摘要
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。
This PaPer reported that in Foshan urban area, the unit infestation rate of Blattela germanica was 1. 06%, while the room infestation was 0. 225%. It showed that the Blattela germanica infested mainly in large or medium specific trade.12. 5mg ai/m2 of respansar and 500 ai/m2 of Blattanex were used in the field test for controlling the Blattela germanica. A residual spray was given and observed for 24 hours,one.rbe wed, five weeks, seven week and nine weeks later, the decedng rate was 55. 6 %, 90. 6 %,94. 3%, 93.0%, 88. 5%, 80. 6% and 61. 1 %,95. 4%, 97. 7%, 99. 2%, 97. 2%, 88.1 9 % reSPectively. The residtal effect was more than two months.
