was investigated by using Y-olfactometer. UThe components of the collected two host volatiles were analyzed and identified by gas-mass coupling GC-MS, and then the behavioral response test was performed by EAG to test the electrophysiological response of leaf borer adults to these specific volatiles.【Result】 The results showed that the number of female adult borers on abutilon is more than twice that on cotton, and the number of eggs on abutilon was 1.7 times that on cotton. There were 5 different specific volatiles in the two hosts. The female adults showed strong responses to p-Ethylacetophenone and 3-ethylheptane.【Conclusion】 S. derogate adult females more likely choose abutilon to lay eggs which indicates abutilon can be used as the trap host to control this pest; p-Ethylacetophenone and 3-ethylheptane exhibit significant attractive function which could be developed in future for the green control of this pest.
