Summary:The tomato leafminer (Tuta absoluta) represents a serious problem for the tomato crop, not only due to the intensity of its attack, but also to its occurrence during all the crop cycle. In Brazil, this pest has been controlled almost exclusively with insecticides, what is undesirable for economic and environmental reasons. In order to get more information on the control of this pest this research was carried out, in Ouro Verde (Goias State, Brazil), from September through October 2002, to evaluate the use of light traps for capture of adult T. absoluta specimens. The treatments used were: 1) black lamp; 2) BLB lamp; 3) Grolux lamp; and 4) fluorescent daylight lamp. The experimental design used was randomized complete blocks with four replications. The parameter to evaluate treatment capture efficiency was the counting of the adult T. absoluta specimens trapped. The results showed mat the BLB and ultraviolet lamps were the most efficient treatments. Therefore, both can help to control the tomato leafrniner in integrated pest management programs.Original Abstract: A traca-do-tomateiro(Tuta absoluta) representa um serio problema a tomaticultura, nao somente pela intensidade de ataque, mas tambem por sua ocorrencia durante todo o ciclo da cultura. No Brasil, esta praga tern sido controlada, quase exclusivamente, com inseticidas, o que e indesejavel, tanto por motivos economicos, quanto ambientais. Visando a obter maiores informacoes para o controle desta praga, foi conduzido o presente trabalho, em Ouro Verde (GO), no periodo de setembro a outubro de 2002, com o intuito de avaliar o emprego de armadilhas luminosas na captura de especimes adultos desta praga. Os tratamentos utilizados foram: 1) lampada negra; 2) lampada BLB; 3) lampada Grolux; e 4) lampada luz do dia. O delineamento experimental utilizado foi blocos ao acaso, com quatro repeticoes. O parametro utilizado para avaliar a eficiencia de captura dos tratamentos foi a contagem do numero de especimes adultos de T. absoluta, capturados nas armadilhas luminosas. Os resultados demonstraram que as lampadas BLB e negra foram as mais eficientes na captura, podendo, portanto, ser empregadas para auxiliar no controle da traca-do-tomateiro em programas de manejo integrado de pragas.
