【摘要】 在施用金龟子绿僵菌菌剂前后调查了林间节肢动物群落的分布概况,结果表明:林间施菌区的物种总数及群落个体总数均较对照区要略少;垂直分布格局中,灌木层的物种数和多样性指数最大;时序动态分析中,6月份的多样性指数达最大值(1.6683);改善了整个马尾松林节肢动物群落的多样性和稳定性.更多还原

【Abstract】 The distribution of arthopod community was investigated before and after spraying microbial insecticide of Metarhizium anisopliae in the experiment. The results showed that the totals of species and individuals were slightly lower in the sprayed areas than the ones in the CK area. The quantities of species and individuals and the index of diversity of brush and herb layer were the greatest in the vertical distribution pattern. The greatest value of diversity index was 1.6683 during the analysis of time dynamics in June. The diversity and stability of arthopod community in masson pine stand was improved.更多还原
