摘要
1987—1988年,在陕西省西部及北部烟区观察了烟蚜自然种群数量动态、取食行为特点.用3种缓释杀虫剂进行药效试验.观察发现,烟蚜于5月中旬迁入蚜田,7～8月为数量高峰期;烟蚜大多数(占总蚜量的80～96%)分布在烟株上部第1至第6片叶上,且以背面为多。药剂试验表明,用羊毛脂与50%抗蚜威配制成的缓释剂杀蚜效果最好。
In 1987—1988 studies were conducted on population dynamics,fe-eding behaviour and control trials of three kinds of slow-release insectici-des of the Myzus persicae in west and north Shanxi.the results show thatthe aphids migrate to tobacco plants in the second ten days of May,andthier population are high in July and August.Most of the aphids(account for 80-96% of total)distribute on the 1th-6th top-leaves of tobac-co plant,and more on the back of leaves.The insecticides control shows thatthe effect of the slow-release insecticide made up with wool fat and 50%Pirimicarb for control of aphid is the most effective.
