Resumo: | The aim of this work was to evaluate the influence of drip irrigation management on the incidence of the coffee leaf miner (CLM), Leucoptera coffeella (Guérin-Menéville 1842) (Lepidoptera: Lyonetiidae) during two years. The experimental design was randomized blocks with four replications and five irrigation managements, determined according to the seasons and availability of water in the soil. The evaluation was conducted by the CLM non-destructive method, collecting at random 10 branches of the middle third apex per plant in eight plants per plot, five branches on each side of the plant exposure to the sun. Thus, we sampled 160 leaves per plot, 80 on each face exposure of the plant. We observed the interaction between irrigation management and face exposure of the plant and single influence of the evaluation periods factor. In the treatment without irrigation and the management that is irrigated throughout the year whenever the content of available soil water reaches 25% of the total availability of water in the layer of 0-40 cm one observed, lower incidence of LM to face exposure of plants facing south. There was also a higher incidence of the insect pest at the lowest rainfall period between the months of April and October, but at low population level, less than 5%. |
