温度对水稻害虫稻飞虱的影响研究

Influence of Temperature on Rice Planthopper

稻飞虱是为害水稻的一类重要的迁飞性害虫,近年来,稻飞虱在东南亚、中国、韩国和日本等亚洲国家、地区稻区暴发频次增加以及为害程度加重,水稻产量大幅度下降。而全球变暖已是一个公认的事实,我国是全球变暖最明显的区域之一,稻飞虱作为全国重要的经济害虫,会对全球变暖做如何响应?本文阐述了温度对稻飞虱种群消长和危害规律的影响,了解升温对稻飞虱发生的影响对其预测预报和防治具有重要的意义。

Rice planthopper is a kind of important migratory pests of rice. In recent years, rice planthopper in rice region in Southeast Asia, China, South Korea and Japan outbreak frequency and damage degree are increased, and rice yield is greatly decreased. And global warming is already an accepted fact; China is one of the most obvious regional global warming. Effect of temperature on planthopper population dynamics and damage regularity were expounded. Understand effects of temperature on rice planthopper in pest forecast and control is of great significance.
