Flight activity of stingless bees Tetragonisca angustula in the year. The objective of this experiment was to study the foraging behavior of Stingless bees Tetragonisca angustula throughout the year. The collections of material were made in the experimental area of Meliponicultura Sector, Universidade Federal Rural de Pernambuco, in Recife, PE. Once a month, for twelve months, an assessment was made of the flight activity of stingless bees, by recording the number of bees entering the nest carrying pollen and nectar, from 7:00 a.m. to 5:00 p.m., 10 minutes each time. Significant differences between samples of twelve months (one year) of collection, both for collecting nectar/water as for pollen. To collect nectar, the month that stood out was March 2019, summer (bordering the fall), and least stood out was in July 2018 (winter). The collections most abundant nectar temperatures were between 25.0 and 35.3°C, and relative humidity were between 27.1 and 64.9%. For pollen, ideal temperatures were between 23.7 and 34.4°C. Stingless bee T. angustula was very sensitive to temperature and the onset of external 10 activity to collect nectar occurred with a minimum temperature of 17.8 ° C, and, to pollen, the temperature was even higher, 19.6°C. The relative humidity was not a limiting factor for the foraging behavior of the species. This bee, on average, collected for nectar/water 86.3% and 13.7% by pollen.

The study of plants supplying trophic resources to bees is important for the preservation, management and production of beekeeping and meliponiculture. The objective of this research was to study the biodiversity and forage behavior of bees in coriander inflorescences. This experiment was conducted at the Federal Rural University of Pernambuco, Campus Dois Irmãos, located in Recife, PE. The frequency of visitations and the type (nectar and / or pollen) of bees collected in the coriander inflorescences during the day were evaluated. These data were obtained by counting in the first 10 minutes of each time, between 9:00 a.m. and 5:00 p.m. with three repetitions, during three distinct days. Mainly bees were observed visiting coriander inflorescences being stingless bees Trigona spinipes (35,95%), stingless bees Plebeia sp. (12.21%), Africanized honeybees Apis mellifera (5,78%), Halictidae native bees (3,1%) and stingless bees Frisiomellita varia (0.99%). T. spinipes stingless bees were the most frequent and constant, collecting nectar and pollen. This plant species should be planted near apiaries and meliponaries being an important source of food resources for both Africanized and wild bees in Recife, PE.

(2018) Santos, Érika Millena da Silva; Melo, Hélio Fernandes de; http://lattes.cnpq.br/6890648212766368; http://lattes.cnpq.br/3090807086261837
During Earth's history, the oxygen concentration in the atmosphere oscillated to such an extent that the insect group began to morphologically adapt to the new oxygen concentrations over time. Thus, the most adequate mechanism for the breathing process by this group is the tracheal system, which is composed of a network of internal tubes connected to orifices that connect with the external environment, in order to capture the oxygen present in the atmosphere. Oxygen will be consumed to a greater or lesser amount bythe insects, depending on the intensity of their metabolicactivities. Among the most active insects are bees that constantly need a large intake of oxygen in order to meet their biological needs. The objective of this study was to evaluate the species of bees (Trigona spinipes, Scaptotrigona sp.and Apis mellifera) regarding their tracheal dilatation, comparing them to each other. The bees were captured through active collection, with a total of 150 individuals, 50 individuals of each species. The area of the collection was the surroundings of the Rural Federal University of Pernambuco, Campus Serra Talhada. Subsequently, the individuals were weighed on an analytical scale to obtain the initial mass value of each one. They were then placed in a 60-ml syringe with a valve attached and submerged in a solution containing 1% Triton X-100, in which movements of back and forth was performed in the syringe plunger, so that the liquid could enter in the animal's body and fill its entire tracheal system. The insects were weighed again to obtain the final mass. By weighing the individuals before and after being emerged in the solution, the tracheal dilatation (%) was obtained. Finally, it was observed that the native bees had a greater tracheal dilation compared to ape mellifera, and that this result could be related to a lower respiratory rate in the Meliponini species.

