Widespread distribution. South and Central America, Africa, Caribbean, Oceania. On plants in potato, brassica and cucurbit families. An important pest of capsicum and kava.
Eggs laid in circles, nymphs are 'crawlers' at first then settle becoming oval, black, covered by curly strands of wax; adults, 2-3 mm, look like spiralling whiteflies. They produce 'honeydew' excretion.
Sucks plant sap; sooty moulds grow on honeydew.
Natural enemies: a minute wasp, Encarsia formosia, is widely used to control this whitefly.
Chemical control: soap, white or horticultural oils; note that most synthetic insecticides will kill natural enemies.
