2014-2015年,调查研究了成都地区黄秋葵蚜虫发生特点、其天敌资源种类和优势天敌类群发生动态,发现成都地区为害黄秋葵的蚜虫主要是棉蚜,其天敌资源有5目8科21种,优势种有棉平突蚜茧蜂、异色瓢虫、龟纹瓢虫和大草蛉。棉蚜发生量在黄秋葵移栽40d即达到高峰期,后逐渐下降,棉平突蚜茧蜂发生动态与棉蚜的发生动态具有较强的跟随关系,瓢虫、草蛉和食蚜蝇的发生动态差异较大,与棉蚜的发生动态跟随关系不明显。
In 2014-2015, the occurrence characteristics of Aphis gossypii in the area of Chengdu were studied. The species of natural enemies and the predominant natural predators occurred in Chengdu area. The aphids in Okra were predominantly cotton aphid in Chengdu. The natural enemies resources were 21 species, 5 orders, 8 families and 5 dominant species A species of cotton-tipped aphid Braconidae, Harmonia axyridis, ladybug and ladybug. The occurrence of Aphis gossypii reached the peak 40 days after transplanting, and then decreased gradually. The occurrence of Aphis gossypii had a strong follow-up relationship with that of Aphis gossypii. The occurrence of ladybug, The difference is not obvious with the dynamic follow-up of cotton aphid.
