摘　　要：【目的】开发利用中草药植物资源,建立红铃虫监测与防治新技术。【方法】以花椒(Zanthoxylum bungeanum)、黄柏(Cortex phellodendri)、云木香(Saussurea costus)、五倍子(Rhus chinensis)4种中药材提取物为对象,研究红铃虫(Pectinophora gossypiella)成虫对其电生理和嗅觉反应,并进一步探究复配剂的增效作用。【结果】当气味源的质量浓度为15 g·L^(-1)时,花椒和云木香提取物均可引起红铃虫成虫强烈的电生理反应;嗅觉试验结果表明,花椒提取物对于雌雄虫均有极显著的引诱作用,选择反应率分别为67.26%和76.72%;云木香提取物对于雄虫具有极显著的引诱作用,选择反应率为71.19%;2种提取物的诱捕效果与棉花植株相当。复配试验结果表明,花椒提取物与芳樟醇按体积比3︰7和6︰4复配,分别对雌虫和雄虫的诱捕表现出显著的增效作用。【结论】本研究通过一系列室内试验初步筛选出了2种对红铃虫有较高活性的具有潜在应用价值的引诱剂配方(花椒提取物与芳樟醇按体积比3︰7和6︰4复配),可为红铃虫的监测和绿色防控提供技术和数据支撑。[Objective]The purpose of this study is to utilize Chinese herbal medicine resources and to establish new monitoring and control technology of Pectinophora gossypiella.[Method]The electrophysiological and olfactory responses of P.gossypiella to the extracts of Zanthoxylum bungeanum,Cortex phellodendri,Saussurea costus,and Rhus chinensis were studied in this study,and the synergism of the extracts was further studied.[Result]The extracts of Z.bungeanum and S.costus could induce strong electrophysiological responses of P.gossypiella when the concentration of odor source was 15 g·L^(-1).The results of olfactory test showed that the extracts of Z.bungeanum had significant attraction to both female and male adults,and the selected response rates were 67.26%and 76.72%,respectively.The extract of S.costus had a very significant attraction to male adults,and the selected response rate was 71.19%.Further studies showed that the attractive effect of these two extracts was similar to that of cotton plants.Z.bungeanum extract mixed with linalool with the ratio of 3:7 and 6:4(by volume),showed significantly synergistic effect on male and female insects respectively.[Conclusion]Based on a series of indoor experiments,two potential attractant,the mix ratio of Z.bungeanum extract to linalool was 3:7 and 6:4,with high activity to P.gossypiella were screened,which can provide support for the detection and green control of P.gossypiella.
