补充资料:摇蚊幼虫
双翅目昆虫摇蚊科幼虫的总称。全世界已鉴定的约3500种。
摇蚊幼虫由头部和13个体节组成,前3节为胸部,其余为腹部。幼虫第一胸节腹前方和腹部末节端部各有一对有趾钩的原足,分别称为前原足和后原足。两后原足之间,有2~3对肛鳃。幼虫的呼吸系统为闭合式无气门型,通过体壁(及鳃)在水中进行气体交换。
摇蚊为完全变态,一年繁殖1~2代。卵、幼虫和蛹生活在水中,成虫营空中生活。摇蚊幼虫可生活在各种水体中,以淡水湖泊和河流的水体底部或水生植物间为多。摇蚊幼虫是经济鱼类的重要饵料,也是摇蚊的越冬虫态。
在环境生物学的研究中,摇蚊幼虫被广泛应用于生物监测。摇蚊属(Chironomus)的种类耐有机物污染;前突摇蚊属(Procladius)的种类耐重金属污染;双线环足摇蚊(Cricotopus bicinctus)的幼虫对电镀废物包括六价铬、氰和铜离子的耐受量特高。摇蚊幼虫对污染的适应范围和作用机制,有待进一步研究。
