林业的病虫害防治一直是我国减灾工程的重点性工作之一,林业病虫害严重阻碍了林业的发展,林业病虫害的治理工作也越来越受到人们的广泛关注。人们发现,单纯的使用化学药剂不但成本较高,长期使用化学药剂对于树木损伤较大,有时对部分有益种群形成威胁,部分害虫容易产生抗药性,因此,本文提出利用生物防治的手段进行林业病虫害的防治。利用生物手段进行林业病虫害防治优势突出,本文针对目前林业病虫害现状,给出了生物防治的几种方法,希望对林业病虫害的防治有所帮助。
Prevention and control of pests and diseases in forestry has always been one of the key tasks of disaster reduction in our country. Forestry pests and diseases have seriously hampered the development of forestry and the control of forestry pests and diseases has drawn more and more people’s attention. It has been found that the simple use of chemical agents is not only costly, but also long-term use of chemical agents can damage trees more and more, sometimes threaten some beneficial populations, and some pests tend to develop drug resistance. Therefore, this paper proposes to use biological control measures for forestry pests and diseases Prevention and treatment. The advantages of using biological means to control pests and diseases of forestry are outstanding. In this paper, according to the current situation of forestry pests and diseases, several methods of biological control are given, hoping to be helpful to the prevention and control of forestry pests and diseases.
