Larvae ‣ Newly hatched larvae crawl quickly to spread out or spin silk to move to other plants; ‣ Prefer sugar and moisture, but don’t like light; 3. Behavior
3. Behavior Larvae ‣During the late seedling period, newly hatched larvae feed on the mesophyll of young un-spread leaves or bore into curled young leaves to produce consecutive spots or holes when the leaves are unfurled. The situation of consecutive holes, caused by the insects boring through un-spread leaves’ layers is often called “ 花叶或链珠孔 ”. 在玉米心叶期 , 初孵幼虫取食未展开的心叶叶肉 , 或将纵卷的心叶蛀穿 , 到心叶伸展后 , 叶面呈现半透明斑点 , 孔洞呈横列排孔 , 通称 “ 花叶或链珠孔 ”。
