摘要: 角倍蚜人工繁殖技术的效益分析王健,傅小川关键词角倍蚜,五倍子,经济效益角倍是主要的五倍子种类之一,质量好、分布面积大,占五倍子总产量的75%.遵义是五倍子的最佳产区,历史上最高年产曾达到5000余t。自1982年以来,年产仅有500余t,且处于野生野长状态。为了改变角倍单产低,产量不稳定的状况,从研究角倍蚜Schlechtendalia chinensis(Bell)的人工繁殖入手,以增加单位面积的虫口密度,达到高产稳产的目的1~2 。Abstract: This paper deals with the rearing of horned gall aphid,Schlechtendalia chinensis. The analysis on the major technical and economic indices for rearing the aphid has demonstrated that this set of technique is promising.
