| 摘 要：【目的】为了解黑水虻（Hermetia illucens L.）杂种是否具有生长优势，对武汉株与Bioforte株的杂交后代及武汉株、Bioforte株的生长性能差异进行研究。【方法】黑水虻武汉株与Bioforte株经杂交和横交分别获得试验株F和 F′，测定和比较F、 F′黑水虻和武汉株、Bioforte株黑水虻的各项生长性能指标，以及羽化时间、产卵时间等性状。【结果】F和F′黑水虻的羽化时间为30.3 d、35.3 d，产卵时间为36.6 d、40.3 d；F黑水虻的羽化、产卵时间均比武汉株短5 d、均比Bioforte株短9 d；F′黑水虻的产卵时间均比武汉株短1.4 d，羽化时间比Bioforte株短4.0 d，产卵时间比Bioforte株短5.4 d。在饲料利用方面，F、F′、武汉株、Bioforte株黑水虻的表观消化率为59.53%、59.25%、58.05%、58.10%，饲料利用率为4.11%、4.58%、3.41%、3.74%，料重比为8.58、7.78、10.5、9.05。与武汉株和Bioforte株比较，结果表明，F黑水虻的表观消化率显著高于武汉株和Bioforte株，羽化时间及产卵时间显著低于武汉株和Bioforte株；F′黑水虻的饲料转化率、表观消化率、饲料利用率显著高于武汉株和Bioforte株，料重比及蛋白质含量显著低于武汉株和Bioforte株；F、F′黑水虻的产卵数、卵块质量、孵化率与武汉株和Bioforte株均无显著性差异。【结论】F、F′黑水虻在饲料利用上优于武汉株与Bioforte株，但蛋白质含量略低于两者；F、F′黑水虻的产卵数、卵块质量、孵化率能较好地保持在武汉株和Bioforte株的水平上；F黑水虻在生长周期上具有优势，其羽化时间与产卵时间均比武汉株与Bioforte株短。 |

| Abstract: 【Objective】 In order to study whether hybrids of the black soldier fly（Hermetia illucens L.）have growth advantages. The hybrid offspring of Wuhan strain and Bioforte strain and the difference of growth performance between Wuhan strain and Bioforte strain were studied. 【Method】 Experimental strains F and F′ were obtained by cross and transverse cross between Wuhan strain and Bioforte strain,respectively. The growth performance， eclosion time and oviposition time of F and F′, were measured and compared with those of Wuhan strain and Bioforte strain. 【Result】 The eclosion time of F strain and F′strain was 30.3 d and 35.3 d, and the oviposition time was 36.6 d and 40.3 d,respectively. The eclosion and oviposition time of F strain were 5 d shorter than that of Wuhan strain, 9 d shorter than that of Bioforte strain, and the oviposition time of F′ strain was 1.4 d shorter than that of Wuhan strain. The eclosion time was 4 d shorter than that of Bioforte strain, and the oviposition time was 5.4 d shorter than that of Bioforte strain. In terms of feed utilization, the apparent digestibility of F strain, F′ strain, Wuhan strain and Bioforte strain were 59.53%, 59.25%, 58.05% and 58.10%, ingested feed conversion efficiency were 4.11%, 4.58%, 3.41% and 3.74%, and the feed-weight-ratio were 8.58, 7.78, 10.5 and 9.05, respectively. Compared with Wuhan strain and Bioforte strain, the apparent digestibility of F strain was significantly higher, and the eclosion time and oviposition time were significantly lower. The digested feed conversion efficiency, apparent digestibility and ingested feed conversion efficiency of F′ strain were significantly higher than those of Wuhan strain and Bioforte strain, while the feed-weight-ratio and protein content were significantly lower than those of Wuhan strain and Bioforte strain. There were no significant differences in the number of egg laid, quality of egg mass, or hatching rate between F strain, F′ strain and the Wuhan strain and Bioforte strain.【Conclusion】 F strain and F′ strain were superior to Wuhan strain and Bioforte strain in feed utilization, but the protein content was slightly lower than Wuhan strain and Bioforte strain; The number of egg laid, quality of egg mass and hatching rate of F strain,F′ strain were well maintained at the level of Wuhan strain and Bioforte strain; F strain had an advantage in growth cycle, and its eclosion time and oviposition time were shorter than Wuhan strain and Bioforte strain. |
