Determination of losses caused by the greenhouse whitefly (Trialeurodes vaporariorum) in greenhouse tomatoes The greenhouse whitefly damages tomatoes by affecting growth, spreading disease and favouring the growth of sooty mold. We aimed to determine the losses caused by Trialeurodes vaporariorum on the total and commercial yields of greenhouse tomatoes. The study was carried out in crops at CECIF-FCA- UNL, which were transplanted on the 18/9/2002 and 5/8/2004 at a density of  2.4 plants.m -2. The treatments were: a) free culture T. vaporariorum from the start of flowering to harvest b) from the start of fruiting to harvest and c) throughout the cycle, using imidacloprid at a dose of 52 g ai.ha-1. Before each application adults and nymphs of T. vaporariorum were monitored and at harvest the total and commercial yields were determined. The total yield did not vary much, whereas the greatest commercial yield took place throughout the cycle.
