“…The availability of floral resources is one of the factors that can influence the nesting of bees that use this resource (Scheper et al, 2015, Dainese et al, 2018. In the particular case of oil-collecting bees, studies of nesting activity in bee species of the genus Centris in trap nests have shown that they do not nest in the absence of this resource, with its abundance seeming to regulate the nesting rate (Magalhães & Freitas, 2013;Lourenço et al, 2019). Byrsonima sericea, in turn, appears to be a good source of this floral resource for these bees, since Lourenço et al, 2019, working in the same area as the present research, saw C. analis nesting in trap nests throughout all six months of the study, with the peak of nest construction and brood production coinciding with the start of flowering in this plant species.…”

“…However, oil-collecting bees are neither bred rationally nor used for agricultural pollination. Although studies of some species of the genus Centris have shown that they are abundant and may even be managed in trap nests in areas of nance and acerola (Pereira & Freitas, 2002;Magalhães & Freitas, 2013), the dependence of these bees on floral oils for bulding their nests and feeding their brood has been seen as a limiting factor for their use on a larger scale and with other agricultural crops (Freitas & Pereira, 2004;Lourenço, et al, 2019). Therefore, knowledge of the chemical composition of floral oils may be important in order to get around this obstacle.…”

“…Studies aimed at knowledge of the chemical constituents present in floral oils are fundamental for a better understanding of how the plant-pollinator interactions work in this highly specialised system, as well as for generating information that may serve as a basis for the development of technologies which could aid in the conservation of both animal and plant species, in addition to facilitating the management and permanence of these bees in agricultural crops that benefit from their pollination services. Therefore, the aim of the present study was to analyse the chemical profile and to identify the main constituents of the floral oil of Byrsonima sericea, a species abundant in the Northeast of Brazil and widely used by oil-collecting bees (Rosa et al, 2007;Lourenço et al, 2019).…”

The recent decline in population of generalist bees such as those of the genera Apis and Bombus has shown the need to breed and manage a larger number of bee species. Among the species with potential use for agricultural pollination in the Neotropics, a peculiar small group has specialised in collecting floral oil. Therefore, the aim of this study was to analyse the chemical profile and to identify the main constituents of the floral oil of the nance (Byrsonima sericea), an abundant species in the Northeast of Brazil and widely used by oil-collecting bees. A sample of 400 flowers of the nance were collected between October 2017 and January 2018. The samples were derivatised (MSTFA) and analysed by gas chromatography-mass spectrometry in a Model 7890B GC Gas Chromatograph System coupled to a Model 5977A MSD mass spectrometer. The compounds were separated using an HP-5ms capillary column and identified by comparing the mass spectra with the National Institute of Standards and Technology (NIST) database, and by comparison of the retention indices (RI). From the chromatographic analysis, it was possible to identify 23 constituents, especially fatty acids and carboxylic acids. The results indicate the presence of tricosanoic acid, palmitic acid and heneicosanoic acid as the main constituents of the oil under study. There is still a need for studies that would better explain the relationship of these constituents with the bees that use the oil.

“…33448/rsd-v9i10.8880 2002). Therefore, studies on the breeding of these bees have been intensified, mainly with species of the genus Centris that nest in pre-existing cavities because this behavior allowed the use of trap nests and the study of the bees' behavior and biology (Jesus & Garófalo, 2000;Lourenço, Silva, Meneses, & Freitas, 2019). The use of these nests made possible, for example, to study Centris analis nesting and reproductive behavior and to identify this species as a potential pollinator to be managed in acerola crops (Magalhães & Freitas, 2013;Oliveira & Schlindwein, 2009;Vilhena and Augusto, 2007).…”

This study tested three types of Solid-Phase Microextraction fibers in developing a method to extract volatile organic compounds present in the diet of immature Centris analis. Samples were placed in glass vials with metal lids and added with 3g NaCl and 8 ml deionized water. Extraction and characterization were carried out using a Headspace – Solid Phase Microextraction (HS-SPME) with Gas Chromatography – Mass Spectrometry, and the three types of fibers were polydimethylsiloxane (PDMS), divinylbenzene/ carboxen/ polydimethylsiloxane (DVB/CAR/PDMS) and carboxen/ polydimethylsiloxane (CAR/PDMS). Each type of fiber was exposed to volatiles for 30 min and analyzed in a chromatograph Agilent GC-MS equipped with a quadrupole detector (MSD 5977A), containing a HP-5MS (30 m x 0.25 mm x 0.25 µm) column and Helium as the carrier gas (1 ml.min-1). The CAR / PDMS fiber favored the extraction of volatile compounds to semi-volatile compounds, followed by DVB / CAR / PDMS, while PDMS presented a lower number of extracted compounds, which can be attributed to its apolar nature. The volatile compounds identified in the diet included alcohols, aldehydes, esters, ketones, and terpenes. The SPME technique has proven effective in the extraction of volatile organic compounds from immature of Centris analis diet, being the CAR/PDMS the most suitable fiber for this.

Pollen Niche from Tetrapedia diversipes Klug (Hymenoptera: Apidae: Tetrapediini) in a Brazilian Semi-deciduous Lowland Forest

Tetrapedia diversipes Klug (Apidae) is a solitary bee with wide geographical distribution. Females of this species usually nest in pre-existing cavities and although their biology is relatively well known, studies on their trophic niche are still scarce. Thus, the present study aimed to identify the plant species used in the diet of immature T. diversipes through the analysis of residual pollen material. The nests used in the study were obtained through the use of trap nests during the period between December 2014 and October 2015, distributed in an area of coastal forest in northeastern Brazil. For the study of the trophic niche, samples of post-emergency residue (feces) from cells of offspring of males (n = 31) and females (n = 66) of T. diversipes were analyzed. In total, 29 pollen types were identified in the feeding of T. diversipes, being of the pollen types identified, only seven were not used by both sexes. Although a significant difference was found in the amplitude in the trophic niche between the sexes, there was a high overlap for Horn-Morisita index (CH = 0.989), with no significant difference being found in the frequency distribution of male and female food items (D = 0.214; p = 0.341). In this study we concluded that the diet of T. diversipes in coastal forest is polyletic, similarly to the pattern found in other studies of pollen resources in different vegetation in Brazil, with a predominance of pollen from the families Euphorbiaceae, Asteraceae and Onagraceae.
