中文摘要： 黄脊竹蝗Ceracris kiangsu Tsai成虫对发酵人尿及汗液有明显的趋向行为。利用昆虫
触角EAG反应和林间诱蝗试验对氯化钠、碳酸氢氨及乙醇3种主要的人尿、汗液化合物的诱蝗
活性进行测定。结果表明：3种物质均能明显激发黄脊竹蝗雌、雄成虫的触角电位反应，激发活性的强弱
次序为乙醇>碳酸氢氨>氯化钠。3种化合物对雌蝗触角的刺激作用强于雄蝗。在林间，氯化
钠、碳酸氢氨及乙醇及其混合物对竹蝗的引诱效果不明显，化合物浓度及药剂种类是影响竹
蝗引诱量的因子之一。
英文摘要： Adults of Ceracris kiangsu Tsai were attracted by zymolytic human urine and sweet. The attractive activities of three chemicals of human urine, sodium chloride, ammonium bicarbonate and ethanol, towards C .kiangsu adults were investigated with EAG response and trapping test in bamboo forest.The results showed that all the three chemicals could elicit significant EAG values from the antennae of both female and male adults, and the maximum EAG value was evoked by ethanol, the minimum was elicited by sodium chloride. Higher EAG responses of female antennae were observed in response to the three chemicals than male antennae. In field test, attractive activities of the three chemicals and their blends to C. kiangsu adults were not significant, and the concentration of chemicals and the pesticides mixed were the factors that could affect the trapping quantity of C.. kiangsu adults.
