二黑条豚叶甲为当地自然生物物种,经过长期的适应,选择了以豚草为取食对象,并对豚草有明显的控制作用。豚草枯死率在5.91%~100%之间,平均为22.67%,5级被害率为77.33%,单株平均种子数为0.75粒,对豚草的翌年种群数量有明显抑制作用。该虫有望解决南方区域的豚草危害。 Two black dolphin leafhopper is a local natural biological species, after a long period of adaptation, chose to ragweed as the feeding object, and ragweed has obvious control.
