“…However, a lack of taxonomic knowledge on these insects has made it difficult to do a comprehensive comparison. The fungal infestation as one of the main causes of immature mortality of trap-nesting bees (Antonini et al, 2003;Camarotti-de-Lima & Martins, 2005;Stangler et al, 2016), and the present study support this. This is probably due to the period of highest activity of bees coincides with high rainfall in the region.…”

The solitary bees that use preexisting cavities can be captured in trap-nests allowing to collect data on nesting biology and associated organisms. This man-made trap-nest facilitates the understanding of environmental components and landscape composition in the fauna of solitary bees. Here, we aimed to increase the knowledge about trap-nesting bee species from four protected areas Atlantic Forest in southeastern Brazil and to test how abiotic local environmental components (temperature and rainfall) and forest cover affects the trap-nesting bee fauna. We recorded occupants from 847 nests founded by 17 bee species and seven cleptoparasite bees, associated to their host, summing 24 bee species sampled. The family with highest species richness was Megachilidae, and the species with the largest number of founded nests was Tetrapedia diversipes Klug (Apidae). Diptera, coleoptera, and hymenoptera parasitized 15.2% of the founded nests. The period of highest nest occupation occurred between November and February, which correspond to the warmest and most humid months in the region. We found significant positive correlation between the number of nests and monthly accumulated rainfall. We verified that Boraceia and Ilhabela have the best status conservation based on native forest cover and we sampled the highest diversity of species in these areas. We improved the knowledge on trap-nesting bees communities from Atlantic Forest on new species sampled in this biome with their nesting biology and highlighted that rainfall influences positively the nest founding throughout the year and native forest cover influences diversity of species.

“…Wilms (1995) also recorded a seasonal pattern of activity for megachilids associated with the summer in the Atlantic Forest of Boraceia, São Paulo. According to Camarotti-de-Lima and Martins (2005), many megachilid bees from tropical regions are bi-or multivoltine. Despite a lot of studies conducted in many parts of the world, more species of leafcutting bees, particularly from the tropical region, need to be studied over a wider range of climates and biomes to assess whether megachilids generally pass part of the year in diapause.…”

-Studies on the nesting biology of cavity nesting hymenoptera (bees and wasps) have stimulated many questions related to the behavior, life cycle, trophic niche, and sex ratio to better understanding of the life history of insects. Leafcutting bees are common insects, and many are important and efficient pollinators of crops and other plants. We studied the nesting biology of Megachile (Moureapis ) maculata in a montane semi-deciduous forest in Brazil using trap nests in order to improve the knowledge of aspects of the natural history of this important pollinator group. During 27 months, 87 nests were collected with an average of seven brood cells per nest. Most of the nests were in cavities of 0.9 cm in diameter (77%), and the number of brood cells ranged from 1 to 11. Absence of seasonality in nesting behavior suggests a multivoltine species. The total mortality rate was 26%, with the cuckoo bee Coelyoxis (Acrocoelioxys ) sp. being the main natural enemy attacking 15% of brood cells. The sex ratio is clearly male-biased (1:0.42). Females and their brood cells were larger than males and their brood cells, which may suggest an imbalance in the energetic cost of each sex. The success of this bee species in colonizing trap nests makes it an interesting potential opportunity to use this species for pollination of cultivated Asteraceae plant species, like sunflower.Atlantic forest / sex ratio / solitary bees / trap nests INTRODUCTIONThe genus Megachile Latreille, 1802 (Megachilidae) is large, with 1524 species described, of which 147 have been recorded from Brazil (Ascher and Pickering 2015). Species of megachilid bees use several nesting substrates. Some species dig nests in the soil, but most are specialists in using pre-existing cavities in the ground, among rocks or in pithy stems and galls (Eickwort et al. 1981). Pre-existing cavities are also found in dead wood, such as old galleries of wood-dwelling beetles, which are important nest spaces in forest ecosystems (Zuo et al. 2016).Materials used for nesting construction are quite diverse, including sand, mud, resins, plant trichomes, petals, and leaf pieces. The behavior of nesting in cavities probably evolved repeatedly in ancestral species that nested in the soil (Eickwort et al. 1981) and may be more common than once supposed. Females, particularly of the genus Megachile , use their mandibles to cut pieces of leaves used to build their brood cells. This remarkable behavior, of using pieces of leaves to build the brood cells, is unique among bees.

“…Some studies have investigated the nesting biology of solitary bee species inhabiting the Atlantic coastal plain (Viana et al, 2001;Aguiar & Martins, 2002; Camarotti-de-Lima & Martins, 2005;Bernardino & Gaglianone, 2008;Martins et al, 2014). Some of these cavity-nesting bee species, such as Centris and Xylocopa spp.…”

Some solitary bees establish their nests in preexisting cavities. Such nesting behavior facilitates the investigation of their life history, as well as the monitoring of their populations in natural, semi-natural and cropped habitats. This study aimed to evaluate the acceptance of artificial substrates by cavity-nesting bees in a heterogeneous landscape. We investigated the percentage of occupation of the different trap-nests, the monthly fluctuations in the nesting activity, offspring sex ratio, mortality and parasitism, in two phytophysiognomies: herbaceous-shrub restinga (site 1) and arboreal restinga (site 2). We used as trap-nests, bamboo canes, large and small straws of cardboard inserted into solid wooden blocks. Five bee species established 193 nests, from which 386 adults emerged. Centris tarsata Smith was the most abundant species. Large straws were signifi cantly more occupied than small straws (χ² = 19.951; df = 1; p < 0.0001). Offspring mortality rate for unknown reasons was signifi cant diff erent between sites, 11% (site 1) and 20% (site 2) (χ² = 4.203; df = 1; p = 0.04). The cavity-nesting bee guild had similar composition in both phytophysiognomies, there was a similar rate of occupation of trap-nests in both sites, as well as dominance of C. tarsata nests. Offspring mortality and parasites attack rates seem to be the more distinctive aspects between the herbaceous shrub and arboreal restinga sampled. Our study indicated that remnant fragments of coastal native habitats may be important nesting sites for the maintenance of bee populations, some of which have been indicated as candidates for management as pollinators of cultivated plants in Brazil.
