摘要
通过在饲料中添加重金属镉(Cd)饲喂棕尾别麻蝇Boettcherisca peregrine的幼虫,研究镉对其成虫繁殖能力和生殖腺发育的影响。结果表明,棕尾别麻蝇幼虫在取食含100μg/g、200μg/g、400μg/g和800μg/gCd2+的人工饲料后,成虫的羽化率和寿命都明显下降;但镉处理对成虫的交配率无显著影响,雌成虫的卵巢含卵量与雌虫是否在幼虫期取食镉有关,雌虫在幼虫阶段接触到的镉浓度越高,含卵量越低。成虫生殖腺的发育也与在幼虫期接触到的镉浓度相关,镉浓度越高,精巢和卵巢的长度就越短,生殖器系数也越小。
For evaluating the effects of dietary cadmium（Cd） on fecundity and gonad development of Boettcherisca peregrine,newly oviposited larvae of the fly were exposed to various administered concentrations in the artificial diet until pupation under laboratory conditions,and some parameters were observed and analyzed.The results indicated that the lifespan and survival rate of adults decreased obviously when they exposed to various concentrations（100,200,400 and 800 μg/g） in their larval stage,but mating rate had no distinct influence.Quantity of eggs containing correlated to the concentration of female adult contacted.If they contacted higher concentration in larval stage,the lower eggs in their ovaries we would found.Moreover,with increasing of dietary Cd concentration,the genital organs coefficient became lighter,the length and width of testis and ovary became shorter.
