目的对比研究当地政府开展统一灭蟑对蟑螂密度监测的影响,为灭效评估提供参考。方法使用2007-2012年全国病媒生物监测某国家级监测点室内蜚蠊密度数据,对灭(未灭)蟑年密度监测数值由Mann-Kendall方法做突变检验分析。结果统一灭蟑对蟑螂密度监测无影响(Z:-0.5~-0.8,P>0.1)。结论统一灭蟑对该市国家病媒监测的蟑螂密度没有产生差异有统计学意义的改变,灭效评估应采用其它方法。
Objective To comparatively study the influence of local government on cockroach density monitoring by unified cockroach killing and provide references for the evaluation of culling. Methods The national cockroach density data from a national monitoring site during 2007-2012 were used to monitor the annual density of cockroaches in China. Mann-Kendall method was used to detect the annual density of offspring. The results of a unified cockroach cockroach density monitoring had no effect (Z: -0.5 ~ -0.8, P> 0.1). Conclusion There is no statistically significant difference in the density of cockroaches monitored by the national vector in the city due to the unified cockroach killing. Other methods should be used to assess the effectiveness of the culling.
