摘要
烟粉虱在13种园林植物和1种蔬菜上被发现。烟粉虱的形态变异与寄主叶片的结构相关。在有毛的叶片上,若虫和蛹通常体型较小,虫体背面具有大刚毛,边缘凹陷,有时深凹。在无毛的叶片上,体型较大,虫体背面具有微小刚毛,很少有大刚毛,其边缘光滑。
Bemisia tabact (Gennadius) has been found on thirteen species of ornamental plants and one species of vegetables. The morphological variations of B. tabaci are correlated with the structure of the host leaf. On hairy leaves, nymphs and pupae are often small with elongated dorsal setae, their margins are crenelated and sometimes indented deeply. On glabrous leaves, they are large with microselae or least elongated dorsal setae, their margins are smooth.
