Under the radar: the kleptoparasite Pseudohypocera kerteszi evades meliponine bee defense without cuticular hydrocarbon mimicry or camouflage Catarina Silva Correia, Éricles Charles da Silva Melo, Daniela Maria do Amaral Ferraz Navarro, Airton Torres Carvalho, Artur Campos Dália Maia Apidologie, 2026 Pseudohypocera kerteszi is a kleptoparasitic scuttle fly that invades meliponine bee hives, exploiting colony pollen reserves to provision its larvae. Such invasions can precipitate colony collapse, posing a significant threat to meliponiculture in Central and South America. Notably, the flies enter colonies with minimal resistance from typically aggressive guard bees, prompting questions about potential chemosensory or behavioral manipulation. To explore this, we compared the cuticular hydrocarbon (CHC) profiles of P. kerteszi with those of three co-managed meliponine bee species— Melipona scutellaris , Nannotrigona minuta , and Scaptotrigona tubiba —and conducted behavioral assays in controlled arenas and at nest entrances, using S. tubiba as a model species. The CHC profile of P. kerteszi comprises 50 compounds—including n -alkanes, unsaturated hydrocarbons, methyl-branched alkanes, and fatty acyls—with the unique presence of 8,18-heptacosadiene and 10-dotriacontene. In contrast, workers of M. scutellaris , N. minuta , and S. tubiba exhibit profiles dominated by odd-chain alkanes and alkenes, with little or no contribution from alkadienes or methyl-branched alkanes. Bioassays revealed that while S. tubiba guard bees aggressively reject non-nestmates, they tolerate adult P. kerteszi . These findings provide strong evidence against chemical mimicry, camouflage, or insignificance as primary drivers of host acceptance. Instead, the data are consistent with the hypothesis that P. kerteszi utilizes alternative mechanisms, such as physical evasion facilitated by its small size and maneuverability, to prevent the initiation of a full defensive response. This study provides the first chemical characterization of P. kerteszi and narrows the scope of potential evasion strategies, guiding future research on this kleptoparasitic system.
Diet of the Dark-billed Cuckoo Coccyzus melacoryphus during the reproductive period in the semi-arid region of north-eastern Brazil Juan Lima, Hugneide Souza, Airton Carvalho, Cecilia Calabuig Bird Study, 2025 Capsule The migratory Dark-billed Cuckoo breeds in the Brazilian semi-arid Caatinga biome during the rainy season, where its diet predominantly comprises insects from the orders Lepidoptera and Orthoptera, reflecting intermediate trophic niche diversity.Aims To analyse the stomach contents of Dark-billed Cuckoo specimens collected opportunistically after fatal collisions, identifying dietary components, trophic niche breadth and patterns related to prey selection and seasonal resource availability.Methods Stomach contents of 72 Dark-billed Cuckoo specimens collected from four areas in north-eastern Brazil were analysed. Prey items were identified and quantified to determine taxonomic composition, frequency of occurrence, percentage of occurrence, biomass contribution and trophic niche amplitude. Morphometric measurements of the birds were compared with prey size to assess potential relationships.Results A total of 434 prey items, distributed among nine higher taxa, were identified, with Lepidoptera and Orthoptera predominating. Orthopterans represented the majority of the biomass ingested, while lepidopteran larvae were consumed most frequently. The standardized trophic niche breadth (Ba = 0.582) indicated intermediate resource diversity. No systematic relationship was found between prey size and bird morphology. Dietary patterns were consistent across study areas and aligned with previous findings for the species’ feeding habits.Conclusion The seasonal presence of the Dark-billed Cuckoo in the Caatinga is closely linked to resource availability during the rainy season, emphasizing the influence of abiotic factors on its migration and foraging strategies. The findings highlight the species’ reliance on energetically rewarding prey, such as Orthoptera and Lepidoptera, and provide insights into its ecological role within the Caatinga biome.
