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 master the indoor cockroach infringement in Chongqing and to control its density effectively so as to accumulate experience for large area cockroach removal in future. Methods Unified time, unified drugs, using detention spray method and bait method to kill, and the use of stimulus and visual evaluation cockroach effect. Results The average invasion rate of cockroaches was 27.75%, and there was significant difference in the degree of infestation of cockroaches in 6 different types of locusts (χ2 = 91.272, P <0.01). The infestation rate of cockroaches dropped 6.46% The off rate is 76.72%. Among them, the school had the best effect of killing cockroaches, killing rate was 91.95%; followed by farmers market, 86.19%; “Wudian” relatively the worst killing rate of only 60.79%. There were also significant differences in efficacy of cockroaches in 6 different types of venues (χ2 = 55.235, P <0.01). Conclusion The city of uniform cockroach achieved significant results, effectively reducing the cockroach density. At the same time realize the different types of places off the high and low, with its environmental conditions and the impact of cockroaches work intensity and emphasis on a great relationship. Better environmental conditions, killing cockroaches relatively easy; the greater the intensity of work, the higher the degree of emphasis, the more obvious the effect of killing.
