“…Overall, the species collected in this survey (Table 1) were representative of Nova Scotia's cavity-nesting bee fauna (Sheffield et al 2003); Sheffield (2006) and Cane et al (2007) recently reviewed the nesting biology of many of these species. Species richness and abundance (i.e., total numbers reared) were expected to be highest within less managed habitats, high similarity was expected among sites within each habitat type, and differences were expected among habitat types based on the management practices in each.…”

“…Cavitynesting bees, especially those of the family Megachilidae, have shown the greatest potential for development as manageable pollinators, as many species readily accept artificial nesting materials, including trap nests (Krombein 1967;Stubbs and Drummond 2001;Cane et al 2007). Trap nests have been used to study nesting biology (e.g., Krombein 1967), develop and evaluate potential crop pollinators (e.g., Torchio 2003), conduct studies of species diversity (e.g., SteffanDewenter 2002SteffanDewenter , 2003, and provide additional nesting sites for increasing and conserving bee populations (e.g., Stubbs and Drummond 2001).…”

Abstract-Solitary cavity-nesting bees, especially trap-nesting Megachilidae, have great potential as commercial pollinators. A few species have been developed for crop pollination, but the diversity, abundance, and potential pollination contributions of native cavity-nesting bees within agricultural systems have seldom been assessed. Our objectives were to compare the diversity and fecundity of cavity-nesting bees in Nova Scotia in natural ecosystems with those in apple orchards under three levels of management, using trap nests, and to determine whether any native bees show promise for development as pollinators. Our results show that species richness and numbers of bees reared from trap nests in commercially managed orchards, abandoned orchards, and natural habitats were similar, and species' compositional patterns were not unique to specific habitats. Trap nests can be used to increase and maintain cavity-nesting bee populations within Nova Scotia apple orchards. Osmia tersula Cockerell (Megachilidae), which accounted for almost 45% of all bees captured and was the most abundant species nesting in all habitats evaluated, should be assessed for potential as a commercial pollinator of spring-flowering crops. The influence of natural cavities on bee species richness in trap-nesting surveys is also discussed.Résumé-Les abeilles solitaires qui nichent dans les cavités, particulièrement les Megachilidae qui logent dans les nids-pièges, représentent un important potentiel de pollinisateurs commerciaux. Quelques espèces ont été utilisées pour la pollinisation des cultures, mais on a rarement évalué la diversité, l'abondance et la contribution potentielle à la pollinisation des abeilles qui nichent dans les cavités dans les systèmes agricoles. Notre objectif est de comparer à l'aide de nids-pièges la diversité et la fécondité des abeilles qui nichent dans les cavités dans les écosystè-mes naturels et dans des pommeraies gérées sous trois régimes différents en Nouvelle-Écosse, ainsi que de déterminer s'il y a des abeilles indigènes qui offrent un potentiel pour servir à la pollinisation. Nos résultats montrent que la richesse spécifique et le nombre d'abeilles obtenues dans les nids-pièges sont semblables dans les pommeraies sous gestion commerciale, dans les pommeraies abandonnées et les habitats naturels; de plus, les patrons de composition spécifique ne sont pas propres aux différents habitats. Dans les pommeraies de Nouvelle-Écosse, les nidspièges peuvent servir à augmenter et à maintenir les populations d'abeilles qui nichent dans les cavités. Osmia tersula Cockerell (Megachilidae), qui représente presque 45 % de toutes les abeilles capturées et qui est l'espèce la plus abondante à nicher dans tous les habitats étudiés, devrait être évalué en vue d'une utilisation éventuelle comme pollinisateur des cultures qui fleurissent au printemps. Nous discutons aussi de l'influence des cavités naturelles sur la richesse spécifique des abeilles dans les inventaires faits à l'aide de nids-pièges.

“…World nest in wood as far as known (Griswold, 1986b;Cane et al, 2007;Michener, 2007), whereas their Old World relatives, most likely the group from which they have evolved, show a much more variable nesting behavior (Michener, 2007;A. Müller and C. Praz, unpublished).…”

“…In particular, the nesting biology of the Osmiini is highly varied and encompasses much of the diversity observed in other bees (Malyshev, 1937;Westrich, 1989;Müller et al, 1997;Cane et al, 2007). Depending on the species, osmiine bees build their nests in holes in the ground, below stones, on rock surfaces, in pithy stems, galls or in beetle borings in dead wood.…”

KeywordsBiogeography Bayesian analysis Maximum likelihood Ancestral Character evolution Nesting behavior a b s t r a c tThe Osmiini (Megachilidae) constitute a taxonomically and biologically diverse tribe of bees. To resolve their generic and suprageneric relationships, we inferred a phylogeny based on three nuclear genes (Elongation factor 1-a, LW-rhodopsin and CAD) applying both parsimony and Bayesian methods. Our phylogeny, which includes 95 osmiine species representing 18 of the 19 currently recognized genera, is well resolved with high support for most basal nodes. The core osmiine genera were found to form a well-supported monophyletic group, but four small genera, Noteriades, Afroheriades, Pseudoheriades and possibly Ochreriades, formerly included in the Osmiini, do not appear to belong within this tribe. Our phylogeny results in the following taxonomic changes: Stenosmia and Hoplosmia are reduced to subgeneric rank in Hoplitis and Osmia, respectively, Micreriades is recognized as a subgenus in Hoplitis and the subgenus Nasutosmia is transferred from Hoplitis to Osmia. We inferred a biogeographic scenario for the Osmiini applying maximum likelihood inference and models of character evolution. We provide evidence that the Osmiini originated in the Palearctic, and that extensive exchanges occurred between the Palearctic and the Nearctic. The latter finding may relate to the fact that many osmiine species nest in wood or in stems , facilitating dispersal by overseas transport of the nests.

“…Nests are excavated in the soil or built in preexisting cavities in the ground, rocks, in pithy stems, galls, or exclusively in arboreal termite nests or abandoned snail shells; nesting materials are quite diverse, including sand, mud, pebbles, resins, masticated plant material, plant trichomes, petals, and leaf pieces. Some taxa are predominantly composed of pollen generalists or polyleges, while others contain mostly pollen specialists or oligoleges, the latter often exhibiting interesting behavioral and morphological specializations to collect and manipulate the pollen (e.g., Mü ller 1996, Cane et al 2007, Michener 2007, Gonzalez 2008, Rozen et al 2010.…”