Antibacterial and Toxic Activity of Geopropolis Extracts from Melipona subnitida (Ducke, 1910) (Hymenoptera: Apidae) and Scaptotrigona depilis (Moure, 1942) (Hymenoptera: Apidae) Danilo Costa dos Santos, Nair Silva Macêdo, Zildene de Sousa Silveira, Raimundo Luiz Silva Pereira, Isaac Moura Araújo, Ana Carolina Justino Araújo, Sheila Alves Gonçalves, Marcos da Silveira Regueira Neto, Valdir de Queiroz Balbino, Airton Torres de Carvalho, Bruno Oliveira de Veras, Francisco Assis Bezerra da Cunha, Henrique Douglas Melo Coutinho, Samuel Vieira Brito Chemistry and Biodiversity, 2023 Bacteria are associated with many infections that affect humans and present antibiotic resistance mechanisms, causing problems in health organisations and increased mortality rates. Therefore, it is necessary to find new antibacterial agents that can be used in the treatment of these microorganisms. Geopropolis is a natural product from stingless bees, formed by a mixture of plant resins, salivary secretions, wax and soil particles, the chemical composition of this natural product is diverse. Thus, this study aimed to evaluate antibacterial activity, antibiotic modulation and the toxicity of geopropolis extracts from the stingless bees, Melipona subnitida (Ducke, 1910) and Scaptotrigona depilis (Moure, 1942) against standard and multi‐resistant Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa bacteria. Geopropolis samples were collected in a meliponary located in Camaragibe, Pernambuco, Brazil. To determine the Minimum Inhibitory Concentration (MIC) and antibiotic modulation we performed broth microdilution tests. Mortality tests were used to verify extract toxicity in the model Drosophila melanogaster. The microbiological tests showing that the M. subnitida extracts had better inhibitory effects compared to S. depilis, presenting direct antibacterial activity against standard and multi‐resistant strains. The extracts potentialized antibiotic effects, suggesting possible synergy and did not present toxicity in the model used. The information obtained in this study highlights extracts as promising antibacterial agents and is the first study to evaluate bacterial activity in these extracts, in addition to verifying their modulating effects and determining toxicity in the model used.
Nest density, spatial distribution, and bionomy of Trigona spinipes (Apidae: Meliponini) Edigleidson Fideles Valadares, Airton Torres Carvalho, Celso Feitosa Martins Journal of Apicultural Research, 2023 Trigona spinipes is a generalist species of stingless bee that is dominant in many pollination networks and has a wide distribution in the tropics and subtropics of the Neotropics. This eusocial species builds exposed aerial nests in tree branches. Although some studies have been carried out on nest density, there are surprisingly few studies on its bionomy, and especially on the population size of the colonies. To survey the density and spatial patterns of nests of this stingless bee, three sites within the Northeast region in Brazil were studied, which ranged from urban to rural to forest habitats. A high density of nests was found in rural and urban sites, with 0.6 nests/ha and 0.4 nests/ha, respectively. In comparison, a lower density was found in the forest site, with 0.1 nests/ha in the edge and 0.03 nests/ha in the interior. Thus, the highest density of nests occurred in open areas. In the urban site, the nests showed a uniform distribution, while the distribution was aggregated in the rural site. The majority of nests were oriented so that the entrance faced the opposite direction to prevailing winds. Several aspects of the bionomy of 22 nests were sampled. The mean estimated total population size of colonies (immatures plus imagoes) was 38,813 (range 25,581–53,083) individuals, with 13,202 adults. Our results confirm that this species produces some of the largest colonies within the stingless bees, although lower than previously mentioned, emphasizing its importance in ecosystems of open neotropical areas.
Species redescription and nest architecture of Plebeia flavocincta (Hymenoptera: Apidae: Meliponini) Ulysses Madureira Maia, Rafael Cabral Borges, José Eustáquio dos Santos-Júnior, Victor Hugo Pedraça Dias, Airton Torres Carvalho, Vera Lucia Imperatriz-Fonseca, Guilherme Corrêa de Oliveira, Tereza Cristina Giannini Apidologie, 2022 Bees are important insects both environmentally and economically. Despite this, most bee species are poorly characterized regarding their morphology and nesting habits, which are relevant characteristics for planning management and conservation. Plebeia flavocincta is a stingless bee species that occurs in the Northeast region of Brazil and there is little knowledge about its morphology and nesting biology. Here, we morphologically characterize Plebeia flavocincta workers from 54 colonies and use seven colonies to describe the structure of the species’ nest. All nests were found in seasonally dry forest areas in different substrates, namely, hollow of native trees, wall, post, and wooden boxes. The structure of the species’ nest was detailed in terms of the number, shape, and area of the combs; brood cell size; size of food pots; nest size; and honey volume. Plebeia flavocincta is found in both natural and urban environments. The structure of the nest of Plebeia flavocincta is similar to that found in other species of the same genus. This is the first nest diagnosis study of the species. In addition, by establishing morphological data to recognize Plebeia flavocincta, this study provides useful information for management and conservation plans for the species.
