Conteúdo: | The objective of this work was to evaluate the effect of different drip irrigation regimes and planting densities on the incidence of the leaf miner, Leucoptera coffeella, in arabica coffee plants for one year. The experiment was carried out in 2008, in a complete randomized block design, in a split?plot in time arrangement, with four replicates. The treatments consisted of four drip irrigation regimes ? soil water balance, irrigations at 20 and 60 kPa soil tensions, and a nonirrigated treatment ?, which were distributed at three plant densities: 2,500, 5,000, and 10,000 plants per hectare. The evaluations were made on a monthly basis between January and December 2008. The highest pest occurrence period was from August to November, a season with low?air relative humidity preceded by a drought period. Irrigated coffee plants showed an incidence of intact mines 2.2 times lower than that of nonirrigated plants. Irrigation and increasing of plant density contribute to the reduction of coffee leaf miner occurrence.
