摘要
一些樱桃花芽只增大而不开花结果,最后干枯,是由桃拟生瘿螨Cecidophyopsis persicae Kuang et Lu为害造成的。桃拟生瘿螨属蜱螨目瘿螨科。在甘肃成县小川镇普遍发生,被害株率为86.8％;花芽被害率87年为10.9％,88年达19.6—22％,经我们广泛深入的调查发现:瘿螨为害的严重程度和以下几种因子有关;①与树体受光强弱呈负相关。②结果后与树龄大小无关,而与樱桃种有关,据初步调查,只为害红樱桃,而不为害岩樱桃。通过对该瘿螨的为害习性和被害后症状明显的特点观察,我们只采取经济、简便的剪除被害花芽的防治方法,防效达99％。
A disease of cherry buds caused by Cecidophyopsis persicae Kuang et Lu has not been reported before. In this paper, the symptoms of this disease were described and its ontrol method was presented.
