Sweetpotato whitefly (284) Print Fact Sheet


Common Name

Sweetpotato whitefly, tobacco whitefly, silverleaf whitefly

Scientific Name

Bemisia tabaci. There are a number of closely related strains (or biotypes) that appear the same as the local strains, but can only be identified by molecular techniques. The two most important are the silverleaf, MEAM1 or B biotype, and the Q or Mediterranean (MED) biotype. The B biotype is also referred to as a different species, Bemisia argentifolii, and more species may be named in the future from within this group. Both spread many viruses, and are resistant to many insecticides.
