全球气候的持续变暖引起了人类的高度关注。农业害虫是关系到农业生产顺利进行的一个特殊的昆虫类群,已经受到温度升高的影响。本文从气候变暖对农业害虫的发生、为害以及与天敌间关系的影响等三方面进行了综述。温度升高导致农业害虫的发生区域扩张,发生期提前和延长,高温适生种群发生量增大;农业害虫的为害时期改变,为害程度加重,为害物种之间产生新的竞争关系;农业害虫与寄主植物、天敌之间的同步性发生改变,继而影响到农业害虫的生物防治。本文最后对当前的研究工作进行了评述,就气候变暖形势下农业害虫的防治提出建议。
The global warming continues to attract the attention of mankind. Agricultural pests are a special group of insects related to the smooth progress of agricultural production and have been affected by the temperature rise. This article reviews the occurrence and damage of agricultural pests from the effects of climate warming on the relations between pests and their natural enemies. The increase of temperature led to the expansion of agricultural pests, the occurrence and extension of the occurrence period, and the increase of the population of high temperature and temperature-suitable populations. The changes of pests in pests, the aggravation of pests and the new competitive relationship among pests occurred. The synchronization between host plants and natural enemies has changed, which in turn affects the biological control of agricultural pests. At the end of this paper, the current research work is reviewed to make recommendations on the prevention and control of agricultural pests under the condition of climate warming.
