    摘要:

    选择有代表性的10个白蜡主产地,研究了各地白蜡虫天敌群落的物种组成和群落结构,并进行了聚类分析和排序。结果表明,白蜡虫泌蜡期天敌群落共有捕食和寄生性天敌18种,各群落的优势种和物种组成变化较小,群落相似性程度较高,相似性系数最高达95.12%,最低为73.86%。影响群落相似性的主要因子为产区、地理位置、捕食性瓢虫的种类和数量。每一群落有3~4种优势种天敌,导致白蜡虫天敌群落的优势度集中指数较低,多样性指数和均匀性指数较高。通过聚类分析和排序,将白蜡虫天敌群落分为3类:第1类为种虫产地;第2类为白蜡产地;第3类虫蜡皆产。3种类型的寄生性天敌优势种种类相同,但数量变化较大。捕食性天敌的种类和危害有很大区别。

    Abstract:

    The natural enemy communities of white wax insects were investigated in 10 main production areas in the period of secreting white wax.The results showed that there were 18 species of natural enemies in the communities.The highest coefficient of community similarity was 95.12%,and the lowest coefficient was 73.86%.The main factors interfering with community similarity were producing area,geographical region,species and quantites of predacious ladybirds.There were 3~4 dominant species of natural enemies in on...
