Role of two agrosystems (mango and cashew trees orchards) in bees' activity increasing within beehives in Korhogo, Northern Ivory Coast (West Africa) ‎

This work aimed to assess the impact of different agrosystems on bees’ activity in beehives. Pan traps (UV-bright yellow, white and blue) were used to sample insects particularly honey bees and wild bees within mango and cashew orchards and compare them with those in unmanaged savanna. Ten beehives were installed in each agrosystem in order to monitor bees’ activity. A total of 283 bee specimens were caught during three months. The bee specimens found revealed three families (Apidae, Halictidae and Megachilidae). Halictidae were the most diversified family with 8 ± 0.01 species. A total of 33 species assigned to 17 genera were found. According to data analysis, the average bee richness and the average bee abundance were greater in mango and cashew orchards. Bees’ activity was also more intense in beehives installed in mango and cashew orchards. It evolves with temperature up to a threshold and inversely with relative humidity. It is maximum between 11am and 2pm at temperatures between 34°C and 35°C and with a relative humidity between 56% and 65%. This study highlights the role of cashew and mango orchards in the conservation of bee populations, in particular honey bees ‘’Apis mellifera’’ (dominant species), mainly responsible for honey production and associated products (eg. wax, propolis and royal jelly) in our regions. The positive impact of these agrosystems on bees’ activity is beneficial for beekeepers and even, could help to provide pollination service in agricultural areas, effectively.
