Résumé : This work was addressed to study the effects of landscape on the short distance dispersal (?140 m) of coffee berry borer (CBB). We conducted a six-month study during the flight period of the CBB (January to July 2009), in six locations of the Turrialba region, in Costa Rica. We measured CBB movement in transects spanning isolated coffee plantations into three adjacent land uses: forest, sugar cane and pasture. At each location, we placed six transects starting 30 m within the coffee plantation, continuing 140 m into each of the adjacent land uses. Within these transects we placed one CBB trap (Brocap®) each 10 m. Despite a low frequency of dispersal events outside of coffee, we found significant differences in the permeability of the three adjacent land uses. The forest generated the greatest friction to CBB movement: the number of CBB captured in forests was only 12 % and 19 % of the number of CBB captured in sugar cane and pasture respectively. This finding suggests that breaking connectivity between coffee plantations may help to reduce CBB dispersal particularly when low permeability land uses such as forests are placed between coffee plots.
