抗蚜威(辟蚜雾)。是英国卜内门公司生产的氨基甲酸酯类专化性治蚜农药。其作用机理是对虫体内胆碱脂酶的干扰。在防治烟蚜方面,经云南省农科院烟草所1980年和中国农科院烟草所(地址:山东青州)1984年的试验结果表明,10000倍液(青州所)防治烟蚜效果为97.4％(防后第7天)及12500倍液(云南所)效果为99.1％(防后第10天)。试验证明,该药对瓢虫的成虫和幼虫安全,1000倍液仅有轻微的影响;3000倍液对草蛉的成虫和幼虫伤害很轻,对僵蚜(被蚜茧蜂寄生的蚜体)体内蚜茧蜂的高龄幼虫和蛹,不影响其羽化且繁殖能力正常。目前,有些烟区在不断提高抗蚜威的使用浓度,有的甚至用到1000～2000倍液,这不仅提高了烟叶的生产成本,而且还杀伤了有益天敌。据我们初步调查,使用高浓度抗蚜威主要有两个
Pirimicarb (provision of aphids fog). Is the United Kingdom Bu Neimen company specializing in urethane cure aphid pesticides. Its mechanism of action is the interference of cholinesterase in parasites. In the prevention and treatment of aphids, by the Yunnan Provincial Academy of Agricultural Tobacco Institute in 1980 and the Chinese Academy of Agricultural Sciences Tobacco Institute (Address: Qingzhou, Shandong Province) 1984 test results show that 10000 times the liquid (Qingzhou Institute) to control the effects of tobacco aphid was 97.4% (7 days after the anti-post) and 12500 times (Yunnan) effect of 99.1% (anti-post 10 days). Tests show that the drug on the ladybug adult and larvae safety, 1000 times the liquid only a slight impact; 3000 times on the grass larvae and 3000 times the liquid is very light damage to the aphid (aphid body parasitic aphid) Aphid Braconidae larvae and pupae aging, does not affect its emergence and normal reproductive capacity. At present, some smoke areas are continuously increasing the concentration of pirimicarb, and some even use 1000 to 2000 times of liquid, which not only increases the production cost of the tobacco leaf but also kills the beneficial natural enemies. According to our preliminary investigation, the use of high concentrations of pirimicarb is mainly two
