灰飞虱再猖獗研究进展及其防治

Research Progress and Prevention on the Resurgence of the Small Brown Planthopper

灰飞虱是一种重要的农业害虫,通过直接刺吸和传播病毒对水稻生产造成很大的影响。从灰飞虱再猖獗的形成机制以及再猖獗的防治方法两方面进行了综述,并推测该虫的再猖獗是毒理学、生理学和生态学综合作用的结果,可以通过农药科学使用、生物防治和提高作物抗虫性等来控制灰飞虱的再猖獗。

The small brown planthopper, Laodelphax striatellus（Fallén）, is one of the important agricultural insect and it can do great harm to rice by piercing and sucking directly or as vector in spread of viruses. This paper gave an overview on the resurgence mechanism and control of the small brown planthopper, and it was predicted that ecotoxicology physiology and ecology of the insecticide were the factors causing the resurgence. It was thought that reasonable use of insecticide, biocontrol and increasing the plant resistance to insects were taken in control of the resurgence of the small brown planthoppers.
