Abstract

En este estudio se presenta la diversidad y abundancia de las abejas del PNN Gorgona. En tres visitas en intervalos de tres meses, se muestrearon seis zonas de la isla con cubierta vegetal variable. Los muestreos fueron indirectos usando (i) trampas McPhail (cebadas con cineol, silicato de metilo y extracto clavos); (ii) trampas Van Someren Rydon (con cebo de pescado o pollo o fruta podridos), (iii) trampas Malaise y (iv) trampas de luz y directos a lo largo de transectos de longitud indefinida, por períodos de una hora en cada área y se repitieron cuatro veces. Un total de 585 especímenes fueron capturados, de ellos, 443 pertenecen a Apidae (14 géneros), 141 a Halictidae (seis géneros) y uno a Megachilidae. Con este informe, el inventario local de Abejas se eleva a 43 especies y 28 géneros. Trigona fulviventris guianae Cockerell, 1910 fue la especie más abundante, Euglossa ignita Smith, 1874 la más atraída por los cebos aromáticos y Megalopta genalis Smith, 1853 dominó durante la noche. Apis mellifera Linnaeus, 1758 no se encontró en los muestreos. La importancia de la Isla Gorgona, como sitio de la diversidad para las especies de abejas es discutida.

Bees (Hymenoptera: Apoidea) of Gorgona Natural National Park, Colombian Pacific. The National Natural Park Gorgona is a continental island off the Colombian Pacific coast. Bees have a specialized and crucial role in this isolated and unique ecosystem and here we assess their biodiversity. In three visits, at intervals of three months, six areas of the island with variable vegetation cover, were sampled. Sampling was done indirectly using (i) McPhail traps (baited with cineole, methyl silicate and clove oil), (ii) Van Someren Rydon traps (baited with rotting fish, chicken or fruit), (iii) Malaise traps and (iv) light traps. In addition, a direct sampling was carried out along transects of indeterminate length, for periods of one hour in each area and repeated four times. A total of 585 specimens was captured, of these 443 belong to Apidae (14 genera), 141 to Halictidae (six genera) and one Megachilidae. With this report the local inventory of bees rises to 43 species and 28 genera. Trigona fulviventris guianae Cockerell, 1910 was the most abundant species, Euglossa ignita, the most attracted to aromatic lures and Megalopta genalis Meade-Waldo, 1916 was the dominant species during evening hours. The absence of Apis mellifera was noticeable. Rev. Biol. Trop. 62 (Suppl. 1): 297-305. Epub 2014 February 01.

The Bees of the World

Charles D. Michener (2007)

In this extensive update of his definitive reference, Charles D. Michener reveals a diverse fauna that numbers more than 17,000 species and ranges from the common honeybee to rare bees that feed on the pollen of a single type of plant. With many new facts, reclassifications, and revisions, the second edition of The Bees of the World provides the most comprehensive treatment of the 1,200 genera and subgenera of the Apiformes. Included are hundreds of updated citations to work published since the appearance of the first edition and a new set of plates of fossil bees. The book begins with extensive introductory sections that include bee evolution, classification of the various bee families, the coevolution of bees and flowering plants, nesting behavior, differences between solitary and social bees, and the anatomy of these amazing insects. Drawing on modern studies and evidence from the fossil record, Michener reveals what the ancestral bee—the protobee—might have looked like. He also cites the major literature on bee biology and describes the need for further research on the systematics and natural history of bees, including their importance as pollinators of crops and natural vegetation. The greater part of the work consists of an unprecedented treatment of bee systematics, with keys for identification to the subgenus level. For each genus and subgenus, Michener includes a brief natural history describing geographical range, number of species, and noteworthy information pertaining to nesting or floral biology. The book is beautifully illustrated with more than 500 drawings and photographs that depict behavior, detailed morphology, and ecology. Accented with color plates of select bees, The Bees of the World will continue to be the world's best reference on these diverse insects.
