Abstract:
... Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) is a worldwide pest that damages over 900 host plant species. The volatile organic compounds (volatiles) of contrasting plants, as well as their growth stage, influence this pest’s infestation behavior. The chemical contents of volatiles isolated from three plants (Gossypium hirsutum, Abutilon theophrasti, and Ricinus communis) during various growt ...

Abstract:
... The tobacco whitefly, Bemisia tabaci, is a fast-evolving complex species consisting of more than 35 cryptic species (biotypes). Among these species, the Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) are the most widely distributed and often cooccurrent. Field investigations showed that MED has eventually replaced MEAM1in most areas in China, but MEAM1still exists alone or together with ...
