Methyl Parathion

一种有机磷酸酯杀虫剂；对烟草芽虫幼虫的实验室菌株和田间分离株均有致死性（LD50s分别为7和81.8-128.3μg/g）；在苜蓿田中以0.4磅/英亩的剂量使用时，每100次网扫捕获的臭虫(C.sayi)数量减少；在40μg/ml的剂量下，可增加SCE并在V79中诱导M1期细胞周期停滞；对大鼠有毒（LD50=14mg/kg）。An organophosphate insecticide; lethal to lab strains and field isolates of tobacco budworm larvae (LD50s = 7 and 81.8-128.3 μg/g, respectively); reduces the number of stink bugs (C. sayi) caught per 100 net sweeps when applied to alfalfa fields at 0.4 pounds/acre; increases SCE and induces cell cycle arrest at the M1 phase in V79 at 40 μg/ml; toxic to rats (LD50 = 14 mg/kg).
