铜污染对昆虫生长发育及繁殖影响的研究进展

铜(Cu)是生物体生长发育所必需的微量营养元素,参与或构成许多含铜酶及含铜生物活性蛋白质,但是过度摄入Cu会对生物体产生危害。Cu中毒由许多因素而定,如物种、遗传、年龄和食物等。在生态系统中昆虫种类多,数量大,分布广,往往会取食、转移和代谢环境中的Cu,从而对自身生长发育及繁殖造成影响。通常表现为发育历期延长,体重下降,体长变短,化蛹率、羽化率、产卵率、孵化率、存活率降低,种群数量减少等。本文以近几年Cu2+胁迫对昆虫生长发育及繁殖影响的研究进行综述。

Research progresses about the effect of Copper pollution on the growth and reproduction of insects

Copper (Cu) is a micronutrient necessary for organisms to grow and develop, participating in or forming many copper enzymes and copper bioactive proteins. However, intaking excessive Cu will be harmful to organisms. Cu poisoning relate to many factors, such as species, genetic, age, and food, etcIn ecosystems, the species of insects is very much, the quantity is big, the distribution is wide, besides, insects tend to be feeding, transfer and metabolism of Cu in environment, then affect their growth and breedingIt often manifests with development period extension, weight loss, body length shorten, the reduce in pupation rate,eclosion rate,spawning rate,hatching rate,survival rate and the decrease in the number of population, etc. This paper summarized the research about the effect of Cu2 + stress on the growth and breeding of insects in recent years.
