Abstract:

Objective To investigate the attractive effects of different concentrations of lactic acid, enanthic acid, methacrylate, trimethylindole, and dimethyl disulfide on Musca domestica. Methods Lactic acid, enanthic acid, methacrylate, trimethylindole, and dimethyl disulfide were separately diluted with corn flour to different concentrations, and these compounds were put in the bait trays of mosquito-fly traps. The traps were placed in a mosquito net to capture adult M. domestica. Results Compared with controls, 0.1 and 1.0 mg/kg lactic acid led to 50.0% and 53.0% increases in number of captured houseflies, 0.1 and 1.0 mg/kg enanthic acid led to 210.7% and 77.7% increases in number of captured houseflies, 1000.0 mg/kg methacrylate led to a 155.1% increase in number of captured houseflies, 1.0 and 10.0 mg/kg trimethylindole led to 81.6% and 139.8% increases in number of captured houseflies, and 10.0 and 100.0 mg/kg dimethyl disulfide led to 137.3% and 168.7% increases in number of captured houseflies. Conclusion Considering the attractive effect and compound odor, lactic acid and enanthic acid may be used as the components of bait for indoor housefly control, and methacrylate, trimethylindole, and dimethyl disulfide may be used as the components of bait for outdoor housefly control.

摘要：

目的 了解乳酸、正庚酸、丙烯酸甲酯、三甲基吲哚和二甲基二硫醚5种化合物在不同浓度下对家蝇的引诱效果。方法 将5种化合物用玉米粉稀释成不同浓度,然后将不同浓度的同种化合物分别放在蚊蝇诱捕盒的饵料盘中,在蚊帐内对家蝇成虫进行引诱实验。结果 0.1、1.0 mg/kg的乳酸,0.1、1.0 mg/kg的正庚酸,1000.0 mg/kg的丙烯酸甲酯,1.0、10.0 mg/kg的三甲基吲哚,10.0、100.0 mg/kg的二甲基二硫醚引诱的家蝇数量比对照分别多50.0%和53.0%、210.7%和77.7%、155.1%、81.6%和139.8%、137.3%和168.7%。结论 综合考虑引诱效果和化合物气味,乳酸和正庚酸可作为室内家蝇引诱剂的成分用于家蝇诱杀,丙烯酸甲酯、三甲基吲哚和二甲基二硫醚可作为室外家蝇引诱剂的成分用于家蝇防治。
