玉溪烟田昆虫生物多样性调查分析OA

Insects are one of the most important biological communities in farmland.The mutual restriction between natural enemies and pests is the theoretical basis of pest biological control.Farmland insect community is one of the most important communities in farmland ecosystem,and it is also an important biological community affecting agricultural production.Investigating the biodiversity of farmland insect community is helpful to detect the overall change of farmland insect community and evaluate the stability and health of farmland ecosystem.Through the biodiversity investigation and analysis of tobacco fields in different habitats in four counties and districts of Yuxi,it is found that there are significant differences in biodiversity between mountain tobacco areas and dam tobacco areas,forming a set of methods that can detect the biodiversity of Yuxi tobacco fields for a long time,which provides tools and references for biodiversity monitoring and biological control research and promotion in Yuxi tobacco areas.
