摘要
目的摸清德国小蠊夜间活动规律,为有的放矢、采取科学的综合防制措施提供依据。方法选择4家饭店,采用定面积目测法观察,并对不同防制方法进行效果对比试验。结果(1)德国小蠊夜间栖息活动习性具有出穴活动高峰、空间分布呈“靶标”状态等特征。(2)A、B、C饭店经综合防制后的第30天,德国小蠊密度下降率达100%;D饭店仅单一投放灭蠊药,密度下降率为77.78%,两组间差异具有统计学意义(F=19.25,P<0.001)。结论灭前摸清德国小蠊生境、习性,采用堵洞抹缝、定位施药等综合防制措施效果显著。
Objective To find out the characteristic of the Blattella germanica activities at night, offer the basis for the scientific and integrated measures of prevention and control. Methods To choose 4 restaurants, and to carry on an effect contrast trial of different preventing and controlling measures, by eye observation in certain area. Results （1） The Blattella germanica activity behaviors at night has a character of activity peak and a drone spatial distributing. （2） After 30 days of integrated measures in restaurants A, B, C, the density of the Blattella germanica decreases by 100 %. In restaurant D, where only cockroach insecticide delivery, the density decreases by 77.78 %. The difference between two groups has the remarkable statistics significance（ F = 19.25, P〈0.001）. Conclusion Find out the characteristic of the Blattella germanica activities before the measures, then adopt the synthesis measures of prevention and control such as hole-plug and orientation insecticide delivery, the effect is remarkable.
