四种防治措施下韭菜田节肢动物群落结构分析

Analysis of Arthropod Community Structure in Chinese Chives Field under Four Control Measures

韭菜田节肢动物发挥着为韭菜授粉和自然天敌控害的作用,为了解韭蛆防治措施对韭菜田节肢动物种类和数量的影响,本文运用群落生态学原理与方法,系统调查比较了未防治对照区、臭氧水灌溉区、功能作物间作区、化学防控区内主要节肢动物的种类和数量及群落结构。结果表明,韭菜田节肢动物多样性较高,共发现27种节肢动物,其中双翅目昆虫和蜘蛛是主要类群。韭蛆的防治措施对地上害虫的种类、数量没有显著影响,对自然天敌和传粉昆虫影响显著。

Arthropod in Chinese chives fields plays the function of pollination and controlling natural enemies. To understand the impact of control measures for Bradysia odoriphaga larva on arthropod species and quantity in Chinese chive fields,the main arthropod species,populations and community structure were systematically investigated and compared using the principles and methods of community ecology. The no control area,ozone water irrigation area,functional plant intercropping area and chemical area were designed. The results showed that the arthropod in Chinese chives fields had a high diversity. A total of 27 species of arthropods were founded. Diptera and spiders were the main groups. The control measures for Bradysia odoriphaga larva had no significant impact on the species and quantity of pests overground,and had significant impact on the species and quantity of natural enemies and pollinators.
