Abstract


The study evaluated Integrated Hive Management (IHM) strategies that would strengthen newly established bee colonies and also identified pollen spectra as well as proximate contents of honeys from Ikorodu and Badagry areas of Lagos State, Nigeria. Hive management strategies which involved monitoring for insect pests and diseases of honeybees were put in place at the University of Lagos (Unilag), Badagry and Ikorodu apiaries. Pests encountered were recorded while preventive and therapeutic measures were implemented. Honey samples collected were analyzed for mellisopalynology and proximate contents. Adult insect pests found at the Unilagapiary were the small hive beetle, Aethina tumida Murray (17), the lesser Wax moth, Achroia grisella Fabricius (2) and Varroa mite, Varroa destructor Anderson and Trueman (2). Other nuisance pests such as ant species were common to all the apiaries. The result of the mellisopalynology showed that the Badagry honey samples recorded 9273 pollen grains distributed among 32 families and 51 species while the Ikorodu honey samples recorded 8564 pollen grains and spores distributed over 29 families and 46 species. The Badagry honey samples had abundance of Nymphaea lotus, Adenia species, Raphia species and Typha pollen. The abundance of N. lotus was expected due to the close proximity of the apiary to swampy vegetation. The presence of Corchorus and Solanaceae pollen in Ikorodu honey confirmed the closeness of a farmland to the apiary. A fern spore, cf. Thelypteris species was recovered from Ikorodu honey. The proximate content showed that honeys from the apiaries had water content of 19.4% and 19.8% while protein was 0.44% and 0.43% for Ikorodu and Badagry respectively.
