摘　　要：从柑橘粉虱(Dialeurodes citri Ashmead)越冬若虫量以及嫩叶上的卵量、若虫量3个方面对我国主栽的7类14个柑橘品种做了田间调查,结果显示,柑橘粉虱对这14个品种的寄主选择性存在明显的差异。就嫩叶卵量和若虫量来看,南丰蜜橘是其中对柑橘粉虱吸引力最强的品种,就这3个指标来说,HB柚均为最抗柑橘粉虱的品种。The field population density of overwintering nymphs,nymphs and eggs of Dialeurodes citri on young leaves of 14 cultivars in 7 groups of citrus was investigated.The result showed that there was significant differences of D.citri among the selectivities to those cultivars.Nanfeng Orange was the most attractive cultivar;while HB pomelo was the least one.
