RESUMO

The aims of this study were: to investigate potencial pollinators of strawberry crops in commercial fields; to verify the contribution of several pollination agents on strawberry productivity, studying the floral and reproductive biology of some commercial cultivars; to evaluate the possibility of the rational use of stingless bees in strawberry pollination inside greenhouses. The results showed that the floral morphology of "Sweet Charlie" and Oso Grande" cultivars and the maturation pattern of their stamens and pistils nor favour the occurrence of self pollination neither the regular pollen distribuction among stigmata, yielding deformed fruits that don´t complete their development. Therefore these cultivars need pollinators to commercial production. Tetragonisca angustula (Apinae, Meliponini)was remarkable for its relatively quick adaptation inside greenhouses and for its effectivity as strawberry pollinator, resulting in heavier berries and high percentage of marketable fruits.
