湛江蔗区是本省的糖业新基地。1965年植蔗面积约佔全省的33％。湛江高旱地蔗区的自然特点是土地瘦瘠,水源缺乏、虫害严重、台风威胁大,加上历来栽培管理粗放,因而,甘蔗产量低而不稳。在虫害中,以甘蔗螟虫为主,为害普遍而严重,对甘蔗生产威胁很大,造成苗期枯心率一般10-30％,严重的达50％以上,苗期为害以二点螟为主(佔80-90％),到生长中后期则以白螟和黄螟为主。

Zhanjiang sugarcane area is the province’s sugar new base. In 1965, the area of ​​sugarcane accounted for about 33% of the province. The natural features of Zhanjiang high-dry sugar cane are land thin barren, lack of water, serious pests, large typhoon threat and extensive cultivation and management. Therefore, the output of sugarcane is low and unstable. Among the pests, sugarcane borers are the most common and harm is common and serious, which threaten the production of sugarcane, resulting in a dry matter rate of 10-30% at seedling stage and over 50% in severe stage. Accounting for 80-90%), to the late and late growing borer and yellow rice stem borer.
