Integrated control of Bemisia tabaci in vegetable crops

The silverleaf whitefly Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is one of the most significant agricultural pests worldwide, partly because it is a very efficient vector of numerous plant viruses. Bemisia tabaci is a species-biotype complex that has a wide range of hosts, high fertility and good adaptability to diverse environmental conditions. The biotypes present in vegetable crops in the Mediterranean region are some of the most invasive, and are highly resistant to some of the most commonly used insecticides. The vegetable crops most affected by B. tabaci are tomato, pepper and cucumber.
Cultural measures and biological control are the primary means of controlling B. tabaci. Cultural measures aim to prevent early colonisation of the crop by managing the environment and surrounding crops. Mesh netting over openings in greenhouses is one cultural measure that has been widely implemented in areas with many greenhouses. Biological control based on inoculation and conservation of polyphagous predators has proven to be the most effective control method. Because these predators feed on other pests in addition to whitefly, they can remain on the crop when populations of B. tabaci are low. The large-scale implementation of integrated pest management by means of biological control has brought about good pest population control and a dramatic reduction in the incidence of the viral diseases transmitted.
