ABSTRACT: Tomato is one of the main crops affected by the damage of Bemisia tabaci (Hemipetra: Aleyrodide), causing damage and disease. This pest is responsible for large losses in this crop and also in greenhouse. Whiteflies are pests of various crops that cause reduction in fruit yield and quality. Thus, the objective of this work was to know the influence of the whitefly Bemisia tabaci (Gennadius) on the resistance of two tomato varieties (Santa clara and carolina) in two environments. The work was conducted in a greenhouse at the State University of. Alagoas - UNEAL, Campus I in the city of Arapiraca AL. The research period was from August 2017 to July 2018. The experiment was set up in two tomato varieties, Carolina and Santa clara distributed in 5 kg pots. The experimental design was completely randomized with ten replications. More heterogeneous and more dispersed values ​​were obtained in relation to the number of nymphs in the two varieties, in Carolina standard density (16.83 ± 11.90), in Santa variety clear standard density (97.84 ± 69.19). Thus, it can be concluded that the Carolina variety showed greater resistance to the population dynamics of whiteflies in vegetative and reproductive development represented by the data found.
