This study aims to survey the breeders of the Northeastern uruçu bee (Melipona scutellaris) in the municipality of Bonito, demographically characterizing the area and the breeding system. Semi-structured and free interviews were carried out and 9 (nine) meliponaries were identified. The presence of beekeepers was verified in the regions demographically classified as Agreste, Brejo de Altitude and Zona da Mata, being the properties of the Rural type. Regarding the number of hives, 101 colonies of uruçu bee were observed, with an average of 11.2±12.1 for the 9 evaluated meliponaries, where only 01 creator contained the amount of 42 colonies and the others varied from 02 to 15. If the traditional uruçu bee breeders in Bonito-Pernambuco, most of them have a breeding system with a low technological level, making it necessary to take actions that lead them to perceive themselves as true guardians of this biodiversity, in order to conserve this genetic resource in a sustainable way. continued with self-sustainable management.

The increasing use of pesticides in production systems as a way to eliminate pests or weeds has impacted the survival of pollinating insects of these crops. Among these, bees have been the most harmed, and there have been reports of alarming declines in the number of colonies around the world. With the increasing use of glyphosate-based herbicides, there is a need to assess the impacts of this pesticide on bees, as bees are responsible for pollinating 73% of the world’s cultivated vegetables and their disappearance can cause serious damage. the economy. The objective of this research was to evaluate the behavioral and biochemical alterations resulting from the ingestion exposure of Africanized bees to glyphosate active ingredient. The research was conducted at the Animal Genetics and Bee Breeding Laboratory of the Department of Zootechnics of the Federal Rural University of Pernambuco (DZ / UFRPE), and was divided into two stages: 1 - Preliminary bioassay with exposure time of 6 hours; and 2 - Bioassay with 24 hours of exposure. The experiments were performed in triplicate, totaling the use of 90 worker bees in both stages. During the experiments, the bees were kept in a climate-controlled environment with an average temperature of 23.9 ± 0.8 ° C and 50% humidity, distributed in three treatments, forming the following groups: T1 (control) - 1: 1 60 sucrose and 60 mL distilled water, T2: 960 μL glyphosate added to 120 mL syrup (1: 1 60 g sucrose and 60 mL distilled water), and T3: 1,920 μL glyphosate added to 120 mL syrup (1: 1 60 g sucrose and 60 ml distilled water). The commercial product used was Roundup®, using the minimum dose indicated by the manufacturer. Bees’ behavior was observed every 30 minutes. The biochemical analyzes performed were related to lipid, total sugar, glycogen and protein content. Behavioral alterations are observed after 2h of exposure, showing as desorientation and lethargy behavior as controls T2 and T3 bees, differing statistically from T1 control. The first bee deaths occur at T2 and T3 within the first 6 hours of the experiment. In the biochemical analysis used, glycogen and sugars values are reduced, totaling the effects of glyphosate inclusion (T2 and T3), differing from the use of treatment control. The protein and lipid values did not present statistically significant difference between the three treated. It was concluded that an ingestion of glyphosate caused behavioral changes and biochemical parameters of Africanized bees.

Bees in Brazilian beekeeping are predominantly hybrid, with little knowledge about the health of these bees, especially in the Northeast region of Brazil. As diseases and pests compromise the development of the colony, causing damages in the production, the objective of this work was to characterize colonies of Apis mellifera bees resistant or not to Nosema and Varroa destructor in the Agreste and Zona da Mata regions of Pernambuco. Samples were collected from sixty - three colonies for Nosema analysis and fifty - eight for analysis of Varroa destructor. The collected samples were preserved in 70% alcohol, to prevent the bees from perishing and to carry out the analyzes. In the results it was observed that 54% of the colonies did not present Nosema spores, 35% presented in the very light scale and 11% light. In the Varroa destructor analysis a mean of 3.44 ± 4.69 was observed. The analyzed colonies of Apis mellifera (Africanized) bees from the Zona da Mata and Agreste of Pernambuco are characterized as resistant to Nosema and Varroa destructor, presenting colonies with low infection rate and infestation.
