北仑河口自然保护区红树林虫害防治综述

A Review Control of Mangrove Insects in Mangrove Reserve of Beilun Estuary

在对防城港市的北仑河口国家级自然保护区红树林的主要虫害——柚木驼蛾和广州小斑螟生物学特性及危害特点探讨基础上,比较分析整治周边生态环境、物理防治、生物防治、化学防治4种防治措施的效果及不足。从红树林所处的生态环境出发,提出保护红树林陆地生态环境,保护害虫天敌,为鸟类、寄生类昆虫营造适宜的生存环境才是防治害虫的根本。

Based on the research and discussion for biological characteristics and damage features of Hyblaea puera and Oligochroa cantonella,the main pests that cause damage to Mangrove Reserve of Beilun Estuary in Fangchenggang City,this paper comparatively analyzes the effects,applications and disadvantages of four preventive measures：restoration of the surrounding ecological environment,physical control,biological control and chemical control.From the perspective of ecological environment where mangroves grow,this paper holds the view that the roots to prevent pests prove to be the protection for terrestrial ecological environment of mangroves,protection for natural enemies of insect pests,and creating a comfortable living environment for parasitic insects and birds.
