AbstractTetragonisca angustula is a very important stingless bees species. This study aimed to report the resin gathering behaviour of this species of a possible new resin source: Schizolobium parahyba. Evaluations of temperature, number of bees in gathering activity, time and season were used to characterize bee’s behaviour. Resin gathering activities were concentered between 10 and 14 hours, with a moderate linear positive correlation index with the temperature. No bee activity was observed when temperatures were below 16.69°C. Gathering suffered extreme reduction during winter and greater activity in summer. Bees exploration were concentered on the younger leafs and apical portion of S. parahyba. Older leafs were mainly ignored, and gradually the exploring activity was constantly migrating to most young parts, while apical exploration was consistent all the studied period.

Phylogenomic Analyses

Kluyveromyces osmophilus, a single-strain species isolated from Mozambique sugar, has been treated a synonym of Zygosaccharomyces mellis. Analyses of D1/D2 LSU rRNA gene sequences confirmed that the species belongs to the genus Zygosaccharomyces but showed it to be distinct from strains of Z. mellis. During studies of yeasts associated with stingless bees in Brazil, nine additional isolates of the species were obtained from unripe and ripe honey and pollen of Scaptotrigona cfr. bipunctata, as well as ripe honey of Tetragonisca angustula. The D1/D2 sequences of the Brazilian isolates were identical to those of the type strain of K. osmophilus CBS 5499 (=ATCC 22027), indicating that they represent the same species. Phylogenomic analyses using 4038 orthologous genes support the reinstatement of K. osmophilus as a member of the genus Zygosaccharomyces. We, therefore, propose the name Zygosaccharomyces osmophilus comb. nov. (lectotype ATCC 22027; MycoBank no. MB 833739).

The Lacandon Maya were settled in the Lacandon forest since the 17th century; their experience and knowledge allow them to know and manage different natural elements, like the Native Stingless Bees (nsb). The present research registered the species of nsb and the differentiated knowledge about them in Nahá, Chiapas. From 2015 to 2018, through work with key collaborators and entomological collections, the species of NSB identified by the local population of the Flora and Fauna Protection Area of Nahá (ffpan) were determined. Later a questionnaire was applied to 68 heads of family, all males, to estimate the level of knowledge they have and the uses they give to the native stingless bees, according to age ranges. A total of 15 species of native bees were registered, of which honey is obtained mainly from four: Tetragonisca angustula (Ajyus), Scaura argyrea (K’amas kap’), Plebeia frontalis (Ak chip kap) y Melipona solani (Jach K’ojo’). We registered a differentiated knowledge of the heads of family in Nahá about the 15 species of nsb based on their behavior, morphology and the places where they live. The general tendency is the loss of knowledge, and it is accentuated among the young people. The causes are related to the weakening of the transmission’s mechanisms of knowledge, the decrease of the recollection activities and the absence of management of colonies in their homegardens, as well as the arrival of products that substitute honey and wax, offered at lower prices.

Resumo. No presente estudo realizou-se um levantamento de ninhos de abelhas Meliponini na Estação Ecológica de Água Limpa (EEAL), no município de Cataguases, Minas Gerais. Foram encontrados 21 ninhos pertencentes a nove espécies: Friesella schrottkyi (Friese), Melipona bicolor Lepeletier, Plebeia sp. 1, Plebeia sp. 2, Tetragona clavipes (Fabricius), Tetragona quadrangula (Fabricius), Tetragonisca angustula (Latreille), Trigona hyalinata (Lepeletier), Trigona spinipes (Fabricius). Vinte dos 21 ninhos foram encontrados em substrato arbóreo. A fauna de Meliponini observada na EEAL é representada por um baixo número de espécies. Embora a vegetação local tenha potencial para oferecer substratos para nidificação e recursos florais, a baixa riqueza de espécies pode estar relacionada com o fato da EEAL ser um remanescente florestal isolado. Stingless Bees of the Estação Ecológica de Água Limpa, Cataguases-MG, Brazil Abstract. This study carried out a survey of nests of stingless bees present in the Estação Ecológica de Água Limpa (EEAL) in the municipality of Cataguases, Minas Gerais. We found twenty-one nests belonging to nine species: Friesella schrottkyi (Friese), Melipona bicolor Lepeletier, Plebeia sp. 1, Plebeia sp. 2, Tetragona clavipes (Fabricius), Tetragona quadrangula (Fabricius), Tetragonisca angustula (Latreille), Trigona hyalinata (Lepeletier), Trigona spinipes (Fabricius). Twenty of the 21 nests were found in arboreal substrate. The fauna of stingless bees observed in EEAL is represented by a low number of species. Although the local vegetation has the potential to provide substrates for nesting and floral resources, the low species richness may be related to the fact that the EEAL is an isolated forest remnant.

