Bee assemblage in habitats associated with Brassica napus L.

摘要: Assessments in agricultural crops indicate that alterations the landscape adjacent to can result reduced productivity due loss or low abundance of pollinating agents. In canola crop, production is partially dependent on insect pollination. Therefore, knowledge faunal diversity within and near crop fields key for management these insects consequently increase productivity. This study aimed determine compare bees habitats associated with southern Brazil. Bees were captured four areas using pan traps three habitat classes: (1) flowering (2) forest remnant, (3) grassland vegetation. The highest was observed vegetation (50%) field (47%). Eight species common classes recorded, which are represented by native social bees. addition, a single few individuals exclusive specific class; eight collected exclusively interior field, 51 vegetation, six remnant. majority rare recorded exhibits subsocial solitary behaviour inhabit open places. composition bee groups differed between showing importance maintaining mosaics friendly pollinators, promote pollination service flowers.
