The coffee leaf-miner (CLM) (Leucoptera coffeella Guérin-Mèneville; Lepidoptera: Lyonetiidae), the main pest of coffee plants, occurs widely throughout the Neotropics where it has a significant, negative economic and quantitative impact on coffee production. 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.

No ano agrícola de 1997 foram avaliadas vinte e uma cultivares de milho, em vinte e nove locais do Nordeste brasileiro, em blocos ao acaso, com três repetições, objetivando oferecer mais alternativas aos agricultores da região, na seleção de materiais superiores para os diferentes sistemas de produção prevalescentes em todo o nordeste. As análises de variância conjuntas mostraram diferenças entre as cultivares, os locais ecomportamento inconsistente das cultivares frente às variações ambientais para as características altura de plantas e de espigas, estande de colheita, número de espigas colhidas e rendimentos de grãos. Os híbridos mostraram melhor adaptação que as variedades e populações, destacando-se as BR 3123, Agromen 2003 e Agromen 2010, com melhores desempenhos, apesar de não diferirem de alguns outros, estatisticamente. As variedades BR 106, BR 5011 e BR 5033 mostraram boas produtividades, justificando as suas recomendações para exploração comercial. As variedades precoces, BR 5033, BR 5028, BR 473 e BR 5037 constituem-se em alternativas importantes para as regiões mais secas do Nordeste brasileiro. |
