摘  要:
【目的】系统调查苜蓿种子田节肢动物群落结构组成。【方法】从苜蓿种子田播种后第1年开始,连续2年对种子田节肢动物群落进行调查,并运用多项群落多样性指标研究节肢动物群落的时序动态。【结果】在苜蓿种子田中发现节肢动物12目58科256种,其中天敌昆虫8目21科,害虫7目27科。种子田节肢动物群落的物种多样性与苜蓿的物候期及田间管理等情况有关,并受环境条件和气候的影响较大。【结论】2010年群落各多样性指标均高于2011年,说明2011年在田间施用化学农药对群落的稳定性产生影响。

摘  要:
【Objective】This project aims to systematically investigate arthropod community in alfalfa seed fields.【Method】The arthropod community in alfalfa seed fields from first year after sowing to the next was investigated. And diversity indices were measured across the season. 【Result】The finding found 256 species in58 families of 12 orders,including insect natural enemies in 21 families of 8 orders,and pests in 27 families of 7 orders. Diversity indices were measured across the season. The results showed that arthropod species diversity was correlated to alfalfa phenology,field management and climatic environment.【Conclusion】In addition,diversity was higher in 2010 than in 2011,which was attributed to application of chemical pesticides in2011.
