Survey on pests of longan (Dimocarpus longgana Lour. ) in Zhangjiang of Guangdong Province in 2011 found that F. virgata had caused serious damage on production of longan. The paper first reported damage status of F. virgata on longan and also preliminarily introduced field identification characterlstics and host plants of F. virgata reported.展开更多
