摘要
为了提高枣树害虫综合防治,采用系统调查方法,对太谷地区不同管理模式下枣园的刺吸式口器害虫群落进行调查与分析。结果表明,在不同管理条件下,粗放管理枣园(Ⅰ)刺吸式口器害虫个体数和优势种数均大于精细管理枣园(Ⅱ);枣园寄主植物丰富度直接影响刺吸式口器害虫群落结构组成与时间动态,但2种枣园刺吸式口器害虫生物多样性(均匀度、优势度)各自的季节变化规律均趋于稳定,说明枣园管理方式不会改变刺吸式口器类害虫在夏秋季节的生物的多样性。因此,在枣树刺吸式口器害虫防治工作中,仅依靠生物防治见效甚微。应在害虫猖獗时,适当结合化学防治,以利于控制虫害发生与发展。
In order to improve the integrated prevention of pest insects in the jujube yard in Taigu County, pest insects with sucking mouthparts were investigated and analyzed. It was showed that the dominance and individuals of pest insects with sucking mouthparts in extensive management jujube yard （ Ⅰ ） were more than those in fine management jujube yard （ Ⅱ ）, community composition and temporal dynamics of pest insects with sucking mouthparts in jujube yard were impacted directly by host plant, but variation of biological diversity of pest insects with sucking mouthparts in two kinds of jujube yards had steady seasonal change respectively. Management would not change the biodiversities especially in summer and autumn. So there was insects with sucking mouthparts. An appropriate sucking mouthparts when they were rampant. of pest insects with sucking mouthparts in different season, little effectiveness relying on biological controlling for pest chemical controlling should be applied to pest insects with
