摘　　要：研究桑螟性信息素引诱剂(简称性诱剂)的应用技术和效果,为桑螟性诱剂在桑园的推广应用提供参考。在桑螟发生期设置桑螟性诱剂诱捕器,监测分析桑螟在江西省桑园全年发生动态的同时,对影响桑螟性诱剂田间应用效果的多个因素进行分析。结果表明,诱捕器的安装密度、高度、位置、诱芯用量和诱芯更换时间均会对桑螟诱蛾量及防治效果产生影响,各个影响因子与桑螟诱蛾量之间的相关系数由大到小依次为诱捕器位置、诱捕器高度、诱捕器密度、诱芯用量、诱芯更换时间。综合考虑桑螟诱集数量、防治效果及经济成本,得出诱捕器安装密度15套/km2、诱捕器安装高度125 cm、诱捕器安放在桑园四周边缘、单套诱捕器诱芯数量1根时的防治效果最佳,并且在桑螟成虫发生高峰期更换桑螟性诱剂诱芯可提高对桑螟成虫的诱集数量和监控效果。利用桑螟性诱剂监测江西桑园桑螟的全年发生动态变化,可为桑螟防治适期预测提供参考。Application and effect of sex pheromone attractant(sex attractant in short)for mulberry borer were studied to provide a reference for the popularization and application of sex attractant in the mulberry field.In the occurrence period of mulberry borers,a trap was set to monitor and analyze the annual dynamic occurrence of mulberry borers in the Jiangxi mulberry field.Meanwhile,several factors influencing the field application effect of sex attractant were analyzed.The results showed that the density,height and position of installation,the amount of trap cores,and the replacement interval of trap core had effects on the quantity of trapped moths and the control effect.The correlation coefficient between each factor and the quantity of trapped moths was lined in a descending order as installation position,installation height,installation density,amount of trap cores,replacement interval of trap core.Taking quantity of trapped moths,control effect and economic cost into account,it was concluded that control effect was the best when installation density was 15 sets/km2,installation height was 125 cm,and the trap with one trap core by single trap was placed on the edge of mulberry field.Besides,replacement of trap core could improve the quantity of trapped moths and the monitoring effect during the occurrence period of adult mulberry borer.Therefore,application of sex attractant to monitor the annual dynamic changes of mulberry borer in the Jiangxi mulberry field could provide a reference for the prediction of suitable period to control mulberry borer.