(2025-03-19) Mamede, Luiz Fernando Santos; Dantas, Priscylla Costa; Dueñas Cáceres, Juan Sebastián; http://lattes.cnpq.br/4170454372593251; http://lattes.cnpq.br/6273432811214707; http://lattes.cnpq.br/7691262459335217
Os sistemas agroflorestais (SAFs) destacam-se como estratégias sustentáveis capazes de harmonizar produção agrícola e conservação da biodiversidade, especialmente em biomas Hotspot de biodiversidade como a Mata Atlântica. Este estudo investigou a diversidade de abelhas em um SAF localizado no bioma Mata Atlântica no estado de Pernambuco, utilizando armadilhas cromáticas azuis posicionadas a 1,20 m do solo. O trabalho foi conduzido no Espaço de Práticas Agroflorestais da Universidade Federal Rural de Pernambuco (UFRPE), o qual tem uma área de 660 m² com espécies arbóreas (ex.: pau-ferro, ingá), frutíferas (ex.: mamão, graviola), tubérculos e cultivos de hortaliças. Durante oito semanas (novembro/2024 a janeiro/2025), foram realizadas coletas semanais. Os espécimes coletados foram contados e separados por morfoespécie e identificados até a mínima categoria taxonômica possível. adicionalmente foram calculados alguns parâmetros de diversidade. No total foram avaliados 821 indivíduos, distribuídos em 45 morfoespécies, com dominância da subfamília Halictinae (91,35% dos indivíduos). O índice de Shannon-Wiener (H’ = 1,98) indicou diversidade moderada, típica de ambientes heterogêneos como SAF, enquanto a baixa equitabilidade (J’ = 0,52) refletiu a dominância de poucos táxons, como a morfoespécie 1 Augochlorini (50,6% das capturas). A completude amostral foi estimada em 78,8% (Chao1 = 57,07). A eficiência das armadilhas (0,61 abelhas/armadilha/dia). Os resultados destacam o potencial dos SAFs como refúgios para as abelhas e reforçam a importância de pesquisa para conservação desses insetos, salientando sua importância ecológica e econômica. Os SAFs, aliados a práticas de manejo sustentável, são ferramentas-chave para conciliar produção agrícola e conservação da biodiversidade, aumentando resiliência de comunidades às mudanças climáticas causadas por ações antrópicas e auxiliando na soberania alimentar.

(2022-06-01) Oliveira, Suzykelly Gomes Ferreira de; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/7709182422724009
Bees and pollination activities are extremely relevant processes not only for the agricultural sector, but for humanity in general. The use of pesticides becomes a problem when they exert a destructive influence on those insects. The misuse causes behavioral disorders and bee colony reduction, and a consequence of this problem also becomes an aggravating factor in the economic sector. The most commonly used pesticides are neonicotinoids. Studies on the sublethal effects need to have a higher level of depth, since the effects on bees are observed in long terms and can cause damage at colony levels, as it will be susceptible to contamination by the harmful substances. In this review, information will be collected to explain how pesticides affect bees. It is extremely important to obtain, through these references, answers that show the impacts that these substances cause on bees, allowing an elucidative analysis on the main subject of this question. This document deals with data referring to a literature review on the effects that pesticides have on bees.
Importância das flores da calabura (Muntingia calabura) para manutenção de espécies de abelhas
(2021-12-03) Souza, Gleidson Passos de; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/1891794335885463
Knowing the plants in a specific area, their flowering time and the characteristics of their pollen can help to assess the food supply of bees, in periods of lesser availability of bee pasture. Muntingia calabura, also known as calabura, is native to southern Mexico, the Caribbean, Central, Western and South America, also in southern Peru and Bolivia, the first seedlings were introduced in Brazil in 1962 by the Instituto Agronômico de Campinas ( IAC) in order to recover degraded areas. The main objective of this study was to show the importance of bee species visiting the calabura flowers, raising data on pollen and nectar sources, which are available at certain times of the year. The study was developed at the Native Bee Conservation Nucleus, Sector of Beekeeping and Meliponiculture, Department of Animal Science, Federal Rural University of Pernambuco (UFRPE), Recife-PE, with a duration of twelve months of observation, from August 2018 to August 2019. The bee species were evaluated starting in the first 10 minutes of each time, between 6:00 and 17:00, with three repetitions being carried out over three different days, evaluating the collection habit of each species of floral visitors. For the statistical analysis of the data, the BIOESTAT program was used together with the Casualized Statistical Design (DIC). Tukey's test, at a 5% probability level, was used to compare means. In the observations we saw the presence of several species of insects in the collection of floral resources, however there was a predominance of bees. During the observations, 65% were from Africanized bees Apis Mellifera, (26.09%) from stingless bees Tetragonisca angustula (Jataí), (8.12%) from Trigona spinipes (irapuá) bees. Other bees were also observed, such as Melipona scutellaris (uruçu nordestina) and Pseudaugochlora gramínea, as well as Lepidoptera, Diptera and Vespids, using the flowers as a food resource. We came to the conclusion that this plant species should be part of the local flora and should be planted close to meliponaries and apiaries, being an important source of food resources (nectar and pollen) for Africanized and native bees and helping to conserve other species.
