Abstract

The woolly whitefly, Aleurothrixus floccosus (Maskell) (Hemiptera: Aleyrodidae), a potentially serious citrus pest, recorded from South Africa.

Abstract

A whitefly that has been noticed over the last two years on many lemon trees in suburban gardens of Cape Town and in Stellenbosch has been identified as the woolly whitefly, A. floccosus. This is thought to be the first record of this species from South Africa. Subsequently, it has been found all the way along the broad coastline from Stellenbosch to Port Elizabeth, and is apparently even more widespread in South Africa, as it was found on a lemon tree in a Pretoria garden in May 2009. The origin, spread, geographical distribution, feeding behaviour, biological development, fecundity, parasitoids, and control of A. floccosus are described. A photograph of a lemon leaf with A. floccosus and a black sooty mould fungus (Capnodium sp.) is provided.
