摘　　要：目的　通过观察拜灭士蟑螂胶饵对德国小蠊室内、模拟现场和现场的杀灭效果 ,以便对该产品的灭蟑毒效作出评价。方法　按照国标GB/T 173 2 2 .8-1998和GB/T 173 2 2 .11-1998《农药登记卫生用杀虫剂的室内药效评价模拟现场》的有关规定进行了实验室、模拟现场及现场的毒效观察。结果　室内有选择和无选择的 10 0 %死亡时间均为72h ,LT50 分别为 13 .7h和 11.7h ;模拟现场 10 0 %的死亡时间为 10 2h ,LT50 为 2 0 .4h ;现场实验投药量按 0 .8g/m2 和0 .4g/m2 ,3d蜚蠊密度下降率分别为 82 .3 %和 63 .6% ,3 0d蜚蠊密度下降率分别为 99.2 %和 89.0 % ,投药量 0 .8g/m260d的密度下降率为 98.3 %。结论　通过室内、模拟现场和现场的效果观察结果证明 ,拜灭士蟑螂胶饵对德国小蠊具有很好的杀灭效果 ,该产品对蜚蠊具有用量小 ,作用强 ,持效长的特点 ,对人畜使用安全且对环境影响极小 ,适用于幼儿活动场所、高档宾馆及高档电器设备处。Objective To evaluate the effects of a paste bait 'BAIMIESHI'against roach, by laboratory test and in the field application. Methods To test it according to the GB/T 17322.8-1998 and the GB/T 17322.11-1998. Results The results of laboratorial test showed that a 100% mortality was achieved during 72 h by both forced and unforced feeding tests. The values of LT 50 were 11.7 h and 13.7 h, respectively. A 100% mortality was also achieved during 102 h by the analogous field test,and the value of LT 50 was 20.4 h. In the field application, with a dosage of 0.4 g/m 2, the density reduction rate (DRR) came to 63.6% and 89.0% at the 3 rd and 30 th day, respectively, while with a dosage of 0.8 g/m 2, the DRR came to 82.3%, 99.2% and 98.3% at the 3 rd, 30 th and 60 th day, respectively. Conclusion The roach bait 'BAIMIESHI' has been proved to be very effective on roach control with some of features: less amount used, long term residual effect and high safety, it can be used in the plases that children playing, top grade hotels and electrical equipment.
