| 中文摘要: |
| 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5 d体重增长9433倍，从第6 d至第10 d体重增长7倍，最后10 d体重增长095倍，从初孵幼虫到老熟幼虫体重增长148667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=143 g/百头虫）与第10 天（W=1145g/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2888%。 |

| The development rate and food conversion efficiency of Hermetia illucens feeding on peanut residue were measured at the laboratory (T=30℃，RH=60%). Results indicated that 3 types of developmental patterns were identified: larvae body weight was exponentially increased (9433 fold) in first 5 d, linearly increased (7 fold) from sixth to tenth day and logarithmically increased (095 fold) in last 10 d Totally 148667 fold of body weight accumulation were found when larvae fed on peanut residue in 20 d The trend of larvae body increasing was described by Logistic pattern with two inflexion point: larvae body increased on fifth and tenth day were W=143 g/100 larvae and W=1145 g/100 larvae, respectively Food conversion efficiency of Hermetia illucens feeding on peanut residue was 2888% |
