Agrotis ipsilon cut the little plant after the transplant and cause low stand and produtivity. One experiment with randomized blocks and four replicates was installed to study the insecticide effect for the larval insect fase. The plot, 48 trees were conducted with six files, and 1,15 x 0,45 m between lines and tress, respectively. The treatments were constituted by following commercial insecticides (grams): 1) Confidor??S (420) (imidacloprid 50% + cyfluthrin 1%); 2) Confidor??S (500); 3) Confidor 700 GRDA (300) (imidacloprid 70%); 4) Orthene 750 BR (750) (acephate 75%); 5) Confidor??S (320); 6) Confidor??S (360); 7) Confidor??S (400); 8) Confidor??S (420); 9) Confidor??S (500); 10) Confidor??S (300) + Orthene 750 BR (600); and 11) control. Treatments one to three each trees was aspersioned with 14 ml of solution at the time of transplanting. Treatment four the trees were sprayed at the time of transplanting, 15 and 30 days after with 8,3 ml solution for time and tree. With the treatments five to ten, the trees were washed yet in the trays with 2 ml solution for little plant. After installment of the experiment were liberated eight caterpilars for plot that were previously collected for this finality. The evaluations were three, seven, 13 and 27 days after counting trees cut. Results showed that the treatments with Confidor??S (360, 420 and 500 g) applied in the trays, and Confidor??S (500 g) applied at the time of transplanting, and Confidor 700 GRDA (300 g) + Orthene 750 BR (600 g) applied at the trays had control across Abbott Test by 84,2%, 89,4%, 100,0%, 89,4% and 94,7%, respectively, in the evaluation 27 days after to install the experiment. Results showed also that the same inseticide dose were more efficients when applied in the trays.  aControl  aLagarta rosca  aNicotiana tabacum  tIn: INTERNATIONAL CONGRESS OF ENTOMOLOGY, 21., 2000, Foz do Igua??u, PR.
