Abstract:
A study was conducted for determination of bee species composition that visits onion (Allium cepa L.) in Western Rajasthan. It is a biennial plant, best cultivated in fertile soils having good drainage. In Western Rajasthan,the seed yields of A. cepa crops may often be lower than the expected, because of adverse climatic, edaphic or cultural factors, but also because of the inadequate number of bee pollinators. In absence of bee pollination, fruit or seed set is affected adversely even if all the cultural practices are followed meticulously. Bee pollinators start visiting early flowers of the crop and increase quality and quantity of the seed yield. The collection on flowerings and identification of bee species revealed that the crop is visited by 16 species of Apoidea. They belong to various families: Halictidae (06 spp.: Nomiaelliotii Smith, Pseudapis tegulata Smith, Lasiogl ossum spp., Halictus spp., Ceylalictus spp., Nomioides spp.); Apidae (06 spp.: Crocisa ramose Lepeletier, Ceratina propinqua Cameron, Ceratina sexmaculata Smith, Amegilla quadrifasciata de Villers, Amegillaniveo-cincta Smith, Epeolus spp.), Megachilidae (04 spp.: Megachiles tirostoma Cameron, Megachile argentata Spinola, Megachile creusa Bingham, Megachile studiosa Bingham), The study concluded that there was no visitor identified in family Andrenidae, Colletidae and Melittidae on this crop in the specified area. Onions are cultivated and used around the world as a food item. They are usually served cooked, as a vegetable or part of a prepared savoury dish, but can also be eaten raw or used to make pickles or chutneys. The paper presents apprehension about the effectiveness of this visitor’s on the referred crop for the first time.
Key words-  Allium cepa L., Apoidea, Megachilidae, Halictidae, Apidae, Western Rajasthan
