| Summary: | Over a twelve-month period, pollen loads transported by Scaptotrigona fulvicutis Moure 1964 were collected from the workers corbiculae right after the hive entrance closure in an area of old secondary forest mixed with some exotic fruit trees and ornamentals. Once the pollen grains were identified, their monthly frequency in the samples and grouping by botanical family established that Mimosaceae, Myrtaceae and Sapindaceae were the most frequently visited. The workers harvested the pollen from 97 plant species distributed in 73 genera and 36 families, mostly: Stryphnodendron guianense (Aubl.) Benth. in April (57,37%) and Schefflera morototoni (Aubl.) Frodin in May (54,73%). The harvested pollen types abundance matrix showed that there was little species dissimilarity between the months, which resulted in the formation of two large groups.<br>Durante o período de doze meses, o pólen transportado por Scaptotrigona fulvicutis Moure 1964 foi coletado das corbículas das operárias, logo após o fechamento da entrada das colméias. Feita a identificação polínica dos grãos, sua freqüência mensal nas amostras e o agrupamento por famílias botânicas, constatou-se que as mais visitadas foram: Mimosaceae, Myrtaceae e Sapindaceae. As operárias coletaram o pólen de 97 espécies de plantas distribuídas em 73 gêneros e 36 famílias, sendo as mais freqüentes: Stryphnodendron guianense (Aubl.) Benth. em abril (57,37%) e Schefflera morototoni (Aubl.) Frodin em maio (54,73%). A matriz de abundância dos tipos polínicos coletados mostrou que a dissimilaridade de espécies entre os meses foi pequena o que resultou na formação de dois grandes grupos. |
