Micro-landscape context effects on the dispersal of coffee berry borer (Hypothenemus hampei) in Costa Rica
The coffee berry borer (CBB) #Hypothenemus hampei# (Ferr.) has been detected in the Costa Rican landscape since 2000 from whence it has rapidly expanded its territory, colonizing new coffee farms. Although the males of the species have atrophied wings and are flightless, females have the ability to fly, and particularly do so when seeking new coffee berries to colonize after harvest. Distances covered by CBB are known to be large enough to reach proximate pest free areas (Baker, 1984); however, the number of individuals able to fly great distances across non-coffee land uses is probably low. As a consequence, CBB dispersal is believed to be facilitated by the connectivity between coffee plantations, but may be hampered by fragmented landscapes when alternate land uses are found between coffee patches. The aim of this study was to understand the effect of landscape context on the short distance dispersal ( 140m) of CBB in the Turrialba canton. Turrialba is a low altitude coffee region of Costa Rica under Caribbean influence, favorable to CBB development.
