不同枣园生态系统中昆虫群落及其多样性

对太谷地区枣园不同生态系统中昆虫群落及其多样性进行了研究。结果表明，在5种类型的枣园昆虫有209种（包括螨类），它们分别隶属于13个目（包括蜱螨目），80个科；不同枣区昆虫群落的科数，物种数及其丰盛度均有不同程度的变化。在不同生境集中性指数也有一定的差异；全年各园的优势和中主要以刺吸式口器的蚧虫为主，偶发性优势种是朱砂叶螨，枣飞象和枣尺蠖；昆虫群落及各类群生态优势集中性在不同枣园及不同季节并不一致。

STUDIES ON THE DIVERSITY AND INSECT COMMUNITY IN DIFFERENT INTERCROPPED AND MANAGED JUJUBE YARD ECOSYSTEMS

The diversity and insect community in different intercropping and managing jujube yard ecosystems in Taigu were studied. The results showed that there were 209 species of insect that belong to 13 order and 80 families in different jujube yard ecosystems in Taigu (including harmful mites). The number of order and species and individual were not the same in different jujube yard ecosystems. In different ecosystems, proportion of principal groups in insect community was different,so that diversity and evenness and dominant concentration index were not the same. Annual dominant species in each jujube yard was insect scales, and sometimes was Scythropus yasumatsui Kono et Morimoto and Sucra jujuba Chu and Tetranychus cinnabarinus (Boisduval). The dominant concentration index of insect community and its principal groups was not the same in different month and jujube yards.
