Resumo

Field Trapping of the Tomato Worm, Scrobipa/puloides absoluta (Meyrick) (Lepidoptera:Gelechiidae) Using Virgin FemalesStudies were carried out on catches of Scrobipalpuloides absoluta (Tvleyrick) males using traps baited with virgin females as a source of natural sex pheromone.Six different traps heights, six distinct colors and seven traps desigu were evaluated.It was found that the height of trap placement had an influence on male capture, and that the optimum height varied according to the g -owth stage of the plant.The design of the trap also influenced the efficiency of capture.The modeis "PVC 200" and Pherocon 1CR were the most efficient for the capture ofmale S. absoluta.The data on trap colar suggested that dark colors provided higher catches than lighter colored traps.
