甘蔗的一生均受到蔗螟的为害。幼期受害造成枯心苗,伸长期拔节后受害造成螟害节或枯梢(死尾蔗),结果有效茎数减少,蔗株不高,糖分降低,对甘蔗的产量和质量均有严重的损失。是影响甘蔗产量的主要因素之一,及时防治蔗螟为害是确保甘蔗高产优质的一项重要措施,不能忽视。蔗螟种类多,有黄螟、条螟、二点螟、白螟、大螟及台湾稻螟等多种。发生期复杂,为 Sugarcane’s life are affected by sugarcane borer. Suffering from infancy resulted in dead-heart seedlings. After elongation, the damage caused stem borers or dead shoots (dead tail cane) caused by the injury after elongation. As a result, the number of effective stalks decreased, the cotyledons were not high and the sugar content was low, and the yield and quality of sugarcane were both serious loss. Is one of the main factors affecting the yield of sugarcane. It is an important measure to ensure the high yield and quality of sugarcane in time to prevent the damage of the sugarcane borer and can not be neglected. There are many kinds of sugarcane borer, including Sesamia inferens, Borer borer, Borer borer, Sesamia inferens, Sesamia inferens and Taiwan borer. Complex occurrence of
