Abstract

Abstract The study of bee diversity and activity was conducted from January until June 1994 in a natural vegetation parcel (6200 m 2 ) in Constantine (Algeria). The results showed the presence of 10 genera of wild bees visiting natural flowers and belonging to four families: Andrenidae, Anthophoridae, Halictidae, and Megachilidae. The Apidae family was represented by honeybee ( Apis mellifera L.) and bumblebee ( Bombus ruderatus siculus Dalla Torre et Friese). Census of bee populations revealed the abundance of wild bees with 66.26% of flowers visits, honeybee with 31.98%, B. ruderatus and Xylocopa violacea with 1.59 and 0.17% of total fauna, respectively. The beginning flight activity of these species started from a minimum threshold of temperature and humidity. The alimentary specialization was quantified by Simpson’s diversity index ( I s ) and by Shannon’s diversity index ( I sh ). Apis mellifera had the highest floral visits index ( I s = 0.866) and the broadest alimentary niche index ( I sh = 0.316).
