Abstract
Beekeeping, based on the management of the honeybee Apis mellifera, is an activity of significant economic, social, and environmental importance in the Soconusco region located at southern of Mexico. It provides income for rural communities and contributes to the pollination of both wild and cultivated plants. The region exhibits high botanical diversity, including native species such as Byrsonima crassifolia, Gossypium hirsutum, and Chrysobalanus icaco, as well as exotic and cultivated species such as Coffea canephora, Mangifera indica cv. Ataulfo, Anacardium occidentale, and Nephelium lappaceum. The flowering of these species supplies essential resources-mainly pollen and nectar-that are collected by bees and reflected in the botanical and organoleptic diversity of local honeys. In this context, the development of a pollen atlas of melliferous flora in this region is fundamental for the palynological identification and characterization of honey, enabling the identification of the main floral sources used by Apis mellifera. This supports the sustainability and traceability of regional apiculture.
