Título: Melaço de cana-de-açúcar como atrativo alimentar para coleobrocas em bananeiras da cultivar Brs Vitória Autor(es): Fonseca, Weleson Barbosa da Orientador: Menezes, Nivânia Pereira da Costa Abstract: In Brazil, banana (Musa spp.) is a product of strong acceptance and high consumption. The Northeast region stands out as a major banana producer in the country and the state of Paraíba is an important producer, especially for the micro-region of Brejo, which contributes greatly to the production of the State. The cultivar BRS Vitória can be an alternative for banana growers, being essential to study the conditions of cultivation in the municipality of Bananeiras. The objective of this work was to evaluate the incidence of Cosmopolites sordidus and Metamasius spp. using sugarcane molasses as a food attractant. The research was carried out in a 3.5ha orchard of banana trees of cv. BRS Vitória, located at the Federal University of Paraíba CCHSA/UFPB. Four plots with an area of 100 m² were demarcated. Then, the “tile type” traps were made using pseudostem of banana trees that had already produced, receiving 25 ml of the food attractant based on sugarcane molasses diluted at 10% on the cut face. Four traps were distributed in each plot, two containing the food attractant and two untreated controls. After receiving the treatment, the traps were distributed next to the banana clumps, with the cut part facing down, being evaluated every 7 days to remove and carry out the counting and identification of the insects, the traps being replaced by new ones every 14 days. days. It was possible to conclude that the use of sugarcane molasses showed high efficiency in capturing C. sordidus and Metamasius spp; the infestation of C. sordidus is well above the level of economic damage, indicating the need for control; it is necessary to keep monitoring and attention to the levels of Metamasius spp infestation in banana cv. Victory in Brejo region. Editor: Universidade Federal da Paraíba Tipo: TCC

Manejos básicos para fortalecimento e multiplicação artificial de abelhas Melipona scutellaris Latreille, 1811

Título: Manejos básicos para fortalecimento e multiplicação artificial de abelhas Melipona scutellaris Latreille, 1811 Autor(es): Gonçalves, João Pedro da Silva Orientador: Silva, Maurizete da Cruz Abstract: The creation of stingless native bees essentially depends on the availability of natural resources. However, in certain regions and at different times of the year, there is a scarcity of these resources, leading to the weakening of colonies. Therefore, the present study aimed to strengthen colonies of the Uruçú Nordestina bee (Melipona scutellaris) at the meliponary Júlio Goldfarb of the Federal University of Paraíba (UFPB) – Campus III, in the municipality of Bananeiras–PB, through the provision of supplementary feeding. In March 2022, the meliponary had nine colonies of Uruçú Nordestina bees (Melipona scutellaris), housed in two different hive models, four were in INPA-type boxes, and five were in Nordestina-type boxes. In all colonies, a reduced number of adult individuals, a small amount of brood cells, the presence of phorid flies (Pseudohypocera kerteszi), and a reduced number of food pots (nectar and pollen) were observed. Based on this, a feeding and sanitary management protocol was established, aiming at strengthening the colonies and controlling phorid flies. The protocol consisted of offering an energy feed consisting exclusively of water and sugar (syrup) in the following proportions: 1:1; 2:1; 3:1; and 5:1. These changes in proportions allowed a significant reduction in sugar consumption without affecting the reproductive performance of the colony, making it possible to carry out the first colony divisions in September. As indicated, the study began with nine weak swarms and ended after eleven months of protocol application with 29 strong colonies, representing an increase of 107.12% in the roster. It is concluded that the implementation of an adequate feeding protocol, the acquisition of new swarms to diversify genetics, and the application of artificial divisions significantly contributed to the increase in the roster. Therefore, these practices are essential in meliponiculture, ensuring not only an increase in the roster but also the healthy development of colonies and meeting animal welfare standards.

Desenvolvimento da mucosa jejunal de frangos de corte linhagem caipira alimentados com farelo da semente de cupuaçu (Theobroma Grandiflorum)

Título: Desenvolvimento da mucosa jejunal de frangos de corte linhagem caipira alimentados com farelo da semente de cupuaçu (Theobroma Grandiflorum) Autor(es): Cabral, Elyson Figueiredo da Silva Orientador: Moreira Filho, Alexandre Lemos de Barros Abstract: The aim of this study was to evaluate the effect of adding different levels of cupuaçu seed meal to the diet of free-range chickens on the development of the jejunal mucosa and goblet cell count. Three hundred birds of the Label Rouge free-range lineage were used, distributed in a completely randomized experimental design with five treatments, 0, 7, 14, 21 and 28% inclusion of Cupuaçu seed meal in the diet, with five replicates of 12 animals per treatment. At 14 and 28 days of age, the animals were weighed and five animals per treatments were euthanized to collect samples from the jejunal intestinal segment. The variables analyzed were villus height, villus width, crypt depth, villus/crypt ratio, muscle layer thickness, absorption area and goblet cell count. Data were submitted to regression analysis and the means of all treatments were compared with the control group, using the Dunnett test. The use of cupuaçu seed meal altered the development of the intestinal mucosa, influencing (p<0,05) in a linear decreasing the variables such as villus height, crypt villus ratio, villus width and villus area. The variables muscle layer thickness and the number of goblet cells were influenced (p<0.05) in a linear and increasing manner. The inclusion of cupuaçu seed meal in the diet of Label Rouge broilers at high levels (14, 21 and 28%) negatively impacts the development of the intestinal mucosa, which can impair the processes of digestion and absorption of nutrients.

Título: Fauna edáfica e atributos químicos do solo sob diferentes manejos culturais Autor(es): Silva, Zenaide Gomes da Orientador: Araújo, Raunira da Costa Abstract: Soil quality is defined by its ability to develop its functions, within the limits of each ecosystem. The aim of this research was to evaluate the chemical and fertility properties of the soil and the structure of the soil fauna community in different cultural management systems, in the Agriculture sector and in the Goat pasture of the Center for Human, Social and Agricultural Sciences. The work was carried out in 2022 and 2023, in the dry and rainy seasons, and the used areas for the research were: coffee consortium with Gliricidia sepium, citrus and coconut orchard, mandala and goat farming pasture. In all systems, six simple soil samples were collected to form a composite sample at a depth of 0-0.20 m to determine the chemical and fertility characteristics of the soil. To collect soil fauna, six PROVID type fall traps were installed in each area, remaining in the field for 72 hours. The data from the soil samples were subjected to analysis of variance and the means were compared using the Tukey test at 5% probability. To assess the diversity of soil fauna, the Shannon diversity index (H’), Pielou Equability (J’) and Simpson diversity index (C) were used. There was a significant difference between the areas in relation to the chemical attributes of the soil. The coffee and Gliricidia sepium consortium presented higher average values of the (C) and (H’) indices in relation to the other areas, regardless of the analyzed period. However, when comparing the evaluation periods, the dry period showed higher means of (C) and (H') in the areas of the coffeeconsortium, pasture and orchard in relation to the rainy period. The adopted cropping systems by the Agriculture sector and Goat pasture exerted significant influences on all chemical attributes of soil quality. The Collembola order represented 48.27% of the individuals identified in the two years of evaluation. The diversity of soil fauna was bigger in the area of the coffee consortium with Gliricidia sepium, regardless of the evaluation period. The dry period gave a bigger diversity of soil fauna. Collembola was the order with the biggest similarity in the studied areas. Editor: Universidade Federal da Paraíba Tipo: TCC
