Abstract

We analysed scientific production related to melissopalynology in Brazil and surveyed the pollen types described in publications, producing a melissopalynological database. We inventoried articles published between 2005 and 2017 indexed in the Web of Science (WoS) and Scientific Electronic Library Online (SciELO). Searches in WoS involved researching the terms (1) mel?ssopalynolog*, (2) pollen analy?* AND honey, (3) bee* pollen, (4) pollen NEAR/15 bee*, (5) pollen analysis of honey, and (6) pollen analy?* NEAR/15 honey; in SciELO, we used the search terms (1) melissopalinologia, (2) pólen AND mel, (3) pólen AND abelha, (4) pólen apícola, and (5) análise polínica AND mel. Additionally, we consulted the resume of the principal authors of melissopalynology research in Brazil to identify articles published during that period but not appearing in other database searches. We uncovered a total of 133 publications distributed among 56 journals, with a mean of 4.92 authors/publication. A total of 1,362 pollen types were identified, representing 130 botanical families. Among those, the most well represented in terms of numbers of pollen types were Fabaceae (270), Asteraceae (89), Euphorbiaceae (61), Rubiaceae (58), Myrtaceae (51), Malvaceae (51), Bignoniaceae (49) and Arecaceae (48). Fifty-nine bee species were mentioned in the studies, distributed among 19 genera. Apis mellifera was the most frequently mentioned bee species (73 publications), followed by the native bee species Tetragonisca angustula (13 publications). The pollen types most frequently mentioned in the articles were (in decreasing order): Eucalyptus, Myrcia, Cecropia, Mimosa caesalpiniifolia, Vernonia, Poaceae type and Croton. The inventoried publications comprised all five geographical regions of Brazil, especially the northeastern region of that country, with 59 publications. There are still large areas of Brazil without any melissopalynological studies, however, principally the central-western and southern regions. As such, more research will be necessary to fill gaps in our knowledge of Brazilian palynodiversity.
