重金属镉对棕尾别麻蝇亲代及子代生长发育与繁殖的影响

棕尾别麻蝇Boettcherisca peregrina初产幼虫喂饲含不同浓度Cd2+的饲料直至化蛹时,其亲代的生存、生长发育与繁殖受到了显著的影响.Cd2+处理浓度越高,亲代幼虫、蛹和雌雄成虫的体重越轻,幼虫和蛹的体长越短,化蛹率、羽化率、交配率和产仔量越低,幼虫历期和蛹期越长,成虫寿命越短.但Cd2+处理对成虫性比则无显著的影响.相比之下,经Cd2+处理后雌虫所产的子代若不再经受Cd2+处理时,子代生存、生长发育与繁殖则基本不受影响,说明Cd2+对亲代的影响不能传递至子代.此外,探讨了该蝇亲代与子代体内Cd2+含量在其变态过程中的变化规律.
