Resumo: 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.

O experimento foi realizado em 2008, em delineamento de blocos ao acaso, em parcelas subdivididas no tempo, com quatro repetições. Os tratamentos consistiram de quatro regimes de irrigação por gotejamento - balanço hídrico climatológico, irrigações com base nas tensões de 20 e 60 kPa, e uma testemunha não irrigada -, os quais foram distribuídos em três densidades de plantio: 2.500, 5.000 e 10.000 plantas por hectare. As avaliações foram realizadas mensalmente entre janeiro e dezembro de 2008. O maior período de ocorrência da praga foi registrado de agosto a novembro, época de baixa umidade relativa do ar antecedida por período de estiagem. Cafeeiros irrigados apresentaram incidência de minas intactas 2, 2 vezes menor do que as plantas não irrigadas. A irrigação e o aumento da densidade de plantio contribuem para a redução da incidência do bicho-mineiro do cafeeiro.Embrapa Secretaria de Pesquisa e Desenvolvimento Pesquisa Agropecuária Brasileira2019-11-14T17:05:04Z2019-11-14T17:05:04Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfASSIS, G.
