%X The aim of this work was to sample and learn about the populational dynamics of insect pests present in the industrial tomato in northern Minas Gerais, in the municipality of Itacarambi. Ten random points were sampled and four plants in each section, weekly, based on the standard procedure suggested for the tomato plant IPM (Integrated Pest Management). Viruses transmitters (aphids, whiteflies, and thrips) and leaf miners (tomato pinworm and leafminer fly) were evaluated. Whiteflies occurrence throughout the collection period was observed. In the first fortnight of the culture cycle, there was a higher thrips population. There was a populational peak of leafhoppers (Empoasca sp) at the cycle beginning, and a populational peak of thrips in the second fortnight of the culture cycle. Other key pests for the tomato crop as aphids and mites were not observed in the samples. Informations of this study allow directing control tactics for the periods in which the insect pests populations are higher. Keywords: Solanum lycopersicum, integrated pest management, whitefly. Objetivou-se, com este trabalho, amostrar e reconhecer a dinamica populacional de insetos-praga presentes em tomate industrial na regi o Norte Mineira, no munic¨ªpio de Itacarambi. Amostraram-se semanalmente dez pontos aleat¨®rios e, em cada ponto quatro plantas, semanalmente; com base no procedimento padr o sugerido para o MIP tomateiro. Foram avaliados: transmissores de viroses: pulg es, mosca branca e tripes; minadores de folha: tra a-do-tomateiro e mosca minadora. Observou-se a ocorr¨ºncia de mosca branca durante todo o per¨ªodo de coleta. Na primeira quinzena do ciclo da cultura houve maior popula  o de tripes. Observou-se a presen a populacional de Cigarrinha (Empoasca sp) no in¨ªcio do ciclo da cultura; e  aumento populacional de Tripes na segunda quinzena da cultura. Outras pragas-chave para a cultura do tomateiro como pulg es e tra as n o foram observados nas coletas. As informa  es deste trabalho permitem direcionar as t¨¢ticas de controle para os per¨ªodos em que as popula  es dos insetos-praga s o mais elevadas. Palavras-chave: Solanum lycopersicum, manejo integrado de pragas, mosca branca.
