摘要
花尾榛鸡是我国重要的经济鸟类,体内富含15种氨基酸,具有很高的营养价值.近10年来,我国北方的许多部门进行了其人工饲养繁殖的研究,但种群数量始终达不到理想的指标.影响种群数量增长的主要因素是雏鸡的成活率低,影响雏鸡成活率的主要因素是雏鸡的食物即营养问题.其次还有疾病、饲养管理水平、种鸡的质量等因素也不同程度的影响其种群数量的增长.
This paper reports a new genus and species of grasshopper from Liaoning Province.The type is deposited in the School of life science, Northeast Normal University. Chrysochraoides gen.nov.
