1988～1991年,用8种杀虫剂在大田和室内进行了防治烟蚜的试验.结果表明,30%乙酰甲胺磷(600ppm),2.5%溴氰菊酯(12.5ppm),50%甲胺磷(1000 ppm)和50%抗蚜威(166.7ppm),田间防治效果均达90%～100%,其残效期为6～10d.雨天防治效果,则乙酰甲胺磷和甲胺磷明显优于其它药剂.但甲胺磷为剧毒农药,一般应禁止在烟地使用,必要时至多在烟苗移栽初期使用1次.25%杀虫双(1250ppm)、5%氯氰菊酯(33.3ppm)和20%杀灭菊酯(100ppm)的平均防治效果均低于70%,故应尽量避免使用.各种农药在烟田对烟叶产生药害的最小浓度(ppm)为甲胺磷7374.8,乙酰甲胺磷6000.0,杀虫双3962.0,溴氰菊酯66.9,氯氰菊酯267.5,杀灭菊酯802.6.

Field and laboratory experiments on the control of aphids Myzus persicae (S.) with some insecticides were conducted in 1988～1991. The results showed that the killing effects of 30% acephate (600 ppm), 2.5% decamethrin (12.5 ppm), 50% tamaron (1000 ppm), 50% pirimicarb (166.7 ppm) were 90%～100%.The residual effects were kept for 6 to 10 days, when spraying was conducted in rain, the killing effects of 50% tamaron and 30% acephats were much better than that of the others. But tamaron, a fatal poison to human being, is generally forbidden to use...
