  • Bemisia tabaci has long been considered a complex species. It rose to global prominence in the 1980s owing to the global invasion by the commonly named B biotype. Since then, the concomitant eruption of a group of plant viruses known as begomoviruses has created considerable management problems in many countries.
  • B. tabaci is a complex of 11 well-defined high-level groups containing at least 24 morphologically indistinguishable species. Bemisia tabaci (Gennadius) (Insecta: Hemiptera: Homoptera: Sternorrhyncha: Aleyrodoidea: Aleyrodidae: Aleyrodinae) is a phloem-feeding insect that lives predominantly on herbaceous species.
  • It is a considerable pest of ornamental, vegetable, grain legume, and cotton production, causing damage directly through feeding and indirectly through the transmission of plant pathogenic viruses, primarily begomoviruses. It has a global distribution. [1] [2].
