Abstract Bendifallah, L., K. Louadi and S.E. Doumandji. 2010. A Study on Wild Bees as Pollinators of Weeds and Herbal Medicinal Plants in Matija Region, . Arab Journal of Plant Protection, 28: 107-113. This study aimed to identify the most important wild bee species prevalent around wild and herbal medicinal plants, estimate their numerical density and effectiveness in pollination when visiting flowers during winter, spring and summer of 2003 and 2004 at the experimental station of the National Institute of Agricultural Sciences, Algeria. The study revealed the occurrence of the following seven different bee genera: Bombus, Osmia, Anthophora, Halictus, Andrena, Eucera and Xylocopa. Distribution of each depended on the preferred plant and climatic conditions. Species belonging to the genera Halictus, Anthophora, Bombus, Eucera and Xylocopa were found to be the most prevalent in April. While those of the genera Osmia and Andrena were found in May. The bee species Anthophora atriceps was the most active in visiting flowers compared to the other species at the rate of 30 flowers per minute. The least active species was Andrena albopunctata funebris which visited 3 flowers per minute. Keywords: Wild bees, herbal medicinal plants, pollination, Algeria.
