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.
