摘要：

为了研究镉(Cadmium,Cd)和铜(Copper,Cu)在棕尾别麻蝇Boettcherisca peregrina(Diptera:Sarcophagidae)生长发育过程中积累和排泄的动态变化,在室内给棕尾别麻蝇初产幼虫连续饲喂含不同浓度Cd2+或Cu2+的人工饲料,每隔24h测定幼虫对Cd2+或Cu2+积累和排泄及变态过程中的变化。结果表明:棕尾别麻蝇幼虫取食含有Cd2+的饲料后,大部分Cd2+积累在体内,少部分通过排泄系统排出。Cd2+在幼虫体内的积累量随着取食时间的延长而增加,幼虫取食含200μg/gCd2+饲料后,体内Cd2+积累量高于取食含100μg/g、400μg/g和800μg/gCd2+饲料后体内Cd2+积累量,幼虫对Cd2+排泄量亦有相同的规律。Cd2+在幼虫、蛹和刚羽化成虫中的含量依次降低。棕尾别麻蝇幼虫取食含Cu2+的饲料后,其体内Cu2+积累量小于排泄量,而且体内积累量和排泄量随着取食时间的延长而增加,Cu2+积累量和排泄量与取食饲料中的Cu2+浓度均不成正比。在变态过程中,Cu2+也不断被排泄,体内Cu2+含量随之下降。

摘要：

For studying the dynamical variations of accumulation and excretion of cadmium and copper in Boettcherisca peregrine (Diptera:Sarcophagidae) during growth and development,newly oviposited larvae of the fly were exposed to different concentrations of Cd2+ or Cu2+ administered in the artificial diet under laboratory condition,and the accumulation and excretion of Cd2+ or Cu2+ by the larvae every 24 h and changes in the metamorphosis were measured. The results showed that the larvae fed on diets supplemented with Cd2+ retained most of ingested Cd2+, only few ingested Cd2+ were excreted by excretory system. Cd2+ accumulation in larvae of B. peregrina increased with the prolonging of feeding time, but was not proportional to Cd2+ concentration in diets. Cd2+ accumulation in larvae at 200 μg/g exposure was higher than that in larvae at 100 μg/g, 400 μg/g and 800 μg/g Cd2+ exposure. Cd2+ excretion of the larvae showed the same tendency. During metamorphosis, Cd2+ contents in the pupae was lower than that of in the larvae, newly eclosion adults had lower Cd2+ contents than the larvae. After B. peregrina larvae fed on diets supplemented with different concentrations of Cu2+, Cu2+ contents retained in the larval body were less than that excreted by excretory system. Cu2+ accumulation and excretion of B. peregrina larvae increased with the prolonging of feeding time, and Cu2+ accumulation and excretion were not in direct proportion to Cu2+ concentrations administered in the artificial diet. During metamorphosis, Cu2+ was excreted continually and Cu2+ content in vivo decreased.