Importância das flores do Cosmos sulphureus para manutenção de diversas espécies de abelhas

Bees have an integral dependence on floral products. In order to meet their dietary needs, they visit several flowers continuously, with the aim of harvesting the pollen that serves as a source of protein and the nectar that serves as a by-product for honey production. Among the visits of the bees to the flowers, occurs the process called pollination, in which happens the deposit of pollen from one flower on the stigma of another. Among the flowers most visited by bees in Brazil, are prominent those belonging to the family Asteraceae, and one of them is a plant called Cosmos sulphureus, popularly known as the yellow Cosmos. This study aimed to evaluate the frequency, profile of visits and the type of bee collection in the flowers of C. sulphureus. The relationship between bees and plants of the cosmos type was observed by counting the frequency of visits and the type of material (nectar and/or pollen) to be collected. The foraging behaviour of different bee species was also assessed. Entirely Casualised Delineation and Tukey testing were used to compare treatment averages. Statistical analyses were processed using BioStat software. Visits to the most frequent bees were between 7:00 and 12:00 a.m. Among the main species of bees that carried out visits to the Cosmos, stood out those of the Halictity family: Pseudaugochloropsis graminea (25.57%) and Augochlora sp. (23,30%); solitary bees Megachile rotundata (23.0%) and, in lesser numbers, bees without sting Remote plebea (7.96%), Trigona spinipes (7.39%) and solitary bees Xylocopa frontalis (2.84%). The Cosmos should be planted near apiaries and meliponaries as a source of food for Africanized and wild bees.
Importância das flores do Miguê (Antigonon leptopus) para a manutenção das abelhas nativas
(2021-06-30) Barbosa, Lizandra do Nascimento; Souza, Darclet Teresinha Malerbo de; http://lattes.cnpq.br/3266223126925865; http://lattes.cnpq.br/7631293942576365
The present work aimed to analyze and register the possible floral visitors of Chain of Love vine (Antigonon leptopus) in their flowering period between September to November 2019. The blooms of the species of A. leptopus located in the vicinity of the meliponiculture sector of the Rural Federal University of Pernambuco, UFRPE, for three non-consecutive days from 7 am to 17: 10 pm. Possible visitors and the type of collection made by them were recorded in the first ten minutes of each time in the period observed. It was found that Trigona spinipes and Apis mellifera, were the main bees to make visits to collect nectar and pollen. The melipona Boca de sapo (Partamona helleri), Iraí (Nannotrigona testaceicones), Tubi (Scaptotrigona tubiba) and Uruçu (Melipona scutelaris) respectively, were also observed performing collection activities during the early periods of the day. The climatic condition significantly impacts the foraging activities of bees, sunny or cloudy days with mild temperatures, result in an increase in collection activities. T. spinipes can exhibit dominance, territorial and aggressive behavior with other species, depending on the availability of food. A. leptopus has a good diversity of floral visitors, and its use is indicated for the feeding and foraging of honeybee species.
Inferência filogenética de Apoidea (Hymenoptera) a partir da análise do grau de homologia do citocromo c por ferramentas de bioinformática
(2022-06-01) Melo, Ericles Charles Da Silva; Buarque, Diego de Souza; http://lattes.cnpq.br/7609652740088882; http://lattes.cnpq.br/4571885030401284
The Apoidea superfamily (Hymenoptera) is home to about 30,000 recorded species and consists of several subgroups of apoid bees and wasps, with different types of habits from kleptoparist to eusociality. The species of this subfamily can be identified by body division (head, mesosoma and metasoma) and by the presence or absence of hair on the body. Due to the great difficulty in establishing molecular markers that can infer the phylogeny of this group, we aimed in this work to verify if cytochrome c, a protein essential to oxidative metabolism and energy production, highly conserved in species, can satisfactorily fulfill this role. The work consisted of two approaches: 1) the search for the primary sequences of cytochrome c of organisms of the Apoidea superfamily available in biological databases (NCBI Protein), for subsequent multiple alignment and obtaining a phylogenetic tree through the MAFFT program; 2) comparison with the phylogenies present in the literature. FASTA sequences were obtained from 15 species, all containing 108 amino acid residues. The cladogram obtained from the proposed alignment shows that the Bombini and Apini tribes seem to form a sister group. The study also showed that the common ancestor that gives rise to the Euglossini tribe also gives rise to the Bombini, Apini and Meliponini tribes, thus demonstrating that Apini and Euglossini can be paraphyletic groups. Despite the few Apoidea cytochrome c sequences available in the NCBI Protein, it was possible to observe that the cladogram seems to go against some proposals in the literature, suggesting that cytochrome c seems to be promising for this purpose. However, this study does not immediately propose a new classification, as it would be necessary to analyze a greater number of primary sequences from different Apoidea species. Therefore, more studies are needed in different groups among the Hymenoptera so that it is possible to use cytochrome c as a possible marker.
