Bemesia argentifolii

Silverleaf Whitefly
Binomial:Bemesia argentifolii
Order: Hemiptera

The silverleaf whitefly (Bemisia argentifolii, formerly referred to as sweetpotato whitefly-strain B Bemisia tabaci) is one of several whiteflies that are currently important agricultural pests. The silverleaf whitefly was first found in poinsettia crops in Florida in the mid-1980's. It was found to have moved on to tomatoes and other fruit and vegetable crops less than a year later. Within five years, the silverleaf whitefly had caused over $100 million in damage to the Texas and California agriculture industries.

Description edit

The adult silverleaf whitefly is about 1 millimeter in length and pale yellow in color.

Symptoms and Signs edit

In addition to inflicting typical whitefly-type damage on plants, this species can transmit plant viruses such as geminiviruses. The broad mite (Polyphagotarsonemus latus) also uses the whitefly as a dispersal mechanism by clinging to the legs of the fly and dropping off at another plant.[1]

Ecology edit

Host plants edit

Control edit

This particular pest has been shown to be a good candidate for biological pest control, as it has several natural enemies, including parasitic wasps such as Encarsia and Eretmocerus.
