A screening of plant protection products for their effectiveness against the greenhouse whitefly (Trialeurodes vaporariorum Westw.) was made in growing of  tomatoes in greenhouses. The experiments were conducted during the period 2009-2014 in unheated greenhouses in the „Maritsa” Vegetable Crops Research Institute, Plovdiv. It was found that the products Confidor Energy OD 0,08%, Actara 25 WG 0,03%, Mospilan 20 SP 0,02% and Eforia 45 CS 125 ml/da have very good effectiveness against adults and larvae of the greenhouse whitefly. Phytopesticide Piros 0,08% has good effectiveness against adults and satisfactory against the greenhouse whitefly larvae. This product could be used as an alternative to control this pest in integrated and organic production of tomatoes in greenhouses.
