Abstract
本文研究了黑水虻Hermetia illucens幼虫取食花生麸的发育速率及其食物转化率.仔细考察了黑水虻卵孵化后,其幼虫平均体重的增长情况,结果显示,黑水虻在实验条件下(T =30℃,RH=60%),幼虫发育的参考周期为20 d,其中最初5d体重增长94.33倍,从第6d至第10 d体重增长7倍,最后10 d体重增长0.95倍,从初孵幼虫到老熟幼虫体重增长1486.67倍,发育期内的体重增长趋势类似于逻辑斯谛曲线,而第5天(W=1.43 g/百头虫)与第10天(w=11.45g/百头虫)则为逻辑斯谛曲线的两个拐点.食物转化率测定结果表明,黑水虻幼虫取食花生麸的转化率为28.88%.
