田间调查表明,绿豆上的蚜虫主要为豆蚜AphiscraccivoraKoch。其发生规律与绿豆生育期密切相关:1~3复叶期,豆蚜迁入绿豆田,始花期蚜量增长最快,盛花至初英期蚜量最大,为害最重,盛荚期后蚜量迅速下降。防治策略为前期加强栽培管理,促进植株健壮生长,中期辅以药剂防治,后期充分利用天敌的自然控制作用。药剂防治以40%氧敌乳油1500倍液,盛花期施用1次即可控制其为害。
Field surveys showed that aphids on mung bean are mainly Aphiscraccivora Koch. The law of its occurrence was closely related to the growth stage of mung bean. During the period of 1 to 3 foliage, the bean aphid moved into the mung bean field, and the amount of aphid rose sharply at the beginning of flowering stage. The amount of rapid decline. Prevention and control strategies for the early strengthening of cultivation and management, and promote robust plant growth, supplemented by pesticides in the medium-term control, the natural enemies at full use of natural control role. Pharmacy control with 40% oxygen enemy EC 1500 times, full bloom flowering once can control the damage.
