Perdas de peso no processo de beneficiamento do café em consequencia do ataque da broca do café Hypothenemus hampei (Ferrari, 1867)(Coleoptera-Scolytidae)

The coffee (Coffea arabica L.) borer (Hypothenemus hampei) is and important pest of coffee in Brazil, being of particular importance because of direct and indirect damages to coffee beans. The objective of the present work was to correlate different percentages of infestation of berries in the field with weight losses caused during processing by the mechanical effect of the machines on damaged beans. Samples from the two main producing regions in Minas Gerais State, Sul de Minas and Zona da Mata were taken. The coffee berries were carefully collected and hand selected to garantee that changes in weight were caused only by the coffee borer. The berries from each of the regions considered were separated in two groups: one of them containing only healthy berries, and the other with damaged ones. Both groups were put to dry separately on the ground, at fall sun, as it is done traditionally by the maiority of the growers. Treatments were prepared afterwards simulating infestation levels of 0, 1, 3, 5, 7, 10, 20, 40, 50, 80 and 100 percent; each treatment was repeated three times. The losses during processing were up to 2,43 percent and 4,23 percent by weight, for beans from Sul de Minas and Zona da Mata regions, respectively
