The tobacco whitefly (Bemisia tabaci) belongs to the family Aleyrodidae, and the sub-family Aleyrodinae. This insect was first identified on tobacco in Greece in 1889, hence the name tabaci. It has subsequently been found in most tropical and subtropical countries of the world. The original habitat was probably a tropical or subtropical area, possibly Pakistan.
The tobacco whitefly (Bemisia tabaci) has an enormous host range and has affected an extremely wide range of crops throughout the world. It causes damage in (sub-)tropical areas especially. The tobacco whitefly (Bemisia tabaci) is feared because of its high level of resistance to many insecticides and its propensity for the transmission of viruses.
