目的 :观察自动捕蝇器的捕蝇效果。方法 :将捕蝇器放置于模拟室中央离地面 1.2m高处 ,在滚筒上加涂引诱剂 ,连续开启 4h记录捕获蝇数。结果 :连续开启 4h的平均捕获率为87.83% ,分时段捕捉的累计 4h家蝇平均捕获率为 51.33% ,差异有非常显著意义。结论 :根据家蝇的聚集现象 ,可提高捕蝇器的捕蝇率。 Objective: To observe the automatic flytrap catching fly effect. Methods: The flycatcher was placed in the center of the simulation room 1.2m above the ground height, and a attractant was applied to the drum to record the number of captured flies continuously for 4h. Results: The average capture rate of 4h continuous opening was 87.83%, and the average capture rate of 4h housefly captured in different time period was 51.33%. The difference was significant. Conclusion: According to the accumulation of housefly, the catching fly rate of the fly can be increased.
