Abstract
In order to assess the influence of seasons on the exploitation of mellliferous plants by Apis mellifera
adansonii, seasonal pollen spectra of 104 honey samples collected between September 2010 and
March 2011 in the Highlands area of west Cameroon (LN 5°21.459–5°35.449 and LE 10°04.729–
10°26.249) were analysed using melissopalynology methods. The aim was to evaluate the influence
of seasons on the exploitation of melliferous plants by A. mellifera adansonii. The spectrum of beeplants exploited during the rainy season was large and diversified compared to the dry season.
Asteraceae and Caesalpiniaceae were the most represented families for the dry and the rainy seasons,
respectively. Asteraceae was also the most represented family in the two seasons. The spontaneous
Eucalyptus saligna and Terminalia mantaly were much foraged during the two seasons. Flowers of
herbs were highly exploited in both the seasons and white colour flowers were frequently foraged.
Honey of rainy season was more diversified with four distinguished colours. Predominant and
important minor was significantly higher in rainy season compared to the dry season. The frequency
of pollen in honey varied considerably with seasons and availability of blooming vegetation exploited
by honeybees. Irrespective of vegetation diversity with seasonal variation, honeybee visits were very
specific to some plants species.
