不同柞树品种对柞蚕的饲喂效果

Study on the Feeding Effects of Different Varieties of Oak Leaves on Tussah

[目的]为传统养蚕业提供理论依据。[方法]以河南省主要柞树品种为试验材料,研究不同柞树品种对柞蚕的饲喂效果。[结果]饲喂槲栎的柞蚕发病率比栓皮栎和麻栎高。饲喂栓皮栎和麻栎的柞蚕茧层率都比槲栎高。全龄用栓皮栎和麻栎养蚕的效果最好,用槲栎养蚕的效果最差。[结论]栓皮栎和麻栎是适宜鲁山县区气候和环境条件,是柞蚕喜食、养蚕效果较好的优良柞树品种。

[Objective] The research aimed to provide theoretical basis for traditional sericulture. [Method]Taking main varieties of oak tree in Henan Province as test materials,the feeding effects of different varieties of oak tree on tussah were studied. [Result] The incidence of tussah fed with Quercus aliena was higher than that fed with Quercus variabilis and Quercus acutissima. The cocoon shell rate of tussah fed with Q. variabilis and Q. acutissima was higher than that fed with Q. aliena. The feeding effects of tussah fed with Q. variabilis and Q. acutissima in all instars was the best,and that fed with Q. aliena was the worst. [Conclusion] Q. variabilis and Q. acutissima were suitable for the local climate and environmental conditions in Lushan County,and they were good varieties of oak trees that tussah liked to eat with better feeding effects.
