Abstract

CARRIZO, E. del V. et al. Species of bee flora interest in Ojo de Agua Department, Santiago del Estero, Argentina. Quebracho (Santiago del Estero) [online]. 2015, vol.23, n.2, pp.100-101. ISSN 0328-0543.

The objective of this paper was to survey the plant species in Ojo de Agua Department, Santiago del Estero, Argentina, which are a source of nectar and pollen and are available to honeybee colonies. Floristic inventories were conducted in different areas of the Department between 2012 and 2013, and the presence of plant species which are known to contribute to the nourishment of honeybees were recorded. The presence of foraging bees on flowering species and the type of reward obtained (nectar or pollen) was detected by direct observation. Plant material was collected for identification through standard procedures. Seventy-six species, distributed in 26 botanical families, were identified as a source of nectar and pollen. The species are mostly native, with a predominance of shrubs (50 %), and are known to be major nectar providers (98 %). The botanical families most visited by bees were Fabaceae, Cactceae, Asteraceae, Solanaceae, Anacardiaceae and Verbenaceae. A significant diversity of bee-attracting flora was evident throughout the Department.
