Abstract
RAMIREZ-FREIRE, Liliana et al. Bees of the genus Agapostemon (Hymenoptera: Halictidae) of the state of Nuevo León, Mexico. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.1, pp.63-70. ISSN 2007-8706.
A study of the bee genus Agapostemon (Halictidae) in the state of Nuevo León, Mexico was carried out to learn about species numbers, distribution, relationship to flora and vegetation types of the state. Methodology was based on a review of literature and databases from enthomological collections, for field sampling net and pan traps were used in yellow, blue, pink (fluorescent colors) and white. A total of 35 sites along the state were visited, Agapostemon specimens were found only in 20 sites. We collected 11 species, 2 of them as new records for the state (A. nasutus and A. splendens). From the total specimens, 12.31% was obtained with the use of net and 87.84% using pan traps, being yellow the preferred color. The most widely distributed species were A. tyleri and A. angelicus/A. texanus. Specimens were collected from 9 plants species belonging to 6 families, Helianthus annuus (Compositae) showed the highest species diversity with 4 Agapostemon. Ten different types of vegetation which were sampled, being different brush types and perturbed vegetation the ones with higher species richness.
