Greenhouse Whitefly

Greenhouse Whitefly (Trialeurodes vaporarium) produce a sugary substance known as honeydew, which may favour the development of sooty mould. The damage caused by whitefly is a consequence of the high rate of reproduction of the species and the short generation time. Low numbers of whiteflies do not cause significant damage to the host plant. Although whitefly adults do not always cause significant damage by themselves, they are a vector for viruses and can spread damaging diseases through crops. When whiteflies are present in large numbers, their feeding affects plants by causing poor growth, stunting, defoliation, reduction of yields, distortion and discoloration
