| 中文摘要: |
| 2011-2013年对突背蔗犀金龟在广西蔗区的发生区域和为害情况进行调查。结果表明，突背蔗犀金龟主要分布在百色地区（右江河谷一带）和河池地区（宜州市、罗城县）。其中，平果县果化镇的虫口密度最大，达22555.7头/667m2，宜州和田阳蔗区甘蔗苗期被害最重，枯心苗率分别为40.6%和35.4%，宿根蔗比新植蔗受害严重。 |
| 英文摘要: |
| Distribution and damage of Alissonotum impressicolle Arrow were investigated in Guangxi sugarcane planting areas from 2011 to 2013. The results showed that A. impressicolle was mainly distributed in Baise district (Youjiang river valley area) and Hechi district (Yizhou City and Luocheng County). Population density of A. impressicolle was the most (22 555.7 larvae per 667 m2) in Guohua Town, Pingguo County. In Yizhou and Tianyang areas，sugarcane was severely damaged by A. impressicolle at the seedling stage, with the dead heart rates of 40.6% and 35.4%, respectively. The ratoon cane was damaged more seriously than newly planted cane. |
