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
菠萝灰粉蚧Dysmicoccus brevipes（Cockerell）是我国菠萝凋萎病的主要传播媒介,防治该虫是控制菠萝凋萎病的有效途径。该虫在我国为孤雌生殖,遗传结构简单,根据COI序列差异可分为3个基因型,即南宁型、琼海型及万宁型（He et al.,2012...菠萝灰粉蚧Dysmicoccus brevipes（Cockerell）是我国菠萝凋萎病的主要传播媒介,防治该虫是控制菠萝凋萎病的有效途径。该虫在我国为孤雌生殖,遗传结构简单,根据COI序列差异可分为3个基因型,即南宁型、琼海型及万宁型（He et al.,2012）。随着菠萝种苗及果实的调运,不同基因型菠萝灰粉蚧在果园可能混合发生。为探索该虫不同基因型之间是否存在种群竞争,及这种竞争与其分布的关系,展开更多
