黄褐色蔗龟(即齿缘鳃金龟或大等鳃金龟)(Exolontha serrulata(Gyllenhal))属鳃角金龟科,等鳃金龟属,是广东蔗区的主要金龟子种类之一。该虫过去在广东认为2年一代,而黄盈(1986)报道在漳州地区是1年一代,但黄成裕(1984)报道在福建晋江地区是2年一代。因此该虫的生活史仍未清楚。我们经过1984—1985两年在珠江甘蔗试验场的观察研究,表明黄褐色蔗龟在
Exotain (Gyllenhal) is one of the main chafer species in Guangdong sugarcane area. The insect used to be considered as a 2-generation generation in Guangdong, while Huang Ying (1986) reported a 1-generation generation in Zhangzhou, but Huang Chengyu (1984) reported that it was a 2-generation generation in Jinjiang, Fujian. Therefore, the life history of the pest is still not clear. After our 1984-1985 two years in the Pearl River Sugar Cane Experimental Observatory study showed that yellow brown sugar cane in
