农田生物多样性对昆虫的生态调控作用

Effects of ecological regulation of biodiversity on insects in agroecosystems

随着农田作物的单一性种植,植食性昆虫暴发、物种流失等问题日益突出,化学农药大量应用于作物有害生物的防治更加剧了对农田生态系统的破坏和不稳定性。因此,从生物多样性-农田生态系统-植食性昆虫的相互关系入手,探讨生物多样性的保护及其在农业有害生物防控上的应用,回归农田生态系统动态平衡的生态调控举措,成为可持续发展农业领域中研究的焦点之一。本文综述了农田生物多样性对昆虫生态影响的重要性及其生态功能,进一步阐述了农田生物多样性在农业生产中的应用及前景。

With the serious problems of herbivorous insect outbreaks and species extinction caused by monocultured crops in large areas,the wide and heavy use of chemical pesticides has made the destruction and instability of agroecosystems to rise.Thus,based on the relationships among biodiversity-agroecosystem-herbivorous insect,studying the impacts of conservation and application of biodiversity on pest control and developing new techniques for ecological manipulation in agroecosystems have become the highlights of research on sustainable agriculture.This paper reviewed the importance and ecological effects of biodiversity on herbivorous insects in agroecosystems,and the prospects and applications of biodiversity in agricultural cultivation was further discussed.
