Tobacco Whitefly (Bemisia tabaci)
Highly invasive whitefly species capable of virus transmission and resistant to many pesticides.
Tobacco whitefly (Bemisia tabaci) is an invasive and economically important pest of protected crops worldwide. It feeds on many hosts including tomatoes, cucumbers, peppers, salads and ornamentals. Damage includes honeydew, sooty mould, leaf yellowing and virus transmission. Biocontrol relies on parasitoids such as Encarsia formosa, Eretmocerus eremicus, predatory mites like Amblyseius swirskii, and generalist predators such as Macrolophus pygmaeus. Early preventative releases are essential to prevent population buildup.
