RAMIREZ FREIRE, Liliana et al. Using pan traps and netting to collect native bees in Nuevo León state, Mexico. Acta Zool. Mex [online]. 2014, vol.30, n.3, pp.508-538. ISSN 2448-8445.

A wildlife study was carried out on native bees in the state of Nuevo Leon, northeast Mexico; color bowl traps and netting were used as sampling technique. A total of 3,952 individuals were collected, in five families, 47 genera and 191 species, also, adding those species recorded on literature and existing databases the species number raised to 317. A total of 73 species were collected by color bowl traps and 68 species were collected using entomological net, 48 species were collected using both methods. Seven genera and 32 species are reported for the first time for the state of Nuevo Leon. Higher abundance and species richness were recorded on color bowl traps, and higher diversity was recorded on entomological net. Yellow bowl traps captured the highest bee abundance, diversity and richness being Halictidae the best represented family. During entomological net sampling a total of 21 plant families were identified as visited by bees, plant families with highest bee abundance were Scrophulariaceae, Asteraceae and Fabaceae, highest bee diversity was recorded on Asteraceae. Discussion about number of species collected and accumulation curve are presented also on collection methods.
