The present work is a contribution to knowledge of polen recovered from six Apis mellifera honey samples and six pollen loads samples, in order to characterize their botanical and geographical origin. Samples were collected from central and northern Guerrero -both regions of beekeeping importance- during November-December 2005 and March 2006. Honeybee foraging behavior was also analyzed. Melissopalynological results showed a total of 43 pollen types belonging to 27 families; only 15 taxa of native flora were considered of importance, and their palynological descriptions are included: Cosmos sulphureus, Dyssodia papposa, Taraxacum campylodes, Tithonia tubaeformis, and Vernonia sp. (Asteraceae), Coutoubea sp. (Gentianaceae), Dalea sp. and Leucaena leucocephala (Fabaceae), Quercus sp. (Fagaceae), Miconia sp. (Melastomataceae), Pisonia sp. (Nyctaginaceae), Dodonaea viscosa and Paullinia sp. (Sapindaceae), Solanum sp. (Solanaceae), and Heliocarpus donnellsmithii (Malvaceae) as well as Zea mays (Poaceae), an abundant crop. Two oligofloral and four multifloral honey samples were characterized. Diversity indexes varied from 1.7 to 2.3 in honey samples, while the pollen loads registered 1.6 to 2.1 values in diversity, the evenness index in honey samples varied from 0.8 to 0.9, whereas pollen load samples registered a range from 0.6 to 0.9. Apis mellifera showed polylectic behavior; the herbaceous stratum was the most foraged, followed in importance by tree and shrub strata.

Keywords : honeybee; melissopalynology; oligofloral and multifloral honey; pollen morphology; beekeeping region.
