Spectrum of plant species foraged by Apis mellifera adansonii Latreille in the North Sudanian phytogeographical region of Burkina Faso

Abstract

Melissopalynological analysis of 60 honey samples collected from 50 Kenyan Top Bar Hives in the North Sudanian phytogeographical region of Burkina Faso established the plant species foraged by honeybees Apis mellifera adansonii. Forty-three pollen types from 29 families were identified in the honey samples. The most common families were Mimosaceae (9.30%), Asteraceae (6.98%) and Anacardiaceae (6.98%). The most frequently visited plants were Combretum (66.66%), Tridax procumbens (66.66), Acacia seyal-group (50%), Cleome viscosa-group (50%) and Cyperus esculentus (41.67%). The results showed that Apis mellifera adansonii is polylectic with a heterogeneous foraging behaviour. Pollen analysis showed that the honeys from the two main honey flows of Burkina Faso were polyfloral.