Stingless bees (Hymenoptera: Apidae, Meliponini) have crucial roles in the ecosystem, offering pollination service and contributing to genetic diversity of species, and also providing honey and wax to humankind. Tetragonisca angustula and Scaptotrigona xanthotricha are species that have been used since ancient times for beekeeping. Currently these and other species have been exposed to agronomic practices, among which the use of synthetic pesticides used for crop protection stands out. The aim of this study was to evaluate the toxicity of the insecticides thiamethoxam and fipronil, which are used in agriculture in several countries in the tropical and subtropical belt in order to establish the risk that these products represent to the survival of these two species. The oral and topical LD50 was obtained by Probit analysis. Comparisons with the LD50s of other stingless bees and Apis mellifera were realized. Although further studies are required to calculate the real risk of the two compounds, the results showed an evident susceptibility of both species. We concluded that it is essential to use tools and practices that reduce the risk, and perform toxicological evaluations of new and existing pesticides on stingless bees.

New Hypothesis

Many Stingless Bees (Hymenoptera: Meliponini) like Tetragonisca angustula collect resin to defend their nests against intruders like ants or Robber Bees. Small portions of resin are attached to intruders bodies and extremities causing their immobilization. It has been observed that resin is removed easily from the bee's mandible but adheres strongly to the intruder's cuticle. We tested the hypothesis that resin sticks lesser to the mandibles of Stingless Bees than to the surface of intruders due to special surface structures or adhesive properties of these structures. The surface structures of the mandible of T. angustula and the trochanter of Camponotus sericeiventris were studied by scanning electron microscopy. To measure adhesion properties, selected surfaces were fixed on a fine glass pin and withdrawn from a glass tip covered with resin. The deformation of the glass pin indicates adhesion forces operating between the resin and the selective surface. The absolute value of the forces is computed from the glass pin's stiffness. It has been shown that resin sticks more to the smooth mandible of the bee than to the structured trochanter of the ant. A new hypothesis to be tested says that the bees might lubricate their mandibles with nectar or honey to reduce the resin's adhesion temporarily.

Due to the current practice of intensive pesticide use in Brazil on crops with flowers that are attractive to bees, biological information about Brazilian native bees is required in order for public authorities that are responsible for environmental safety to use them for calculations of risk assessments. Thus, the present study aimed to obtain biological data on stingless bees: Melipona scutellaris, Scaptotrigiona postica and Tetragonisca angustula. The food consumed by larvae and by adults and the mass of forager workers were obtained. The results provide essential inputs for the risk assessment of stingless bee exposure to pesticides., combined with information about the concentrations of these substances in crops with flowers that are attractive to bees, may be used in risk calculations.

A urbanização tem causado a fragmentação de vários ambientes naturais, levando à perda de muitos processos ecológicos como a polinização, realizada principalmente por abelhas, em especial as espécies de Meliponini, que tem reduzido drasticamente as suas populações devido à perda de habitat pela expansão urbana. O objetivo deste estudo foi realizar um levantamento das espécies de abelhas sem ferrão em áreas urbanas do município de Ubá - MG, Brasil, relacionar a riqueza e abundância das espécies encontradas com a taxa de ocupação das variáveis estruturais da paisagem das áreas urbana e relacionar a presença das espécies obtidos com estas variáveis. Foram encontrados 28 ninhos pertencentes a quatro espécies, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) e Friesella schrottkyi (Friese). Não houve relação significativa entre a riqueza e abundância de Meliponini e variáveis estruturais de vegetação analisadas, possivelmente devido a valores baixos no número de ninhos e espécies encontrados. Somente T. spinipes se mostrou relacionada com a presença de vegetação. Os resultados mostram que a comunidade Meliponini é composta por espécies generalistas capazes de utilizar cavidades artificiais e plantas ornamentais como uma fonte alternativa de recursos, comuns em áreas urbanas. Os resultados obtidos neste estudo servem de alerta para atuais condições dos remanescentes vegetais em áreas urbanas na cidade de Ubá, além de também poderem ser usados como material de apoio na tomada de decisão sobre projetos de conservação e recuperação de áreas degradadas, tendo como foco sobre as abelhas e sua importância para a sustentabilidade destes ecossistemas.Where the most Adapted Remain: Stingless Bees Community (Hymenoptera: Apidae, Meliponini) in Urban Areas of the City of Uba, Minas Gerais, Brazil Abstract. The urbanization has caused the fragmentation of various natural environments, taking to loss of many ecological processes in which includes pollination, realized mainly by bees, in special Meliponini species, which has drastically reduced their populations due to loss of habitat for urban expansion. The aim of this study was to survey the species of stingless bees in urban areas of the municipality of Ubá - MG, Brazil, relate the richness and abundance of species found with the percentage of occupation of the structural variables of the urban landscape and relate the presence of the species obtained with these variables. Were found 28 nests belonging to four species, Tetragonisca angustula (Latreille), Trigona spinipes (Fabricius), Nannotrigona testaceicornis (Lepeletier) and Friesella schrottkyi (Friese). There was no significant relationship between richness and abundance of Meliponini and structural variables of vegetation, possibly due to low values in the number of nests and species obtained. Only T. spinipes showed related to the presence of vegetation. The results show that the Meliponini community is composed by generalist species able to use artificial cavities and ornamental plants as an alternative source of resources, common in urban areas. The results obtained in this study is a warning to current conditions of the plant remaining in urban areas in the city of Ubá, besides may also be used as support in taking-decision on projects for the conservation and recovery of degraded areas, focusing on bees and their importance to the sustainability of these ecosystems.
