【目的】探究黑水虻初孵幼虫采用开口料饲喂是否更有利于其后期生长,并研究猪粪与麦麸混合培养料的最适比例。【方法】设初孵阶段采用开口料(全麦麸)饲喂的对照处理及不采用开口料饲喂的试验处理,用猪粪含量分别为 90%、80%、60%、50%的麦麸混合培养料进行饲喂。定期测量黑水虻幼虫的体长、体宽、体重。【结果】对照处理中,黑水虻幼虫体长、体宽、体重的增长随着猪粪含量的降低而逐渐增高,在猪粪含量为 50%时达到最佳。试验处理中,幼虫的生长指标随着猪粪含量的降低呈现先增后减的趋势,在猪粪含量为80%时达到最佳。比较对照处理与相应试验处理,除猪粪含量为 90%的两组差异不显著外,其余整体生长指标均表现为对照处理优于试验处理,且差异显著。【结论】采用开口料饲喂黑水虻初孵幼虫更有利于其后期生长,且粪含量为 50%的猪粪麦麸混合培养料对幼虫生长最有利。 |

【Objective】The study was to investigate the effect of starter feed on the later growth of newly hatched larvae of Hermetia illucens L., and to explore the optimal ratio of mixed compost of pig manure and wheat bran.【Method】Two groups were set: the control group fed with starter feed(whole wheat bran)at initial incubation stage and the experimental group without starter feed but the mixed wheat bran compost with pig manure contents of 90%, 80%, 60% and 50%. In the experiment, the body length, body width and body weight of the larvae were measured regularly.【Result】In the control group, the growth of body length, body width and body weight of the H. illucens L. larvae gradually increased with the decrease of pig manure content, and reached the best when the pig manure content was 50%. In the experimental group, the growth indicators of larvae showed a trend of increasing first and then decreasing with the decrease of pig manure content, and reached the best when the pig manure content was 80%. Except for the 90% pig manure content, the difference between the control group and the experimental group was not significant. The overall growth indicators of the other groups showed that the control group was better than the experimental group and the difference was significant.【Conclusion】It shows that feeding the newly-hatched larvae of the H. illucens L. with starter feed is more conducive to its later growth, and the mixed compost of pig manure and wheat bran is most beneficial to the growth of larvae when the content of pig manure is 50%. |
