喹硫磷是一种广谱性有机磷杀虫螨剂,化学名称为0,0-二乙基-0-(2-喹恶磷)硫代磷酸酯,分子式C_(12)H_(15)O_3N_2PS,分子量298.3。纯品为白色无味结晶,水中的溶解度为22ppm(24℃),易溶于苯,二甲苯、乙醚、醋酸乙酯、丙酮及乙醇中,遇碱则分解。喹硫磷具有胃毒、触杀作用,兼有杀卵效果,无内吸性,对植物渗透性强,残效期1-2周。据国外报导,喹硫磷对蚜、螨、叶蝉、粉虱、蚧虫、蓟马、稻瘿蚊、蚱蜢、棉铃虫、红铃虫、金刚钻、棉铃象、跳蠉(虫甲)、菜青虫、小菜蛾、稻螟、粘虫、地老虎以及苹果蠹蛾等多种害虫,都有良好的防治效果。 杀卵作用:喹硫磷的杀卵作用优良,对鳞翅目昆虫的卵尤为突出。室内以100、200、400ppm浸渍虫卵。
Quetiapine is a broad spectrum organophosphate insecticide with the chemical name 0,0-diethyl-0- (2-quinophthalil) phosphorothioate, formula C 12 H 15, O_3N_2PS, molecular weight 298.3. Pure white tasteless crystal, water solubility of 22ppm (24 ℃), soluble in benzene, xylene, ethyl ether, ethyl acetate, acetone and ethanol, the case of alkali decomposition. Quetiapine with stomach poisoning, contact action, both oviposition, no systemic absorption, permeability to plants, residual 1-2 weeks. According to foreign reports, quetiapine against aphids, mites, leafhoppers, whiteflies, scale insects, thrips, rice gall midge mosquitoes, grasshoppers, cotton bollworm, pink bollworm, diamonds, boll elephant, hopper Pest insects, diamondback moth, rice stem borer, armyworm, to tiger and codling moth and other pests, have good control effect. Ovicidal effect: Quetiapine good ovicidal effect on Lepidoptera eggs is particularly prominent. Indoor 100,200,400 ppm impregnated eggs.
