| 摘 要： | 为探索低龄黄粉虫幼虫饲喂不同饲料对幼虫死亡率、体重、化蛹和发育历期的影响。在温度22~28℃、相对湿度30%~45%的条件下，34日龄前饲喂5%奶粉、10%奶粉、100%麸皮、20%玉米粉、40%玉米粉、60%面粉、100%面粉和100%玉米粉8种饲料，后改饲喂纯麸皮饲料，期间不添加其它饲料或水，分别在34日龄和161日龄调查死亡率和体重，每周检查幼虫的化蛹情况。结果表明，34日龄的幼虫体重和死亡率差异极显著，100%玉米粉死亡率（44.00%）最高、体重（0.677 mg/头）最轻，与其它处理之间差异极显著，5%奶粉死亡率（4.33%）最低、体重（1.804 mg/头）最重；各处理对161日龄幼虫的体重影响差异不显著，5%奶粉、10%奶粉和40%玉米粉的死亡率显著低于其它处理。总之，低龄幼虫期饲喂高蛋白饲料可使幼虫期的死亡率下降，幼虫发育历期略有延长，化蛹时间相对较为集中，但对大龄幼虫的体重影响不明显。

| Abstract: | Effect of different feeds for young larvae on death rate,weight and developmental period were studied in dry conditions.Under the condition of 22-28℃,30%-45% relative humidity,8 kinds of food were supplied for the larvae before the 34 days-age,including 5% milk powder,10% milk powder,100% wheat bran,2% maize powder,4% maize powder,60% wheat flour,100% wheat flour or 100% corn flour,then 100% wheat bran was fed to all Larvae,even no water was added.The death rate and weight of Larva were determined at 34 and 161 days-age,and the number of pupation was determined every week.The results showed that：at 34 day-age,the results showed that the death rate and weight of Larva were significantly different,the death rate of feeding 100% maize powder group achieved maximum （44.0%）,and its weight was minimum （0.677 mgperhead）,while the death rate of 5% milk powder was lowest （4.33%）,and its weight was highest （1.804 mgperhead）.At 161 day-age,the weight of Larva was not significantly different,but the death rate of 5% milk powder,10% milk powder or 100% wheat bran group was significantly lower than other group.In summary,supplementing protein-rich feed would decrease the death rate,elongate slightly the development period,centralize the pupating progress of larvae,but there was not significantly effect on weight of old Larva. |
