“…Studies on the residual pollen content from nests of T. diversipes in different ecosystems showed that unrelated plant species of Dalechampia L. (Euphorbiaceae), Ludwigia L. (Onagraceae), and Pereskia Mill. (Cactaceae), all of them characterized by large pollen grains, are known as pollen sources (Menezes et al 2012;Lyra-Neves et al 2014;Rocha-Filho and Garófalo 2016). Additionally, the main source of pollen for the two Tetrapedia species, Pereskia grandifolia Haw., bloomed throughout all the year (Rocha-Filho and Garófalo 2016) and was located at the forest edge, where most of T. diversipes nests and all nests of T. aff.…”

Low trophic niche overlap among trap-nesting bee species (Hymenoptera: Anthophila) in a semideciduous forest fragment

Bees are important components of mutualistic interactions with plants, playing a key role as pollinators of both wild and crop plants. In this context, studies on the plants visited by bees are important to determining conservation strategies. We investigated the use of floral resources by the trap-nesting bee species sampled in a semideciduous forest fragment. Trap nests were set in the forest fragment in three different zones: forest edge, 250 m away from the edge and 500 m away from the forest edge. Pollen analysis of the residual pollen content removed from the nests of 12 bee species revealed a total of 63 pollen types from 16 botanical families. The bee community showed specialized populations with no overlap in diet. Within the community, the diet overlap was higher in closely related species, the two Tetrapedia species and the two Centris (Heterocentris ) species, than in the other sampled species. Although the studied bee community is composed of widespread bee species, our data showed a low niche overlap among them, suggesting the occurrence of food niche partitioning at our study site. The asymmetry in the period of nesting activities and floral preferences among the bee species are factors that might have contributed to the low niche overlap observed.cavity-nesting bees / diet breadth / floral oil / nectar / pollen / specialized populations

“…Cover traps with wire mesh (e.g., chicken wire) Ant predation Barrier of sticky resin (e.g., tanglefoot ® ) excludes ants (Miyano & Yamaguchi, 2001) and other flightless insects (e.g., earwigs: Barthell et al, 1998); replace barrier regularly; when trap nests are attached to posts, an oil-filled chamber at the bottom of the post is also effective (Rocha-Filho & Garófalo, 2016) Water in trap Slit on the underside of the plastic tube drains water; for other trap nest designs, a roof can help…”

“…In tropical regions, ants often occupy trap nests, which lower nesting activity (Miyano & Yamaguchi, 2001) and can prey on bees and wasps. Regularly inspected barriers consisting of sticky resin exclude ants and other flightless nontarget insects such as earwigs (Barthell, Frankie, & Thorp, 1998) and other methods have also been used (e.g., Rocha-Filho & Garófalo, 2016). Trap nests should also be protected against birds, e.g., by covering the traps with wire mesh because some insectivorous birds (e.g., tits and corvids) may dismantle traps to feed on the contents.…”

Trap nests for bees and wasps to analyse trophic interactions in changing environments—A systematic overview and user guide

et al. 2018

Trap nests are artificially made nesting resources for solitary cavity‐nesting bees and wasps and allow easy quantification of multiple trophic interactions between bees, wasps, their food objects and natural enemies. We synthesized all trap nest studies available in the ISI Web of Science™ to provide a comprehensive overview of trap nest research and identify common practical challenges and promising future research directions. Trap nests have been used on all continents and across climate zones and publication numbers have increased exponentially since the first studies in the 1950s. Originally used for detailed exploratory natural history observations, trap nests are now also an established method in hypothesis‐driven ecology and to assess environmental changes. We identify the potential of trap nests for environmental monitoring by assessing trophic interaction networks of the groups involved. While pollen collection by bees or prey hunting by wasps has often been addressed, and interactions with natural enemies were included in almost half of all publications, surprisingly few studies have quantified trophic interaction networks in response to natural and anthropogenic environmental changes. By simultaneously revealing a multitude of trophic interactions, trap nests have the potential to broaden our understanding how species interaction networks are influenced by manifold environmental changes, which are pressing topics in ecological research. To foster the use of trap nests in future studies, we identify common challenges and offer guidance on practical solutions.

“…Due to this diapause, the developmental time of G2 individuals may be four times longer in comparison to G1 (Alves-dos-Santos et al 2002). In addition to this interesting developmental aspect, T. diversipes is an attractive species to study because (i) it easily nidifies in trap nests (Camillo 2005;Alves-dosSantos et al 2006;Menezes et al 2012;Neves et al 2012;Rocha-Filho and Garófalo 2015), (ii) it has already characterized molecular markers , and (iii) its genome is currently being sequenced. In combination, all these characteristics make T. diversipes a promising emerging model for developmental and evolutionary studies on bees in tropical climates.…”

RNA-Seq reveals that mitochondrial genes and long non-coding RNAs may play important roles in the bivoltine generations of the non-social Neotropical bee Tetrapedia diversipes

-In animals, voltinism is a result of evolutionary adaptations to environmental conditions. These evolutionary adaptations may profoundly affect the population structure and social organization level. To study the bivoltinism of the solitary bee Tetrapedia diversipes , we performed comparative transcriptomics analyses of foundresses and larvae from the two reproductive generations (G1 and G2) produced per year by this bee. Most of the differentially expressed genes (DEGs) were found between foundresses: 52 DEGs between adults, but only one between the larvae. Among the DEGs in foundresses, 46 were higher expressed in G1 and most of them (38) have no functional annotation defined in the database. Interestingly, mitochondrial genes and long non-coding RNAs were the only type of identified transcripts in the set of upregulated genes. These results highlight the importance of developing studies on non-model species and suggest that maternal genes may be of importance for determining larval diapause in T. diversipes .transcriptome / bivoltinism / diapause / solitary bee / RNA-Seq
