Resumo
O plantio de Coffea arabica é muito importante na região do Alto Paranaíba – MG, e a principal praga- chave na cultura do cafeeiro é Leucoptera coffeela. O controle mais utilizado é o químico, porém o uso excessivo destes produtos tem selecionado populações resistentes a inseticidas, além do uso de inseticida a migração de insetos resistente é outro fator importante no estudo de resistência. Para o estudo detalhado de resistência de insetos a aplicação de questionário é importante para relatar a quantidade de inseticida usado ao longo dos anos. Assim, o objetivo deste trabalho foi aplicar questionários em propriedades com diferentes níveis de produção a fim de utilizar esses resultados como base para estudo de resistência do bicho-mineiro-do-cafeeiro. Os inseticidas mais utilizados pelos produtores pertencem aos grupos dos organofosforado, avermectinas e clorociclodieno. E as aplicações destes são feitas com dosagens permitidas.

The control most widely used is the chemical, however overuse of these products has selected populations resistant to insecticides, beyond of insecticide use insect migration is another important factor in study of resistance. For a detailed study of insect resistance the application of questionnaire is important to report the amount of insecticide used over the years. So, the objective of this work was to conduct questionnaires in property with different levels of production in order to use these results as a basis for study of resistance to leaf miner of coffee. The insecticides most used by producers belong to the group of organophosphate, avermectin and clorociclodieno. And these applications are made with the allowed dosages.
