摘要
全球气候变化日益加剧,给昆虫等变温动物的发育和繁殖带来巨大影响,进而影响其种群动态分布甚至物种生存。蝗虫作为世界上最重要的农业害虫种类之一,对于温度等气候变化非常敏感,其种群动态及成灾程度与温度变化密切相关。近年来,除了低温耐受性,蝗虫对高温的耐受能力也很强。成虫的致死温度高达40℃左右。在短时高温下,蝗虫可以通过体内抗逆物质及酶含量的变化机制、不连续气体交换循环呼吸代谢模式以及体温调节行为来避免机体受到损伤,甚至短时高温往往有利于蝗虫交配。蝗虫自身的体温调节行为,在其适应环境和抵御病菌方面起着关键性作用,大大增加了蝗虫的生存能力。该文综述近年来蝗虫对高温耐受性的研究进展,加深全球气候变暖背景下对蝗虫种群发生规律的认识。
Global climate change has a great impact on the development, growth and reproduction of insects and other heterothermic animals, which affects their population dynamics, distribution and even survival. Locusts, as one of the most important agricultural pests in the world, are very sensitive to climate change, especially global warming. There is a close correlation between population dynamics, outbreak and temperature change. In recent years, more and more researches have focused on the hightemperature tolerance of locust adults. The lethal temperature of locust adults is as high as about 40℃.Under short-term environmental high temperature, locusts can avoid body damage through the accumulation of stress resistant substances and enzyme content, the change of discontinuous gas exchange cycle(DGC) respiratory metabolism mode, and thermoregulation behavior. Short-term high temperature is often conducive to locust mating. Thermoregulation behavior of locusts plays a key role in their adaptation to the environment and resistance to bacteria, which greatly increases the locust’s viability. Here we summaried recent research progresses in locust high-temperature tolerance, which helps to understand the outbreak of locust disaster and its sustainable management in the context of global warming.
