枣顶冠瘿螨又称枣上瘿螨和枣叶锈螨,是我国枣树上的主要害螨。近年来,在我区枣树(园铃大枣)上发生较重,被害株率达80%以上,致使叶片灰白、增厚、卷曲、变脆,影响叶绿素的形成,减弱光合速率,降低枣产量和品种质量。1988～1991年作者对该虫发生规律及防治进行了研究和试验示范,取得了较好的效果,现报道如下。 Jujube crown crown mites, also known as jujube scabies and jujube leaf rust mite, jujube is the main pest mites. In recent years, jujube (jujube orchardbell jujube) occurred heavier in our district, with more than 80% of infected plants causing the leaves to become gray, thick, curly and brittle, affecting the formation of chlorophyll, decreasing the photosynthetic rate and decreasing the jujube Yield and variety quality. From 1988 to 1991, the author carried out researches and experiments on the occurrence and prevention of the insects and achieved good results. The results are reported as follows.