Levantamento da fauna apícola em monocultivo de sabiá (Mimosa caesalpiniifolia) em área de Caatinga no Agreste pernambucano
(2021) Silva, Isabela Nascimento; Gonçalves, Maria da Penha Moreira; http://lattes.cnpq.br/0539509819672370; http://lattes.cnpq.br/6582276513482324
Due to the semi-arid climate characteristics, the Caatinga biodiversity presents a rich diversity of plant and animal life. Within this wealth, native bees stand out, which play an important role in the balance of forest ecosystems. Thus, the objective of the present work was to carry out a survey of the apicultural fauna in areas of sable cultivation and native vegetation of Caatinga in the rural region of Pernambuco. The research was carried out at the experimental station of the Instituto Agronomic° de Pernambuco - IPA, municipality of Caruaru, Pernambuco. The study was carried out during the months of December 2020 and January 2021 in two areas of Caatinga equidistant 30 m from each other, one planted with thrush (Mimosa caesalpiniifolia) and the other with native vegetation. In each area, two 10 m x 10 m transects were drawn for the installation of traps. Two models of traps were installed, one with a bottle using scent essences (vanilla and methyl salicylate) and another with yellow Pantraps, in which the attractiveness is based on color. 29 individuals of bees distributed in three genera were catalogued. Of these, two were identified at the genus level (Trigona sp., Bombus sp.) and one at the species level (Apis melifera scutellata). Pantraps did not attract any insect considered to be a bee, regardless of the area or period of collection. A higher frequency of bees was observed in the dry period compared to the rainy period. In the sabia area there was greater visitation by bees (82% of the individuals) and greater preference for visitation after using the methyl salicylate essence (79% of the individuals), however the vanilla essence was efficient in attracting them. It is concluded that the method of collecting bees using scent traps in the Caatinga environment of the Pernambuco agreste proved to be efficient when using vanilla and methyl salicylate essences, the latter being the most effective in attracting these insects. The modifications that occurred in the monoculture of Sabia in the Caatinga environment did not negatively influence the diversity of bees, when compared to the area of native forest in the region, with similar diversity being observed in both areas.
Ocupação de ninhos-armadilha por abelhas e vespas solitárias (Hymenoptera, Aculeata)
(2023-09-22) Silva, Mirella Cruz de Sa e; Oliveira, Mikail Olinda de; http://lattes.cnpq.br/4962593504082966; http://lattes.cnpq.br/9886581010910725
The present study aimed to analyze the occupation and acceptance of trap nests by solitary bees and wasps (Hymenoptera, Aculeata), as well as identify possible nesting preferences. The Experiment was carried out on the campus of the Federal Rural University of Pernambuco, Academic Unit of Serra Talhada, during the months of November 2022 to July 2023. Observations were carried out weekly, during eight months of sampling. To carry out the sampling, four cylindrical wooden blocks (CB) (n=100) were used, with cavities with diameters of 6 and 8mm. The CBs were made with high-density native wood (Astronium urundeuva (M.Allemão) Engl.), untreated. The results showed that 58 nests were founded during the study period. The nesting activity of solitary bees was higher than that of solitary wasps throughout the study period. There was a preference for occupying cavities with 6mm in diameter, ensured by a significant statistical difference (p<0.0001), when compared to occupying cavities with 8mm in diameter. Three types of materials used to close the end of the nests were identified, with clay being the least frequent material with 13.79% of the total nests, while resin was the second most used with 39.66%, followed by the aggregate of mixtures with resin, with the highest proportion 46.55%. The results indicated that the species that nested in the study area prefer narrower cavities. Furthermore, the present study highlights the uncertainty of the influence of the environment on the nesting activity of solitary species, and it is ideal to adopt caution when choosing the location for installing trap nests.

