CHECKLIST, DIVERSITY AND DISTRIBUTION OF WILD BEES (HYMENOPTERA: APOIDEA ; ANTHOPHILA ) ACROSS TLEMCEN MOUNTAINS, IN THE NORTH WEST OF ALGERIA.

Abstract

Our study concerns the diversity and distribution of wild bees through three sites in the Tlemcen mountains. T he present paper contains a che cklist of 155 taxa with three new records for the Apoid fauna of Algeria. These are Andrena marginata Fabricius, 1776, Anthidium manicatum Dallatour, 1877 and Megachile latimanus Say, 1823. The index study and the statistical treatments applied to th e r esu lts made it possible to highlight the composition of this fauna, its dependence on floral resources and its spatio temporal distribution across the region . The results obtained reveal a high richness of Apoids in this region, the conservation of whic h i s n ecessary in the future as this fauna plays a key role in the pollination of plants and their diversity within natural and agricultural ecosystems.
