甘蔗红尾白螟(Tryporyza intacta F.)发生于广东、广西、台湾等省(区),是我国南方蔗区的主要害虫之一。甘蔗受害后由于全株枯死或梢头死尾以致生长停滞,茎重减轻,使每亩减产约10—20%。此外还引起蔗糖份下降0.57—1.76%(绝对值)。近年来广东雷州半岛此虫发生日趋严重,成为甘蔗生产上的主要问题之一。 Tryporyza intacta F. occurs in Guangdong, Guangxi, Taiwan and other provinces (regions) and is one of the major pests in sugarcane fields in southern China. After the sugarcane victimizes, the whole plant will die or the dead end of the plant will stop its growth and reduce the stem weight, which will reduce the yield by about 10-20% per mu. In addition it also caused a 0.57-1.76% drop in sucrose (absolute value). In recent years, the occurrence of this insect in Leizhou Peninsula of Guangdong Province has become more and more serious, becoming one of the main problems in the production of sugar cane.
