二疣犀岬(Orycles rhinoceros)是马来半岛幼龄油棕和椰子的常见害虫。成虫通过钻蛀幼叶基部,取食多汁的枪叶和嫩叶组织。如果生长点受到损害,幼树就会死亡。定植大田后头两年是最危险的时期,此后由于油棕冠层郁闭而形成自己的植物生长屏障,犀(虫甲)的为害逐渐减少。成龄油棕树实际上没有受害。 Orycles rhinoceros is a common pest of young palm oil and coconut in Malaya. Adults pass through the base of young leaves and feed juicy leaves and young leaves. If the growing point is damaged, saplings will die. The first two years after the colonization of the field were the most dangerous periods, after which the plant growth barrier was formed as the canopy of oil palm closed and the damage of the rhinoceros (insects) gradually decreased. Aging oil palm is virtually unharmed.
