摘要
在枣园不同间作管理条件下,对主要枣树害虫群落结构特征进行了分析研究,结果表明,枣园生态系统中植被多样化程度越高,科、种及个体总数的丰富度越大;使用化学农药对科、种及个体总数的丰盛度产生的负面效应较大;各枣园枣树害虫的科、种及个体总数的丰富度随季节变化较为明显,不同枣园间差异显著(P<0.05);不同枣园枣树主要害虫群落的相对丰盛度的时序动态变化规律与气温、食料相关;各枣园主要枣树害虫群落指数的时序动态在不同生长季节有一定的差异,但仅从主要害虫群落指数来评判枣园枣树主要害虫群落的特征与功能是不全面的。
Studies on the structure and characteristics of the pests communities in five different jujube yards are conducted in the suburb of Taigu county. The results show that the more the numbers of plant species, the higher are richness of family and species of the pests in the jujube yard; The abundance of family and species individuals was decreased after using insecticides. The richness of family and species individuals changed with season. There are obvious differences of the number of family and species individuals in five different jujube yards. The season dynamics of relative abundance changed with temperature and food; There are obvious differences of the season dynamics of community index in different jujube yards.
