There is little information about the Pompilidae fauna in Brazil’s Deciduous Forests and no reports about how this taxon manifests itself in the Mata Seca State Park (PEMS), which is considered one of the most important for the protection of this forest in Brazil. This work was carried out to record the occurrence of Pompilidae in the Deciduous Forest of the PEMS. The records were occasionally taken in the PEMS during 24 days in 2021. A total of 16 individuals of two genera, four species, and three morphospecies of Pompilidae were collected. The Pepsis albocincta Smith, 1855; Pepsis apicata Taschenberg, 1869; Pepsis decorata Perty, 1833; and Entypus taschenbergii (Dalla Torre, 1897) species are new to Brazil’s dry forest, which reaffirms the importance of the PEMS in ensuring the protection of biological diversity in the Deciduous Forests of Brazil.

Maize is very important in Brazilian agribusiness: it is the second most produced grain in the country. Crops need to be fertilized, especially with nitrogen, to achieve high yields. This study aimed to evaluate the contribution of Azospirillum brasilense in maximizing the use of nitrogen by maize crops after soybean cultivation in the same soil. This study was carried out at the Experimental Farm of the State University of Minas Gerais (UEMG), Passos unit. The experiment consisted of planting maize in the same soil where soybeans had previously been grown, with a strip- and split-plot design. The seeds in one strip were inoculated with Azospirillum brasilense, and those in the other strip were not. Each strip was divided into 24 plots measuring 18 m², which received nitrogen doses as urea (0, 10, 35, 70, 140 and 210 kg ha−1 of N), in four replications. Seed inoculation did not result in statistical differences. The plots that received the treatment with chemical nitrogen fertilization exhibited the same results as those that did not, which can be explained by the previous soybean cultivation letting nitrogen in the soil and/or by the effect of Azospirillum brasilense.

The peach palm heart is a hypocaloric gourmet vegetable, rich in fiber and minerals such as potassium, calcium, and magnesium, and it can be incorporated into calorie restriction diets. Minimum processing consists of sanitizing and cutting the products before reaching the consumer, providing convenience to consumption without losing its quality, thus resulting in sufficient shelf life for distribution and marketing. Sanitation, appropriate packaging, and refrigeration are essential practices to extend the shelf life of minimally processed products. Therefore, this study evaluated the quality of peach palm heart produced in Pariquera-Açu – SP, minimally processed in the form of chopped cut and stick, packed in different plastic packages and kept under refrigeration (10 ± 0.5 °C and 85 ± 5% RH) for 9 days. Hearts-of-palm, in chopped cut and stick, packed in PET and PP trays with lids, had their fresh masses and luminosity preserved for 9 days, but there was a failure in the sealing of the lid, which allowed gas exchange with the environment, compromising its quality. The peach palm heart cut in stick, packed in a stretchable PVC coated PE tray, provided protection and efficiency in maintaining quality. The packaging of chopped hearts-of-palm in LDPE packages (0.04 and 0.07 mm), over the storage time, resulted in a high CO2 concentration inside the package, thus, these packages are not recommended.
桃心是一种低热量的美食蔬菜，富含纤维和钾、钙、镁等矿物质，可用于限制热量的饮食中。最低限度的加工包括在产品到达消费者之前对其进行消毒和切割，在保证质量的前提下为消费提供方便，从而为分销和营销提供足够的保质期。卫生、适当包装和冷藏是延长微加工产品保质期的基本做法。因此，本研究对产于南太平洋帕里奎拉-阿苏（Pariquera-Açu - SP）的桃心质量进行了评估。桃心以切碎和切条的形式进行微加工，用不同的塑料包装，并在冷藏条件下（10 ± 0.5 °C 和 85 ± 5% 相对湿度）保存 9 天。以切碎和切条形式包装在带盖 PET 和 PP 托盘中的棕榈心，其新鲜度和光亮度可保存 9 天，但盖子的密封性出现故障，导致与环境进行气体交换，影响其质量。切成棒状的桃心包装在可拉伸的 PVC 涂层 PE 托盘中，既能提供保护，又能有效保持质量。用低密度聚乙烯包装（0.04 毫米和 0.07 毫米）包装切好的桃心，在贮藏期间，包装内的二氧化碳浓度很高，因此不建议使用这种包装。

The Atlantic Forest is among the 36 biodiversity hotspots of the world. The southern region of this biome covers 52 conservation units (CUs), including the Bela Vista Biological Refuge (RBBV), which has actions based on biodiversity conservation, scientific research, and environmental education. Biodiversity is the basis for different ecosystem services that can be carried out by social wasps, essential in terrestrial environments. Brazil has the richest fauna of social wasps (Vespidae, Polistinae) on the planet (381 species); however, some Brazilian states, such as Paraná, are “undersampled.” This study was carried out with the goal of inventorying the fauna richness of social wasps in the Atlantic Forest. This biome is located in the RBBV, Paraná, Southern Brazil, and the collections took place from September 2021 to May 2022, totaling 20 days of sampling. Active search with the aid of insect entomological nets in trails near aquatic environments was used. A total of 18 species of social wasps were recorded, including four new records for the state of Paraná. This study recorded species restricted to some biomes and others of wide geographical occurrence; therefore, the RBBV is an important CU for maintaining the fauna of social wasps in the state of Paraná.

