摘　　要：目的 探讨冈田绕眼果蝇(Phortica okadai)对寄主挥发物的偏好性。方法 选择发酵梨挥发物的主要组分以及与人体有关的昆虫信息化合物作为引诱剂,利用Y型管对挥发物溶媒进行选择,利用自制四臂管对冈田绕眼果蝇的行为反应进行测定。结果 行为反应测定发现,共有9种挥发物组分对冈田绕眼果蝇具有引诱效果,其中2,3-丁二酮、苯乙醇、丙酸乙酯、辛酸乙酯、乙酸乙酯、月桂酸乙酯和正癸酸对雌、雄成蝇均具有引诱效应,而乙酸异戊酯只对雌成虫具有引诱作用,2,4-癸二酸-1-醇只对雄成虫具有引诱作用。另外发现了1种趋避剂芳樟醇。其他成分未发现引诱效应。结论 2,3-丁二酮、苯乙醇、丙酸乙酯、辛酸乙酯、乙酸乙酯、月桂酸乙酯和正癸酸能对冈田绕眼果蝇的嗅觉行为进行调控,可为开发针对冈田绕眼果蝇的引诱剂提供理论基础。Objective To investigate the preference of Phortica okadai for host volatiles.Methods The main components of volatile compounds of pear fermentation and insect information compounds related to human body were selected as attractants,and the Y tube was used to select the solvent of volatile compounds,and a self-made four-arm tube was used to measure the behavioral response of Phortica okadai.Results Behavioral response assays showed that nine volatiles had attractive effects on Phortica okadai.Among them,2,3-butanedione,phenethyl alcohol,ethyl propionate,ethyl octanoate,ethyl acetate,ethyl laurate and n-decanoic acid had attractive effects on both female and male adult flies,while isoamyl acetate only had attractive effects on female adult flies,and 2,4-sebace-1-ol only attractedthemale adults.An additional repellent,linalool,was found.No seductive effect was found for the other components.Conclusion 2,3-butanedione,phenethyl alcohol,ethyl propionate,ethyl octanoate,ethyl acetate,ethyl laurate and n-decanoic acid can regulate the olfactory behavior of Phortica okadai,which provides a theoretical basis for the development of attractant for Phortica okadai.
