| 摘 要： | 为明确双斑长跗萤叶甲越冬卵的空间分布型,2011年10月采用分层随机抽样法在山西省晋中市的玉米田对土壤中的越冬卵进行调查.通过频次分布检验、聚集度指标的测定、改进的Iwao m*-m回归分析法和Taylor幂法则对越冬卵在土壤中的空间分布型进行了分析,并对聚集均数(λ)进行检验,分析越冬卵聚集的原因.结果表明:双斑长跗萤叶甲越冬卵在土壤中的理论分布型符合负二项分布,各项聚集度指标均满足C＞1、CA＞0、I＞0、k＞0、m*/m＞1,空间分布图式在低密度下为聚集分布,基本成分为单个个体,个体间相互排斥.基本成分的相对聚集度随越冬卵种群密度而变化的速率为3.52m-15.61.种群密度越大,相对聚集度的变化速率也越大,而且聚集的程度随着卵密度的增大而增高.聚集均数(λ)的测定表明,聚集是成虫的产卵习性和田间植被的生长情况、土壤性质、温湿度等环境因子综合作用的结果.双斑长跗萤叶甲成虫主要在近土表的土壤中产卵,在距土表15 cm以上的土壤中,有94.2％的越冬卵分布在距土表0-10 cm的土层中,其中以距土表2-5 cm的土层中的卵量最多,平均每个样点有卵25.56粒,占总数的64.7％,显著高于其他深度土层的卵量.
