Lettuce (Lactuca sativaL.) is among the vegetables of great importance in Brazilian food, being an excellent source of vitamins and minerals. However, their cultivation is impaired due to the adverse weather conditions, the presence of pathogens and the pests attack. The objective of this work was to evaluate the reaction of four lettuce varieties to the leafminer. The insect attack reaction was verified by the evaluation of the percentage of infested plants twenty days after sowing. The data were submitted to ANOVA and submitted to the Duncan test (P<0.05). The results showed a differentiated reaction between the lettuce varieties to the attack of the leafmine, with the variety Roxa presenting high resistance and Americanavariety demonstrating high susceptibility to the infestation of Liriomyzaspp.
