Greenhouse whitefly attacks many vegetable crops and ornamental plants.
Scientific name: Trialeurodes vaporariorum
Damage
Greenhouse whitefly sucks sap from tender vegetation to feed on. In the older leaves we find the last-stage nymphs. Its nymphs cause discoloration and necrosis while its sticky secretions stain the produce and degrade its value.
Enemy
The adult has a yellow body and its wings are covered with a white waxy coating. Its eggs are yellow at the beginning and it places them in a circle. When they approach maturity they darken and become shiny. The young nymphs are mobile and have a yellow glowing color.
At the next stages, settle down and feed by sucking off sap. These are oval in shape and yellow in color.
During the last stage (pupa) before the adult, do not feed. Peripherally it bears fringes (distinguished from Bemisia tabaci).
The red eyes and yellow body of the adult can be seen below the surface of its body. When the adults finally emerge, at first their wings are wet and sticky and they cannot fly. The adult flies to move usually only from plant to plant, although they have the potential for longer flight. It develops several overlapping generations.
Treatment
Careful control within the greenhouse is required so that the population can be dealt with when it is still starting to grow.
