摘  要：
为研究不同金属离子对黑水虻幼虫生长的影响及在虫体和虫粪中的积累分布规律,通过在黑水虻幼虫饲料中加入不同浓度的Cu~(2+)、Zn~(2+)、Cd~(2+),分析观测了幼虫增重、虫体和虫粪中金属含量等情况。结果表明,适量的Cu~(2+)、Zn~(2+)、Cd~(2+)可以促进黑水虻幼虫的生长,Zn~(2+)浓度在400 mg/kg时黑水虻幼虫的体重最高。Cu~(2+)、Zn~(2+)、Cd~(2+)在黑水虻幼虫体内和虫粪中的残留随着饲料中Cu~(2+)、Zn~(2+)、Cd~(2+)浓度的升高而增加。Cu~(2+)、Zn~(2+)在虫体中的残留比例都小于50%,大部分残留在虫粪中,Cd~(2+)在10、20、40 mg/kg处理中虫体的残留比例大于50%,最高达到了91.3%,而在80、160 mg/kg处理中虫体残留量比例小于50%。各重金属在虫粪中的残留主要以残渣态存在,且各形态的含量顺序在高浓度处理中都为残渣态>酸溶态>水溶态>碱溶态。说明饲料中适量金属离子的添加有利于黑水虻幼虫生长,但过量的添加会抑制黑水虻幼虫生长,并造成金属离子的积累。

摘  要：
In order to study the effects of metal ions on the growth of black soldier fly larvae and the accumulation distribution in larvae and feces, the larvae breeding experiments with different concentrations of Cu~(2+), Zn~(2+), Cd~(2+) in the feed were done by analysising the indexes of larval weight, metal content in larvae and feces. The results showed that the appropriate amount of Cu~(2+), Zn~(2+), Cd~(2+) could promote the growth of the larvae. The larvae weight was the highest under concentration of Zn~( 2+)400 mg/kg. Residues of Cu~(2+), Zn~(2+) and Cd~(2+) in the larvae and feces were increased with increasing of the concentration of Cu~(2+), Zn~(2+), Cd~(2+) in the feed. The residues of Cu~(2+) and Zn~(2+) in larvae were less than 50%, but most of them remained in feces. The Cd~(2+) residue ratio of larvae was more than 50%, the highest ratio was 91.3% under 10, 20 and 40 mg/kg treatments, while the Cd~(2+) residue ratio of larvae was less than 50% under 80 and 160 mg/kg treatments. The residues of heavy metals in feces mainly existed in residual state, and the order of contents in each form was residual state > acid soluble state > water soluble state > alkali soluble state under high concentration. These indicated that the addition of appropriate metal ions in feed was beneficial for the growth of the larvae, but excessive addition would inhibit the larvae growth and cause the accumulation of metal ions.
