目的：探讨德国小蠊侵害情况及化学防制效果。方法：用目测法调查侵害情况；喷药前后用粘蟑纸粘捕蟑螂，计算防制效果。结果：单位侵害率为1．06％，房间阳性率为0．23％；12．sndmZ拜虫杀及500mg／m2拜力坦滞留喷洒24小时及1、3、5、7、9周后，密度下降率（％）分别为55．6、90．6、94．3、93．0、88．5、80．6和61．1、95．4、97．7、99．2、97．2、88．9。结论：佛山市德国小蠊侵害率极低；两种药物现场滞留效果达2个月以上。
Objective: To investigate the invasion of Blattella germanica and its chemical control effect. Methods: Investigate the infringement situation by visual inspection; stick cockroach with sticky cockroach paper before and after spraying to calculate the control effect. Results: Unit infringement rate was 1.06%, room positive rate was 0.23%; 12. sndmZ beetle kill and 500mg / m2 Bailey Tan retention spray 24 hours and 1,3,5,7,9 weeks after the density decline rate (%) were 55.6,90.6,94.3,93. 0,88.5,80.6 and 61.1,95.4,97.7,99.2,97.2,88.9. Conclusion: The invasion rate of German cockroach in Foshan is very low. The retention of two drugs in the field is up to 2 months.
