The results indicated that both the two species of wasps could parasitize all nymphal stages of B. tabaci.

两种寄生蜂均可寄生烟粉虱的1~4龄若虫。

Antennae of B. tabaci are made up of scapus, pedicle and flagella that the latter consist of 1-5 segments and most of the antennal sensilla lie on its outer, upper and lower surfaces.

扫描电镜观察结果表明，烟粉虱触角由柄节、梗节和1～5节鞭节组成，绝大部分触角感受器分布在触角的背面、腹面和外侧面。
