Diversity and foraging patterns of bees on flowers of Cucurbita pepo (Cucurbitaceae) in Costa Rica

Introduction. The species and functional diversity of pollinators are important components for the reproduction cultivated plants. More information is necessary about this its geographical variation in crops such as Cucurbita pepo, one most global agriculture. Objective. To describe geographic community bees that visit C. pepo Costa Rica their foraging s
 Introduction: an crop Objective: taxonomic diversity, patterns Rica. Methods: Squash fields were visited at 11 locations within three regions country, where groups relative frequency determined. Through video recordings, was obtained on behavior two locations. Results: A minimum 27 belonging to 19 genera 2 families found. Three dominant 10 localities (Eucera limitaris, Apis mellifera Trigona corvina). Altitude reduces bee due dominance Bombus ephipiatus high regions. Two halictids (Megalopta Caenaugochlora) rarely reported frequently observed. dominated among flowers later morning, lacerating nectary holes facilitate nectar collection. Conclusions: by a highly diverse community, which may ensure pollination via complementarity face spatial or seasonal changes environmental conditions.
