This study was conducted in a rubber tree/coffee plant interface that was influenced by the trees to a varying degrees depending on the location of the coffee plants, i.e. from beneath the rubber trees, extending through a range of distances from the edge of the tree plantation to end in a coffee monocrop field. The most severe damage inflicted on coffee plants by the CLM (number of mined leaves) from April, which marks the start of the water deficit period, until September 2003 was in the zone close to the rubber trees, whereas the damage inflicted on plants in the monocropped field was comparable to that on coffee plants grown directly beneath the rubber trees, which received about 25-40 % of the available irradiance (Ir-available irradiation at a certain position divided by the irradiation received in full sunlight, i.e. in the monocrop). From May until July damage caused by the CLM nearly doubled in each month. In midwinter (July), the damage decreased perceptibly from the tree edge toward the open field. From September onward, with the rising air temperatures CLM damage in the coffee monocrop started to increase. Based on these results, we conclude that coffee plants grown in the full sun incurred the most damage only at the end of winter, with warming air temperatures. Coffee plants grown in shadier locations (25-40 % Ir) were less damaged by the CLM, although a higher proportion of their leaves were mined. The rubber trees probably acted as a shelter during the cold autumn and winter seasons, leading to greater CLM damage over a distance outside the rubber tree plantation that was about equal to the height of the trees. Future studies should attempt to relate leaf hydric potential to pest attack in field conditions. More rigorous measurements of shade conditions could improve our understanding of the relationship of this factor to CLM attack.  aAgroforestry  aContinuous cropping  aLeafminers  aMixed cropping  aPlant pests  aShade agroforestry systems  aAgrossilvicultura  aBicho mineiro  aCafe  aCaucho  aCoffea arábica  aConsorciação de cultura  aCultivo Continuo  aHevea  aLeucoptera coffeella  aMonocultura  aPerformance  aPerileucoptera Coffeella  aPraga de planta  aSeringueira  aSombreamento  aAgroforestería  aCoffee  aCultivo mixto  aMinador de las hojas  aPlagas de plantas  aRubber tree  aSistema Agroflorestal (SAF)  aSistemas de sombra1 aCAMPOE, O.
