城市外环境灭蝇袋与捕蝇笼灭蝇效率比较

The comparison of capture efficiency between fly-bags and fly-cages in the outside urban environment

目的 比较灭蝇袋和捕蝇笼在城市外环境灭蝇效率的差异,为蝇类防治工作提供参考。方法 以蝇密度表示捕蝇效率,计算Shannon-Weiner指数蝇种属的多样性,用t检验比较差异显著性。结果 共计捕蝇3 608只,其中灭蝇袋捕蝇3 036只,捕蝇笼捕蝇572只。灭蝇袋法密度为(0.346±0.202)只/(袋·h),捕蝇笼法密度为(0.059±0.039)只/(笼·h),二者有显著统计学差异(t=5.105,P<0.01)。灭蝇袋和捕蝇笼均捕获蝇类12属。灭蝇袋法Shannon-Weiner多样性指数为1.621,捕蝇笼法Shannon-Weiner多样性指数为1.859,二者有显著统计学差异(t=5.97,P<0.01)。结论 灭蝇袋的灭蝇效率显著高于捕蝇笼。

Objective To compare the capture efficiency between fly bags and fly cages in outdoor environment,and provide reference for fly control.Methods The efficiency of fly trapping was displayed by density,and Shannon-Weiner index was calculated to represent the diversity of fly species.The significance of differences was compared by t-test.Results A total of 3608 flies were captured,3036 by the fly-bag and 572 by the fly-cage.The fly densities were(0.346±0.202)flies/(bag·h)by fly bags and(0.059±0.039)flies/(cage·h)by fly cages,with statistically significant difference(t=5.105,P<0.01).12 genera of flies were captured.The Shannon-Weiner diversity indexes were 1.621 by fly bags and 1.859 by fly cages,with significant difference(t=5.97,P<0.01).Conclusion The trapping efficiency of fly bags was significantly higher than that of fly cages.
