Nineteen samples of honey were collected from different localities of the Borana Zone and examined to identify the botanical origin of honey through honey pollen analysis. From nineteen honey samples, sixteen were identified as monofloral honeys. Twenty-eight plant species were identified as honey source plants and the identified plant species belo...

Pollination is a critical link in the functioning of ecosystems, and it improves the yield of crops. Insect pollination is an essential input in the production of crops grown worldwide. Of the approximately 300 commercial crops about 84% are insect pollinated. Honeybees are responsible for 70-80% of insect pollination. This indicated how much honey...