(2019) Sá, Marileide de Souza; Lima, Marilene Maria de; http://lattes.cnpq.br/9135077184593725; http://lattes.cnpq.br/3415518545368497
The aim of this study was verifying the prevalence,infestation taxa and period of occurrence of parasitoses in Apis mellifera L. 1758 at tree municipalities of Pernambuco, Northeastern, Brazil. The samples were carried out in apiaries of Garanhuns, Manarí and Serra Talhada, from April / 2018 to February / 2019. In Manarí, 20 samples were collected (10 in wooden boxes and 10 in cement boxes, to analyze quantitative interference and occurrence according to the hive material) and 10 boxes were migratory, totaling 50 samples per collect. The bees were conditioned in 150 ml plastic bottles with 50 ml of 96 ° GL alcohol and analyzed at UFRPE / UAST Microscopy II laboratory. After 48 hours the mites were counted and the analysis of the occurrence of Nosema spp. spores. According our results, we identified the presence of the parasites in 100% of all the apiaries visited. The highest occurrence was on winter where we found 1,716 mites, representing 51.84% of the total.. Regarding the presence of Nosema spp. all the apiaries had an occurrence of the parasite, however, the highest occurrence in the apiaries was in the rainfall period, with the Garanhuns, Manari (wood and migratory) colonies being the most infested. In relation to the meteorological factors, in the municipality of Serra Talhada the Varroa destructor mite shows that it undergoes the influence of the three factors analyzed Humidity (%), Temperature (°C) and Precipitation (mm), whereas Nosema spp. is influenced by humidity and precipitation. In the municipality of Manari, Nosema spp. has a greater influence of moisture and precipitation in the fall period, whereas the Varroa destructor when precipitation occurs in autumn. In Garanhuns, the period of greatest precipitation and high humidity in the region occurred in autumn, the period of highest incidence of Nosema spp., While mites, although occurring throughout the collection period, during the period when the highest temperatures occurred in the region were when they occurred higher rates of Varroa destructor. Therefore, it is necessary to monitor the infestation rate, which factors would be associated with the prevalence in the regions, orientation to beekeepers as to how to identify and notify the government that there is a survey of the bee health situation in the municipality and in the state, thinking about the preservation of bee species and biodiversity.

(1994) Barbosa, Severino Benone Paes; Martinho, Mauro Roberto
Analisaram-se dados de 72 amostras de geleia real colhidas durante o mês de junho de 1986, em uma coméia orfanada com cerca de 25.000 abelhas africanizadas, no apiário da Universidade Federal de Viçosa. A produção média não ajustada de geleia real por cúpula foi de 257,72 mg ± 115,04. O ensaio experimental constou de seis tratamentos, de acordo com o tempo de coleta da geleia real (24, 32, 48, 64, 72 e 80 h), após transferência da larva. A análise de variância mostrou diferença significativa entre tratamentos (P<0,01) e para desdobramento polinomial linear e quadrático (P<0,01). Maiores produções de geleia real foram obtidas entre 48 e 64 h após a transferência da larva, com pico máximo de produção (356,56 mg) em torno de 57 h. Os coeficientes de regressão linear e quadrático foram 0,03212730891 e -0,0002813935, respectivamente.

Bees have a role in nature of fundamental importance in the balance of an ecosystem, being directly responsible for the pollination of plants, certain types of food that are only viable due to this arduous task, bees are present around the world and have thousands of different species, including those with stingers and those without stingers. Meliponiculture, which is the production of native stingless bees, has been increasingly developed with the growing search for natural and sustainable products, created in a rational way, and this is something that has been developed for many generations by indigenous peoples. The meliponiculture sector, located in the Zootechnics Department at UFRPE in Recife, comes through the efforts of its teaching, research and extension activities, to emphasize and propagate the importance of preserving these insects so important for the functioning of the production chain and consequently of life human. The different species that are found in the sector are native to the region of the Zona da Mata and coast of Pernambuco, where the department is close. The sector seeks to preserve these colonies for the dissemination of knowledge with society. The species found in the structure of the meliponary were cataloged and the development of these colonies was monitored, as well as artificial feeding was offered to those colonies that had a deficit of food stored in their boxes.
