| 摘 要： | 为明确食物中重金属离子在蜘蛛体内的传递、生物放大及对其生长历期和耐饥力的影响,采用原子吸收光谱法检测了拟水狼蛛Pirata subpiraticus取食加Cd2+食物后体内Cd2+含量变化情况,测定了 Cd2+对其发育历期和耐饥力的间接影响.结果表明:食物中的Cd2+能够通过食物链进行传递并在拟水狼蛛体内积累,积累量随...

| Abstract: | In order to explore the effects of heavy metals on transfer,biomagnification and developmental duration in spiders,the changes of cadmium content in various instars of Pirata subpiraticus fed with Drosophila melanogaster flies reared on artificial diets were detected by atomic absorptions spectrometry and indirect effects of cadmium on its developmental duration were measured.The results showed that excessive cadmium in food could be transferred by food chain and accumulated in P.subpiraticus and the accumu... |
