Different baits insecticides commercialized and others artisanly produced with sesame, Sesamum indicum, were evaluated in the control of lemon leaf cutter anthills, Atta sexdens rubropilosa Forel, 1908. The experiment was held in one tem years old Eucalyptus camaldulensis plantation and two of sprout. It was tested ten treatments, including the standard, with the following active ingredients: chlorpyrifos, sulfluramid, fipronil, flour of sesame leaves (15%), flour of sesame seeds (10%, 20% and 30%). The mortality verification of the anthills was held at the 30, 60, 90 and 150 days after the treatment. The most efficient baits were sulfluramid and fipronil, followed by the formulation of flour of sesame leaves (15%). The baits of sulfluramid and of fipronil reached the maximum control in the evaluation of the 30th day, whereas the baits of sesame leaves (15%) presented satisfactory control starting from the third evaluation at the 90th day. The results obtained with the bait of sesame leaves (15%) were promising encouraging new studies to be held.
