摘　　要：目的现场探索3种蜚蠊密度测定方法之间在同一个单位内的有效性和可比性,以便积累数据,为统一蜚蠊密度监测、蜚蠊控制效果检查方法提供科学依据。方法选择3种蜚蠊侵害程度不同的单位,分别运用3种常用的蜚蠊密度监测和密度测定方法,在同一现场按照先目测、后粘捕、最后药激的程序同步进行比较试验。数据统计采用χ2检验、两样本均数比较和one way ANOVA处理。结果(1)31家试验场所用3种方法同时检测,除3家未发现蜚蠊外,其他28家均不同程度地检测到蜚蠊侵害。(2)目测、粘捕和药激法检测的阳性率分别为48.82%、46.08%和48.44%,3种方法阳性检出率之间差异无统计学意义(χ2=0.556,P≥0.05),密度指数分别为9.65只/间、7.04只/张和13.57只/间。(3)侵害程度无论高、中或低,3种方法检测获得的蜚蠊阳性率和密度指数值之间的差异均无统计学意义。结论目前使用的3种监测方法均可用于密度监测和调查以及效果评价,但无论采用哪一种监测或调查方法,样本量的大小、监测人员的责任心和规范的实施与否将直接影响到阳性率和密度指数的高低,建议进一步研究建立粘蟑纸法的指标值。Objective To evaluate the effectiveness and comparability of three methods of cockroach density monitoring in the same unit, providing scientific basis for the standardization of cockroach density monitoring and the assessment of control efficacy. Methods Three commonly used density monitoring and measurement approaches were tested in three units with different infestation rates. For each place, visual observation, glue traps and sprays were concurrently conducted in order. Data statistics was tested using Chi-square, two-sample mean-comparison test and one-way ANOVA. Results （1） Except for three units where no cockroaches were captured, cockroaches were detected in 28 out of 31 experimental units by the three monitoring methods. （2） The detection rates of visual observation, glue traps and sprays were 48.82%, 46.08% and 48.44%, respectively, without statistically significant difference （χ^2=0.556, P≥0.05）. The density indexes were 9.65/room, 7.04/trap and 13.57/room, respectively. （3） Regardless of high, intermediate or low infestation rates, no statistical difference was shown in the positive rates and density indexes derived from three approaches. Conclusion The three methods were all useful in density monitoring, investigation and efficacy assessment. However, the sample size, the responsibility of monitors and the adherence to standard procedures determine the accuracy and reliability of positive rates and density indexes whichever approach is taken. Establishment of indexes for glue traps is desired.
