Fig Whitefly  Prior to introduction to Florida, the fig whitefly was known only from China, Burma and India.  Little literature exists on the biology of this insect but it is noted as a minor pest of Ficus species in India.  The only natural enemy listed in literature was the parasitic wasp Encarsia tricolor (Hymenoptera: Aphelenidae)
