Family Aleyrodidae

whiteflies

Tiny flies with large wings, white powder covering body and wings, these rarely affect plants seriously unless present in large numbers; if sooty mould fungus is also noted, they're probably too numerous

Insecticidal soaps or oils and yellow sticky traps may be helpful. The parasitic wasp Encarsia formosa is commercially distributed as pupae which are placed in infested areas, three or more times, until four-fifths of whitefly pupae have turned black. These may be used in conjunction with soaps and yellow tape, as the wasp is little affected by either. Pyrethrins may be helpful.
