德国小蠊生态习性与控制效果研究

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。

A Study on Blattella germanica Habitat, Behaviors and Effect of Control

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.
