Associação entre fungos e abelhas-sem-ferrão do semiárido de Pernambuco
(2021-06-25) Silva, Aparecida Clébia da; Carvalho, Airton Torres; http://lattes.cnpq.br/5995654016063333; http://lattes.cnpq.br/3574387196330564
Throughout the evolution of species, insects and fungi have developed important mutualistic interactions, in which both benefit. An interesting example is the bee of the genus Scaptotrigona spp. (Hymenoptera: Apidae, Meliponini), in which a species of fungus Zygosaccharomycessp. develop and produce important metabolites for the growth of immatures, being essential for the insect to complete its life cycle. In this context, the objective was to investigate the presence of filamentous fungi, associated with larval food, in brood cells with larvae at different stages of development in colonies of Scaptotrigona sp. tubiba group, in Caatinga areas of the state of Pernambuco. The collections were carried out in five colonies in 10 brood cells, being numbered from 1 to 10, in which 1 to 5 were collected in cells with developing larvae, from 6 to 7 only with larval food and egg and from 8 to 10 developed larvae. The samples were solubilized in sterile water and seeded on three culture media for isolation Sabouraud Agar (SAB), Potato Dextrose Agar (PDA) and Potato Dextrose Agar with an additional 15% of glucose (15% PDA). After five days of incubation at 28 ºC, 19 isolates were selected based on morphotypes. Amongst these, 3 were identified at the genus level, being a Fusarium, a Cladosporium and an Arcopilus, which was submitted to macro and micromorphological characterization for presenting characteristics similar to a species described in the literature. Subsequently, the growth capacity of Arcopilus sp. in four different conditions: pure larval feed, larval feed plus distilled water (1:1; v/v), Sabouraud broth and distilled water plus 1% glucose in wells of ELIZA plates. The greatest growth was observed in wells that were seeded with larval feed diluted in distilled water. The presence of Monascus sp. in larval food samples of Scaptotrigona sp. studied. The other isolates were stored for later identification of the species and it is expected that these fungi may actually be essential in the bee nests of this species.
Meliponini do estado de Pernambuco, Brasil

Meliponini is a tribe of eussocial bees popularly known as stingless bees. This group is recognized for its economic value in the production of honey and other honey products such as wax, pollen and geopropolis. However, it is in the pollination service that these bees stand out. However, it is in the pollination service that these bees stand out. This activity, associated with the ease and practicality of its management, represents an important tool to optimize agricultural productivity and the maintenance of ecosystems. Due to the great demand of the market, there is a need to expand the rational breeding of these animals (meliponiculture), and for this it is necessary to formulate a regulation that guarantees the viability, sustainability and safety of the activity. For the implementation of public policies that supply this demand, one of the requirements is the description of local (state) biodiversity. In this sense, this work is the first checklist of bees from the Meliponini tribe for the state of Pernambuco. The work used two methods to generate a list capable of being used by breeders and decision makers in their actions in favor of species activity and conservation. In the first, metadata from the literature and databases published on the internet (CRIA and GBIF) were compiled and available for consultation (UFMG Collection). In the second part of the work, specimens deposited in the ASA / UFRPE collection belonging to the state were identified using the specific bibliography. In the search for metadata, 34 species were listed, distributed in 14 genera, some records represent dubious determinations, which may be overestimating the actual number of species. In the identification of the material in the collection, 32 species were identified, distributed in 14 genera, some determinations could not be confirmed by the lack of reference material for comparison, and some records deal with exotic species that were translocated from their area of natural occurrence. We list 29 native species occurring in the state of Pernambuco and 3 introduced species. A short diagnosis of each species and photographic plates is made. We present the list and discuss biogeographic and conservation implications.
Uso da cera em multiplicações de ninhos de uruçu nordestina (melipona scutellaris, apidae: meliponini)
(2021-02-23) Vieira, Rubem Cláudio Simões; Carvalho, Airton Torres; http://lattes.cnpq.br/5995654016063333; http://lattes.cnpq.br/3306959712309074
Uruçu Nordestina (Melipona scutellaris) is a stingless bee that belongs to the meliponines group, which has geographic distribution throughout the tropics, and can be considered the most diverse group of social bees in the world. The present study aimed to observe whether the supply of wax for multiplication of uruçu nordestina nests reduces the risk of death in newly multiplied colonies, as well as the preference of bees for different mixtures of wax and cerumen. The results found indicate that, although it does not significantly increases the chance of survival of multiplied nests, the supply of these materials allows greater development and weight gain for the colonies, in addition, the species of bee studied in this work prefers to use its own cerumen at the expense of pure Apis wax.
