摘要
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。
Global warming has caused great concerns.Agricultural insect pests are affected by elevated temperatures.Here we reviewed the effects of climate warming on the occurrence,the damage as well as the interactions between the agricultural insect pests and natural enemies.For one thing,temperature elevation may lead to geographic distribution expansion of agricultural insect pests,change in phenology,and the outbreak of high-temperature adapted species;for another,global warming changes the damage period of insect pests,aggravates its damages and brings new competitions among pests.The phenological synchrony between agricultural insect pests and its host plants or natural enemies may be changed owing to increased temperature,which thus alters the insects occurrence and biological control.At the end of this review we summarized the current researches and discussed the biological control of agricultural insect pests under the circumstances of global warming.
