摘　　要：目的掌握重庆市室内蜚蠊的侵害情况,有效控制其密度,为今后大面积灭蜚蠊积累经验。方法统一时间、统一药物,采用滞留喷洒法和毒饵法集中杀灭,并用药激法和目测法考核灭蜚蠊效果。结果灭前蜚蠊平均侵害率达27.75%,6种不同类型场所蜚蠊的侵害程度差异有统计学意义(χ2=91.272,P<0.01);灭后蜚蠊的侵害率降至6.46%,杀灭率为76.72%。其中学校的灭蜚蠊效果最好,杀灭率为91.95%;其次是农贸市场,为86.19%";五小店"相对最差,杀灭率仅为60.79%。6种不同类型场所的灭蜚蠊效果差异也有统计学意义(χ2=55.235,P<0.01)。结论本次全市统一灭蜚蠊取得了明显效果,有效降低了蜚蠊密度。同时体会到不同类型场所的灭效高低,与其环境条件因素的影响以及灭蜚蠊工作力度和重视程度有很大关系。环境条件较好,灭蜚蠊相对较易;工作力度越大,重视程度越高,灭效就越显著。Objective To learn the infestation situation of indoor cockroach in Chongqing, and control effectively its density to accumulate experience for its large scale control. Methods The residual spraying and toxic baits were used to kill cockroach, and the control efficacy was evaluated by chemicals simulating method and visual method. Results The infestation rate reached 27.75% before treatment, and there was significant difference among the infestation situation of cockroach at six different places （χ^2=91.272, P〈0.01）.Afier treatment, it decreased to 6.46% and the killing rate was 76.72%. The control efficacy in the school was the best, and the killing rate reached 91.95%. The second was in the farm product trade market with the value of 86.19%. It was the worst in five small shops, and its killing rate to cockroach was only 60.79%. There was also significant difference among the control efficacy at six places （χ^2=55.235, P〈0.01 ）. Conclusion The control efficacy to cockroach was very distinct, which effectively reduced the density of cockroach. The results also showed many factors such as environment, work force and concern degree would affect the control effect. The environmental condition was better, the control of cockroaches was easier. The work force was bigger and the degree of concern was higher, the killing effect was more remarkable.
