摘要
扫描电镜观察发现,麦红吸浆虫幼虫头部有一对橄榄形触角,胸部膜状,腹部背面有鳞片状突起,气门发达。幼虫身体表面分布有锥形感器,刺形感器和栓锥感器,从外部结构来看,这些感器主要属于温湿度感觉器。
A scanning electron microscope observation on the larvae of the wheat mige shows that there are olive-formed antennae, the thorax is membranous, there are stale-like projections on the back of abdomen, and the spiracules are well developed、On the surface of the body, there are basiconical, cheatical and styloconical sensilla. The outer structure suggests that they are thermoand hydroreceptors. This accounts for the reason that the larvae are sensitive to the changes of soil temperature and humitity.
