Bee fauna potential visitors of coriander flowers Coriandrum sativum L. (Apiaceae) in the Mitidja area (Algeria)

Abstract

Abstract Coriander Coriandrum sativum L. (Apiaceae) is a year-round condiment and aromatic Mediterranean plant. It is cultivated in several countries in North Africa, in Europe, and Western Asia. In the El Harrach area of Algiers, the insect fauna visiting crop flowers includes Diptera (Syrphidae), Coleoptera, and Hymenoptera such as Chrysididae, Vespoidea, and Apoidea (Bees). The latter super-family comprises the majority of insect pollinators. Visiting bees belong to four families: Apidae, Andrenidae, Halictidae, and Colletidae. The main visitors are honeybees and six species of Andrenidae: Andrena flavipes, Andrena thoracica, Andrena lagopus, Andrena bimaculata, Andrena discors, and Andrena cinerea elliptica. The three species Andrena lagopus, Andrena bimaculata, and Andrena cinerea elliptica have 100% pollinating visits while Apis mellifera has only 63%. Andrena cinerea elliptica is the most frequent and the most abundant species.
