Greenhouse experiments were carried out to control the greenhouse whitefly (Trialeurodes vaporariorum WESTWOOD) on tomatoes by the combined use of yellow sticky traps with the parasite Encarsia formosa GAHAN.In the treatments where the parasites were introduced after monitoring by yellow sticky traps, the results were successful. Whitefly infestations were maintained at low levels throughout the season. In the treatment where many yellow sticky traps were used to control whiteflies by mass trapping with the parasite, the results was also successful. However, the combined effectof the parasite and the mass trapping was not significantly evident. From the practical point of view, use of yellow sticky traps was thought to be more promising for monitoring than for mass trapping.
