摘 要: 以传统饲料配方为对照,测试添加不同用量浮萍(Lemna minor)对黄粉虫(Tenebrio molitor)幼虫生长发育及蛋白、粗脂肪含量等指标的影响。结果表明,黄粉虫幼虫对新鲜浮萍适口性良好;新鲜浮萍投饲比例大于80%,对黄粉虫幼虫的生长发育有阻滞,但对其蛋白、粗脂肪含量无显著影响(P>0.05);以鲜浮萍∶麦麸质量百分比为65%∶35%配置,可使饲料成本降低33.95%,且不影响黄粉虫的饲喂周期、产量和质量。利用新鲜浮萍饲喂黄粉虫幼虫是可行的,通过构建"浮萍-黄粉虫"食物链,可显著降低养殖成本,增加经济效益和生态效益,促进黄粉虫养殖行业发展。 Mealworm( Tenebrio molitor) and duckweed( Lemna minor) are living in high density and breeding quickly and both of them are important bioresource and may play a significant role in agriculture.In order to assess the value of duckweed applied to feed mealworm larva,parallel tests were carried out.The results showed that mealworm larvae feed fresh duckweed well,however if the additive proportion of fresh duckweed was over 80%,the growth of mealworm larvae was impeded although the contents of protein and crude fat in body had no significant difference.When the mass percentage of fresh duckweed and wheat bran was 65% and 35%,respectively,the feed cost of mealworm larvae reduced by 33.95% without effects on the breeding period,harvest yield and quality of mealworm larvae.The study showed that fresh duckweed was feasible to feed mealworm larvae.
