Abstract : The coffee berry borer (Hypothenemus hampei) is a major pest of coffee in Central America. Recent studies demonstrate landscape context impacts distribution and dispersal of this pest where probability of successful dispersal events is higher across some agricultural land uses such as sugar cane and pasture, but limited by others, in particular forest. This impact of land use composition has been tested at local (Olivas et al. 2011), and landscape scales (Avelino et al. 2012). In this study, we used a small mixed-use landscape (550 x 500 m; 27.5 ha) to further test the impact of land use composition and arrangement on coffee borer densities and distribution. We placed 121 ethanol-based coffee borer traps (Brocap ®) at 50 m intervals throughout the sample grid plus an additional 32 traps located 10 m from adjacent traps along both diagonals of the study area for a total of 153 traps. We checked these traps every two weeks during a five-month period between February 2nd and July 7th 2010. Traps were located in seven different landuses, including: coffee (22%), pastures (22%); sugar cane field (18%), banana orchard (16%); pine plantation (10%), forest (9%); and annual crops (3%). We captured a total of 9984 dispersing female beetles, with the peak capture during the last two weeks of February. The majority of the coffee borers were found in the coffee plots as expected (89%). Eleven percent were found outside of coffee. The presence of coffee borers was significantly different in the alternate land uses with the lowest densities found in the forest (3%). Our results demonstrate that management of local landscape context can contribute to (but not replace) the control and management of the coffee boring beetle by limiting the movement of the organism and either increasing the effectiveness of field scale management intervention and/or reducing re-infestation rates.
