The aim of this work was the melissopalynologycal analysis of the honey samples collected both during the dry and rainy seasons of the three phyto-geographical zones of Benin. The analysis was performed by conventional methods on 60 honeys samples. The total of 138 taxa have been identified at family level (31), genus level (20) and to the level species (87). The number of pollens counted varies according to the phyto-geographical zones. Thus, 17091 pollens have been counted in the samples of the Sudanian zone; 13884 in those of the Sudano-Guinean zone and 7960 pollens in those of the Guinean

The potential of honey production by honeybee in one area are determined by the flora. This study aims to evaluate the structural characteristics of Syzygium guineense subsp. macrocarpum so as to propose its promotion for beekeeping in Benin. Some structural variables were collected through 18 plots of one hectare (100 m x 100 m). It was installed at random in three classified forests in sudano-guinean zone. Each plot was divided into 16 plots of 625 m² (25m x 25m). For all species of tree and shrub, the stems of dbh ≥ 10 cm have the highest values of density (549 stems/ha) and landed surface

A total of 96 adult guinea fowl, aged at least 6 months, were selected for blood sampling. Fragment analysis was carried out using 17 polymorphic microsatellite markers. The informative marker combinations revealed a total of 83 alleles across all loci, with an average of 5 alleles per locus and a mean polymorphic information content (PIC) of 0.793.
