“强迫接触法”是一种用于测试滞留型杀虫剂对家蝇药效的常见方法。通常是将药物按一定剂量均匀涂布于特定的物体表面(木板、灰墙、玻璃、水泥等),然后取20—30只羽化3—4天的家蝇(各半),放入强迫接触器内,置上述表面进行强迫接触一定时间,以观察药效。以上过程,取试虫是关键,要经过麻醉、计数、恢复等步骤。特别是麻醉不易掌握,麻醉不当对测试结果有很大影响。因此,我们对该方法进行了改
The Forced Contact Act is a common method used to test the efficacy of retention insecticides on houseflies. Usually, the drug is evenly spread on the surface of a specific object (wooden board, gray wall, glass, cement, etc.) according to a certain dosage, and then 20-30 houseflies (halves) that are 3-4 days of emergence are put into forcible contact Device, set the above surface forced contact for a certain period of time, in order to observe the efficacy. The above process, take the test insects is the key to go through anesthesia, counting, recovery and other steps. Especially anesthesia is not easy to grasp, improper anesthesia has a great impact on test results. Therefore, we changed the method
