“…Most species of natural enemies parasitized only one species of host, even Anthrax , which is a generalist species (Araujo et al 2018;Lima et al 2018 Buschini and Fajardo 2010), and there was specificity in their interactions, the same occurring between the species of Coelioxys , C. tarsata , and Megachile (Moureapis ) sp. Parasitoid and insects species richness, in general, has been found to be positively correlated with vegetation diversity and plant architectural complexity (Stinson and Brown 1983;Hawkins and Lawton 1987) which may then spill over to adjacent habitats (Tscharntke et al 2005), although in this study, and in those also carried out in the state of Paraná, southern Brazil (Iantas et al 2017), the greatest richness and abundance of wasps and bees and their parasitoids have been found always in the matrices where the forest was totally removed, and which are the environments with less structural complexity. We need to be very careful in interpreting these results because it is quite possible that trap nests in these areas had higher colonization rates because there are few other nesting opportunities available due to the lack of trees, and thus, the artificial nests become highly attractive for cavity-nesting bees and wasps.…”

Trophic interaction and diversity of cavity-nesting bees and wasps (Hymenoptera: Aculeata) in Atlantic forest fragments and in adjacent matrices

The Brazilian Atlantic Forest is on the list of the 35 world hotspots with priority for conservation because it is home to one of the most diversified and threatened fauna and flora in the world. We studied the diversity and the food webs of cavity-nesting bees and wasps and their natural enemies (parasitoids and kleptoparasites) in three Atlantic forest fragments and adjacent matrices. Although the species composition in the forest fragments was different from the adjacent matrices, the alpha diversity stayed constant. Since the structure of the interaction networks between these species has not been altered with habitat simplification, we conclude that these relations are not shaped by recent environmental changes, but by phylogenetic relations established at a more remote time.

“…In young regrowth forests, communities of bees and wasps changed with increasing canopy cover. It is known that cavity-nesting Hymenoptera species compositions are distinct for forest interiors and forest edges (Oliveira et al 2017 ; da Rocha-Filho et al 2017 ) and change with forest modification (Iantas et al 2017 ; Nether et al 2019 ). Likewise, young forests can be expected to harbor different communities, sometimes even with more species compared to old-natural forests (Yeeles et al 2017 ; Araújo et al 2018 ).…”

“…After forest clearance, the regrowth is typically characterized by non-forest species, but forest insects naturally disperse from surrounding forests into new forest plantations and re-establish species-rich communities within the first years of forest growth (Hilt and Fiedler 2005 ; Yeeles et al 2017 ; Araújo et al 2018 ; Hethcoat et al 2019 ). For example, comparing forest interiors to forest edges, or following forest thinning, removal and restoration, cavity-nesting bees, wasps and their natural enemies had comparable species numbers, but showed distinct community compositions (Oliveira et al 2017 ; Iantas et al 2017 ; da Rocha-Filho et al 2017 ; Araújo et al 2018 ; Nether et al 2019 ). Within these and further studies, plant diversity, biomass, canopy area and microclimate are discussed as drivers of multi-trophic forest insect communities (Stangler et al 2015 ; Mayr et al 2020 ).…”

Multi-trophic communities re-establish with canopy cover and microclimate in a subtropical forest biodiversity experiment

et al. 2021

Plant diversity affects multi-trophic communities, but in young regrowth forests, where forest insects are in the process of re-establishment, other biotic and also abiotic factors might be more important. We studied cavity-nesting bees, wasps and their natural enemies along an experimental tree diversity gradient in subtropical South-East China. We compared insect communities of experimental young forests with communities of established natural forests nearby the experiment and tested for direct and indirect effects of tree diversity, tree basal area (a proxy of tree biomass), canopy cover and microclimate on bee and wasp community composition, abundance and species richness. Finally, we tested if the trophic levels of bees, herbivore-hunting wasps, spider-hunting wasps and their natural enemies respond similarly. Forest bee and wasp community composition re-established towards communities of the natural forest with increasing tree biomass and canopy cover. These factors directly and indirectly, via microclimatic conditions, increased the abundance of bees, wasps and their natural enemies. While bee and wasp species richness increased with abundance and both were not related to tree diversity, abundance increased directly with canopy cover, mediated by tree biomass. Abundance of natural enemies increased with host (bee and wasp) abundance irrespective of their trophic position. In conclusion, although maximizing tree diversity is an important goal of reforestation and forest conservation, rapid closure of canopies is also important for re-establishing communities of forest bees, wasps and their natural enemies.

“…Taxonomical impediment is an important issue in many insect studies (Oliveira et al, 2011;Begum et al, 2011;Jordaens et al, 2013), including in trap-nesting bee studies . Reliable identification is necessary when using bees as ecological indicators (Tscharntke et al, 1998) even if morphospecies can be used in some diversity metrics and analyses (Magurran, 2004;Tylianakis et al, 2007;Pereira-Peixoto et al, 2014;.…”

What do we know about Neotropical trap‑nesting bees? Synopsis about their nest biology and taxonomy

Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence trap-nests (man-made cavities) provide the means by which these bees may be studied. Trap-nests is an efficient methodology to study these bees and are common worldwide. These traps have been used for a variety of reasons, including inventories, to examine pollen load, to study habitat disturbance, and bee conservation. However Neotropical trap-nesting bees’ taxonomy and biology are still poorly known and here we provide a review about these subjects. We searched for trap-nest bee studies in the Neotropical Region using Google Scholar and ISI Web of Science at any time in the past to December 2017. We found 109 independent studies, most of which were from Brazil (87 studies), followed by Argentina (10 studies), and other countries had fewer than five studies each. A total of 140 species, 24 genera, 10 tribes and three subfamilies were reported in trap-nests. Nest architecture was described for only 49 species. Taxonomy is only well-known for 14 genera, somewhat known for seven and is essentially unavailable for three genera. Construction material, closing plug and cell shape are similar among species in the same tribes and genera. Vestibular and intercalary cells, and the preliminary plug are variable, even at the specific level. Apinae is the most studied group with available data for all genera recorded in trap-nests. Colletinae is the least-studied group and nothing is known for their nesting biology. Megachilinae is intermediate, with some studies of taxonomy and nesting. We suggest that further trap-nest studies should provide more detailed information on nest architecture and construction materials, including explicit mention of structures that are absent. All Neotropical bees need more taxonomic studies, but some, such as Hylaeus and Megachile, require more attention since Hylaeus is essentially unknown and Megachile is very common on trap-nests.
