目的：探寻有效防制抗性家蝇的药物。方法：用正交试验优选组合法筛选出最佳配方，用微量点滴法测定灭害净与单独使用击倒剂＋致死剂＋增效剂的复配剂对家蝇的ＬＤ５０。结果：灭害净与各简单复配剂的共毒系数为４１０．６。结论：该制剂有显著的增效作用
Objective: To explore effective anti-house-control drug. Methods: The optimum formulation was screened by orthogonal test. The LD50 of housefly was calculated by microdilution method, and the compound of exterminator, lethal agent and synergist alone was used to kill housefly. Results: The co-toxicity coefficient of net extermination and each simple compound was 410.6. Conclusion: The preparation has significant synergistic effect
