保幼激素类似物对蝇蛆杀灭效果观察

Study on Efficacy of Insect Growth Regulator，S-31183,to Housefly Larvaes Control

笔者应用昆虫生长调节剂──保幼激素类药物（S─31183）颗粒剂，对蝇蛆进行杀灭试验。结果：对家畜粪便及居民生活垃圾类型蝇孳生地具有良好控制效果，当施药剂量100mga.i／m^2时，有效抑制蝇蛆羽化达28天。相同剂量单独施药，垃圾堆放点的成蝇密度下降缓慢；若配合诺毕速灭松（225mga·i／m^2)空间超低容量喷洒；可使成蝇密度迅速下降，并控制在低水平达35天。

The study reported the residual effect of S-31183 0.5G to houseflies control on site of accumulation of animal excrement and garbage dumpes by method of larval isolation and fly count on available surfaces respectively.S-31183 0.5G against housefly larvaes provided effective inhibition of emergence for 28 days at 100mg a.i／m^2 on the site of accumulation of animal excrement.The housefly density was slowly decreased on the garbage dump after treatment with S-31183 at 100mg a.i/m^2.However,it was quickly and enduringly controlled at low level on another dnmp after treated with S-31183 combined with an adulticide space spray.
