蔗飞虱是为害甘蔗的害虫之一。过去,在我站很少发现,为害不严重,而没有引起人们的注意。1972年我站发现约2亩蔗田有蔗飞虱,1973年已蔓延至5亩多,今年6月底检查,已有10亩的甘蔗受到了为害。我们在台山、海康、番禺、陆丰等地亦发现有为害甘蔗,而且有些比较严重。初步看来,蔗飞虱繁 Planthopper is one of the pests that damage sugarcane. In the past, I rarely found in the station, the damage is not serious, but did not attract people’s attention. In 1972, we found about 2 acres of sugarcane plantain had planthopper in our station. In 1973, it spread to more than 5 mu. Checked by the end of June this year, 10 mu of sugarcane was harmed. We also found harmful sugarcane in Taishan, Hikvision, Panyu, Lufeng, etc., and some of them are more serious. Preliminary view, sugarcane planthopper
