%X A study of the most important polliniferous plants for European and Africanized honeybees (Apis mellifera L.) was made in Quintana Roo state. Comparisons were made between the plants visited by both bee types in order to determine whether there were qualitative or quantitative differences in their choice of plant species. Also some foraging strategies of the honeybees were analysed. Pollen from pollen load samples was acetolysed and mounted on slides. Subsequently the polien grains were identified, counted and photographed. A total of 206 pollen load samples were collected at Palmas and St. Teresa during two years. The most frequent species in the ponen load samples from European and Africanized honeyhees were Cecropia peltata, Metopium brownei, Lonchocarpus sp. 2, Viguiera dentata, Eragrostis sp. 1, Bursera simaruba and Eupatorium albicaule. Both types of honey bees show a high reliance on pollen from only a few species, the first five named above comprised around 50% of all the mean percentage frequencies. Families that contributed with the largest number of polien species were Fabaceae, Asteraceac, Boraginaceae, Convolvulaecae, Euphorbiaceae, Sapindaceae, Poaceac, Myrtaceae, Sapotaceae and Tiliaceae. C. peltata, Trema micrantha, B. simaruba, Eugenia sp. 1, Thouinia canesceras, Pouteria sp. 1, Mimosa bahamensis and V. dentata, were the pollen species with the largest percentages of oceurrence in both European and Africanized bee pollen load samples, and also represent a "long-term" food resources during the year. Un estudio de las plantas polin赤feras m芍s importantes para las abejas europeas y africanizadas (Apis melifera L.) se realiz車 en el estado de Quintana Roo. Se hicieron comparaciones entre plantas visitadas por ambos tipos de abejas, con el objetivo de determinar si hay diferencias cualitativas o cuantitativas en la elecci車n de la especie de planta. Adicionalmente, se analizaron algunas estrategias de forrajeo de las abejas. Muestras de cargas de p車len se acetolizaron y se montaron en l芍minas. Posteriormente, los granos de p車len se identificaron, se contaron y se fotografiaron. Se recolectaron un total de 206 muestras de cargas de p車len en Las Palmas y Sta. Teresa durante dos a os. Las especies m芍s frecuentes en las muestras de cargas de p車len fueron Cecropia peltata, Metopium brownei, Lonchocarpus sp. 2, Viguiera dentata, 1, Eragrostis sp. 1, Bursera simaruba y Eupatorium albicaule. Ambos tipos de abejas mostraron una alta dependencia hacia s車lo unas pocas especies de plantas, las primetas cinco de las mencionadas anteriormente constituyen apr