Evidence for morphological and genetic structuring of Plebeia flavocincta (Apidae: Meliponini) populations in Northeast Brazil Ulysses Madureira Maia, José Eustáquio dos Santos Júnior, Michele Molina, Juliana Stephanie Galaschi-Teixeira, Airton Torres Carvalho, Leonardo de Sousa Miranda, Vera Lucia Imperatriz-Fonseca, Guilherme Oliveira, Tereza Cristina Giannini Frontiers in Ecology and Evolution, 2022 Tropical dry forests are increasingly threatened by human activities. In Northeast Brazil, the Caatinga, an area of tropical dry forests surrounded by wetlands, is considered globally unique among these habitats. In this region, the stingless beePlebeia flavocinctais found in a variety of environmental, ecological, and demographic conditions. We aimed to characterizeP.flavocinctapopulations within its natural range through wing geometric morphometrics and mitochondrial DNA (mtDNA) analyses. The characterization of population variability can clarify whether the species is morphologically and genetically diverse and whether populations are morphologically and genetically structured. We analyzed 673 samples by wing morphometry and 75 by cytochrome-b assays. Our results revealedP.flavocinctais genetically and morphologically diverse and populations are morphologically and genetically structured. Despite the differentiation between the two most morphologically distant populations, we verified a large overlap of morphological variation between all populations. The genetic analysis showed that the haplotypes were geographically structured into six clusters, four of which were located in coastal areas, and the remaining two in the drier inland region. The characterization ofP.flavocinctapopulations is an important step toward decision-making in programs for the protection, management, and sustainable use of this stingless bee in local breeding efforts.
Longitudinal survey reveals delayed effects of low gene expression on stingless bee colony health Lílian Caesar, Anelise Martins Correa Lopes, Jefferson Nunes Radaeski, Soraia Girardi Bauermann, Enéas Ricardo Konzen, Jean-François Pombert, Aroni Sattler, Betina Blochtein, Airton Torres Carvalho, Karen Luisa Haag Journal of Apicultural Research, 2022 Bee populations are declining globally due to different environmental stressors, such as pathogens, malnutrition, and agrochemicals. Brazil is the home of hundreds of stingless bee species, some of them now considered endangered, though very little is known about the impact of disease on native bees. In Southern Brazil the endangered stingless bee Melipona quadrifasciata is affected by an annual syndrome that causes sudden death of workers, eventually leading colonies to collapse. Although novel viruses were found in foragers from diseased colonies, none has been consistently implicated in the outbreak. Here we conducted an integrative longitudinal survey on M. quadrifasciata managed colonies, measuring individual- and colony-level traits, to identify the causes behind the syndrome. We found that key genes related to xenobiotic metabolization, nutrition and immune responses are downregulated in foragers from colonies that became diseased two months later. The period that preceded the outbreak was also marked by pronounced forager weight loss as well as behavioural changes. Our findings reveal the syndrome may result from the stingless bee failure to respond to sublethal stressors and disruption of colony dynamics. These results support the proposition that worldwide bee mortality is influenced by a combination of diverse sublethal factors, and increase awareness of the long-term effects of genetic diversity erosion in stingless bee species, which can be enhancing their vulnerability to environmental stressors.
Climate-induced distribution dynamics of Plebeia flavocincta, a stingless bee from Brazilian tropical dry forests Ulysses Madureira Maia, Leonardo de Sousa Miranda, Airton Torres Carvalho, Vera Lucia Imperatriz‐Fonseca, Guilherme Corrêa Oliveira, Tereza Cristina Giannini Ecology and Evolution, 2020 AIM: and to evaluate the influence of climate on the dynamics of suitable habitat availability in the past and in the future. LOCATION: Northeast region of Brazil and dry forest areas. METHODS: The habitat suitability modeling was based on two algorithms, two global circulation models, and six different scenarios. We used this tool to estimate the areas of occurrence in the past (Last Interglacial and Last Glacial Maximum), in the present, and in the future (years 2050 and 2070). RESULTS: had great dynamics in the availability of suitable habitats with periods of retraction and expansion of these areas in the past. Our results suggest that this taxon may benefit in terms of climate suitability gain in Northeast Brazil in the future. In addition, we identified high-altitude areas and the eastern coast as climatically stable. CONCLUSION: The information provided can be used by decision makers to support actions toward protecting and sustainably managing this taxon. Protection measures for this taxon are particularly important because this insect contributes to the local flora and, although our results indicate that the climate may favor this taxon, other factors can negatively affect it, such as high levels of habitat loss due to anthropogenic activities.
