High diversity of bees detected in guarana crop and natural habitat due to the use of combined sampling methods.

Bees are the main pollinators of native and agricultural plants. Identifying and knowing these insects responsible for the environmental service of pollination is essential for the maintenance and management of pollination in agricultural systems, especially in a high diversity biome as the Amazon rainforest. Some crops in this region are dependent of benefited by wild pollinators, especially native plants like guarana. To address methodological aspects of monitoring bee diversity, samplings were carried out in an agricultural environment (guarana crop, Paullinia cupana) surrounded by Amazon natural habitat at Manaus, Amazonas State.
