目的对2种诱饵在笼诱法蝇密度监测中的效力差异做初步比较。方法笼诱法监测蝇密度,诱饵使用腐鱼内脏与糖醋水混合物。使用χ2检验统计蝇种构成比差异,圆形分布法计算诱饵间季节消长。结果 2种诱饵捕获蝇类种类无差异,糖醋饵诱获物中以丝光绿蝇占优,腐鱼饵诱获物仍以丝光绿蝇占优,但两者捕获蝇当中铜绿蝇与大头金蝇占比存在差异。结论 2种诱饵对铜绿蝇(χ2=5.04,ν=1,P=0.02)和大头金蝇具有引诱力差异(χ2=34.29,ν=1,P=0.000),诱饵间蝇类季节消长差异无统计学意义(t=0.797,P>0.3),国家蝇密度监测方法可用于成都市。
Objective To compare the efficacy of two kinds of baits in monitoring density of trapped flies. Methods Cage induction method was used to monitor the density of flies and bait was used to mix the rotten viscera with the sweet and sour water. The χ2 test was used to calculate the compositional ratio of flies, and the circular distribution method was used to calculate the seasonal fluctuation of lures. Results There was no difference in the species of flies caught by the two kinds of bait, while the predators in the sweet and sour bait were predominant in the green flies, while the bait in the bait was dominated by the green flies, The proportion of differences. Conclusions The two bait strains have the same ability of inducing flies (χ2 = 34.29, ν = 1, P = 0.000), but no difference in seasonal fluctuation between bait flies (χ2 = 5.04, ν = Statistical significance (t = 0.797, P> 0.3), national flies density monitoring method can be used in Chengdu.
