摘　　要：【目的】明确桃潜叶蛾与梨小食心虫性信息素的互作效应。【方法】通过触角电位技术和田间诱捕试验,分别探究桃潜叶蛾与梨小食心虫雄虫对异种昆虫性信息素的触角电位反应以及不同剂量2种性信息素混合使用时对桃潜叶蛾与梨小食心虫田间诱捕效果的影响。【结果】桃潜叶蛾雄虫触角能够感知剂量为0.1μg的梨小食心虫性信息素,梨小食心虫雄虫能够明显感知100.0μg桃潜叶蛾性信息素且触角电位值随性信息素剂量增加而增大。50.0~500.0μg梨小食心虫与1.0 mg桃潜叶蛾性信息素混用时的诱蛾效果与1.0 mg桃潜叶蛾对照诱芯相比无显著差异,1.0~2.0 mg桃潜叶蛾与50.0μg梨小食心虫性信息素混用时的诱蛾效果与50.0μg梨小食心虫对照诱芯相比也无显著差异。【结论】桃潜叶蛾与梨小食心虫能相互感知对方性信息素,且2种性信息素混合使用时对二者田间诱捕效果无影响,今后可作为复合诱芯或迷向剂在果园内同时监测或防治桃潜叶蛾与梨小食心虫。【Objective】Lyonetia clerkella L.(Lepidoptera,Lyonetiidae)and Grapholitha molesta B.(Lepidoptera,Tortricidae)are important pests in orchards,which damage leaves,twigs and fruits of peach,pear,apple,plum,apricot and other fruit crops.Due to the damaging characteristics of the two pests,the control effect by chemical pesticide is limited.Insect sex pheromones have been widely used in integrated pest management including the sex pheromone of L.clerkella and G.molesta.Their occurrence periods of two insects overlap throughout the year.The purpose of this study was to explore the interaction effect between two sex pheromones by means of Electroantennogram(EAG)and field trapping tests.One of the objectives of this study was to test whether male moths of L.clerkella and G.molesta can perceive sex pheromones of each other;and another objective was to determine whether the two synthetic sex pheromones could be blended into a lure for monitoring and controlling the both insect pests simultaneously.The results can provide a basis for the development of a blending lure to save the cost of management and improve multi-species control efficiency.【Methods】This study was divided into two parts:EAG test and field trapping test.The sex pheromone of L.clerkella used was 14-methyl-1-octadecene and the sex pheromone of G.molesta was composed of(Z)-8-dodecenyl acetate(Z8-12:OAc),(E)-8-dodecenyl acetate(E8-12:OAc)and(Z)-8-dodecen-1-ol(Z8-12:OH)in a ratio of 95∶5∶5.In the EAG test,the different doses of sex pheromone of G.molesta(0.1,1.0,10.0,100.0 and 500.0μg)were used to stimulate the antenna of L.clerkella male moth,and then the 5 same pheromone doses of L.clerkella were to stimulate the antenna of G.molesta male moth conversely.The paraffin oil was used as control.Each EAG test was repeated for 8 times.In the field trapping test,the different doses of sex pheromone of G.molesta(50.0,100.0,200.0,300.0 and 500.0μg)were mixed respectively with1.0 mg pheromone of L.clerkella,and then 1.0 mg and 2.0 mg doses of sex pheromone
