如何区别棉铃虫和烟夜蛾幼虫(烟青虫)是国内外农业生产上的一个重要问题,至今还未很好解决。我们利用扫描电镜初步解决了这个问题。借助于扫描电镜,我们发现棉铃虫和烟青虫在触角第三节末端感觉锥、气门、气门筛和表皮突起这四个方面存在比较明显的差异。
How to distinguish the cotton bollworm and the tobacco budworm larvae (tobacco budworm) is an important issue in agricultural production at home and abroad, has not yet been well resolved. We use scanning electron microscopy to solve this problem. With the help of SEM, we found that the cotton bollworm and tobacco budworm had more obvious differences in the four aspects of sensory cone, valve, valve sieve and epidermal protrusion in the third quarter of antennae.
