为充分利用天敌昆虫大面积综合防治大豆蚜虫,对牡丹江丘陵半山区大豆蚜天敌昆虫种类及动态进行了研究。结果表明:牡丹江丘陵半山区大豆蚜优势天敌主要有草蛉、食蚜蝇、瓢虫和寄生蜂(僵蚜)。各优势天敌主要出现在大豆蚜的发生初期(6月末7月初),高峰期出现在大豆的花期(7月中旬左右),消失于大豆成熟初期。而天敌种群以草蛉出现最早,其次是瓢虫。天敌种群的动态变化随着大豆蚜虫发生量变化而变化。
為充分利用天敵昆蟲大麵積綜閤防治大豆蚜蟲,對牡丹江丘陵半山區大豆蚜天敵昆蟲種類及動態進行瞭研究。結果錶明:牡丹江丘陵半山區大豆蚜優勢天敵主要有草蛉、食蚜蠅、瓢蟲和寄生蜂(僵蚜)。各優勢天敵主要齣現在大豆蚜的髮生初期(6月末7月初),高峰期齣現在大豆的花期(7月中旬左右),消失于大豆成熟初期。而天敵種群以草蛉齣現最早,其次是瓢蟲。天敵種群的動態變化隨著大豆蚜蟲髮生量變化而變化。

The species and population dynamics of natural enemies of soybean aphid in hilly semi-mountainous region of Mudanjiang city were studied to prevent soybean aphid in large area synthetically. The results showed that the advantaged natural enemies were lacewings, syrphus flies, ladybird, parasitic wasps (stiff aphid). The main advantaged natural enemies of soybean aphid occurred early at the end of June and early of July,the peak appeared at flowering stage of soybeans(mid July), disappeared in the early maturity stage of soybeans. The natural enemies appeared the earliest was lacewings, followed by ladybird. The dynamics of natural enemy population changed with the amount of soybean aphid.
