一般药效测定的步骤可分室内测定与田间试验两部分。室内试验的优点是观察细致,试验材料及环境容易控制,药效高低容易比较。因此一般先在室内进行测定效果,选择有效的农药再进行浓度试验。确定有效浓度后,再在田间试验作最后鉴定,得出结论从而推广应用。如单纯依靠田间试验,一方面由于工作量大不能同时进行很多处理,同时因田间试验环境不易控制,虫数分布不均,特别对活动性强的昆虫难以 The general method for determining the efficacy of pharmacological tests can be divided into two parts and field tests. Indoor test has the advantage of careful observation, test materials and the environment easy to control, easy to compare the level of efficacy. Therefore, generally the first determination of the effect indoors, select the effective concentration of pesticides and then tested. After the determination of the effective concentration, and then in the field test for the final identification, draw conclusions so as to promote the application. Such as simply relying on field experiments, on the one hand due to heavy workload can not be a lot of processing at the same time because of field test environment is not easy to control the uneven distribution of insects, especially insects and activity is difficult