Strawberry-producing technologies are rapidly developing for the cultivation of small red fruits. The Southern Minas Geraisstands out in Brazil’s production. In this context, the search for production improvements via nutrition and quality maintenanceis indispensable for cultivation. This study aimed to evaluate how different silicon doses can influence the production andquality of strawberry fruits from national and imported seedlings. For the experiment, strawberry seedlings from the ‘SanAndreas’ cultivar, of national and Chilean origins, were used. The plants were grown in a semi-hydroponic system andcorresponding silicon doses (0, 500, 1000, 1500 and 3000 mg L−1) were tested via foliar application. A split-plot design wasused, in a 5×2 factorial scheme, with four replications and 10 plants per plot. By physical and physicochemical evaluations,alterations in the production and quality of the fruits were analyzed. The foliar application of silicon – to complement thestrawberry nutrition – did not increase the productivity or quality of the fruits, regardless of the nationality of the seedlings.The only difference regarding origin was associated the vigor of plants.

The cultivation of dragon fruit has been standing out considerably in Brazil, however, although on the rise, information onthe cultivation of this fruit, such as pruning management in young orchards and the use of superabsorbent polymer in thecrop, is scarce. In this sense, in order to remedy producers’ obstacles regarding the management of orchard formation, theobjective of this study was to evaluate the influence of pruning management and the efficiency of hydrogel in the vegetativeand reproductive development in two different species of dragon fruit (Selenicereus undatus and Hylocereus polyrhizus),in addition to defining the best dose of the polymer to be used in the crop. The work was developed at IFSULDEMINAS –Machado Campus. The design used was the randomized block design, in a factorial scheme (2x2x3), the first factor beingcomposed of the two species of dragon fruit, the second, by two cladode pruning levels (with and without pruning), and thethird, by three doses of the superabsorbent polymer Hydroplan-EB® (0; 1.5; 4.5 g plant-1). The following characteristicswere evaluated: number and length of shoots; total number of flowers; total number of fruits; number of aborted flowers;picking percentage; mean fruit mass; longitudinal and transverse diameter of fruits; peel thickness; pulp yield; peel massand productivity. The practice of cladode pruning, as well as the application of the superabsorbent polymer, did not influencemost of the characteristics evaluated. Further studies should be conducted to delve deeper into the management techniquesused in this study.

The decomposition of legumes in the soil over time can be described by nonlinear sigmoid models. Thus, this study aimedto describe and to compare the fit of the nonlinear sigmoid models, Logistic and Gompertz, to the CO2 mineralization of fourlegume species over time in the soil, and indicate the most suitable model. Furthermore, it is also proposed to evaluate the CO2mineralization of legumes from two different edaphoclimatic conditions when added to the soil under controlled temperatureand humidity conditions. The following legume species used in green manure were evaluated: Arachis pintoi (forage peanut),Calopogonium mucunoides (calopo), Stylosanthes guianensis (Caribbean stylo), and Stizolobium aterrimum (mucuna). Arandomized block design with four replications was used. The soils from both areas are classified as Red-Yellow Latosol andhave a clayey texture. The mineralized carbon was measured at 48, 96, 144, 192, 240, 312, 384, and 480 hours fromthe beginning of incubation. Legumes in different locations had the same amount of potentially mineralizable carbon, andmicroorganisms had the same adaptation time to reach the maximum decomposition rate. The maximum decompositionrate occurs at the beginning of mineralization, and therefore the Gompertz model was more suitable than the Logistic modelin describing the decomposition of the four legumes in the soil.

The species Myrmecophaga tridactyla, Myrmecophagidae, is widely distributed in the Neotropics regions and is popularlyknown as the giant anteater. It is considered a generalist species regarding habitat and can be found in human-modifiedareas such as pastures and crops. However, there is limited information about the species in agricultural ecosystems. Dueto its threatened status and the absence of records in the Campos das Vertentes region, which has only 1.04% of its areaincluded in Conservation Units, this study aimed to report the unprecedented occurrence of M. tridactyla in the municipalityof Ritápolis, Campos das Vertentes, Minas Gerais, in a transitional region between the Atlantic Forest and the Cerrado. Twooccasional records were made on a rural road in this municipality. Therefore, this record increases our knowledge about thespatial distribution of M. tridactyla in the state of Minas Gerais, provides information about the species in human-modifiedlandscapes, and supports the need for more Conservation Units in the Campos das Vertentes region.
食蚁兽(Myrmecophaga tridactyla)广泛分布于新热带地区，俗称巨食蚁兽。它被认为是一种多栖物种，可以在牧场和农作物等人类改造过的地区找到。然而，关于该物种在农业生态系统中的信息有限。由于其受威胁的地位和在Campos das Vertentes地区的记录的缺乏，只有1.04%的面积被列入保护单位，本研究旨在报告在米纳斯吉拉斯州的Ritápolis市，大西洋森林和塞拉多之间的过渡地区，史无前例地发生了三趾松。在本市的一条乡村公路上做了两次偶然的记录。因此，这一记录增加了我们对米纳斯吉拉斯州三爪草空间分布的了解，提供了人类改造景观中该物种的信息，并支持在坎波斯达韦滕斯地区建立更多保护单位的需求。

Genetic improvement is the main responsible for the increase in tilapia production in the last decades. However, the toolsused in broodstock selection have increased the mating of related animals, and as a consequence, animals with morphometricanomalies have appeared. In view of the above, this work was carried out with the objective of evaluating the effect of bodydeformities on the meat yield of tilapia. A total of 106 animals from assisted reproduction of the UFLA tilapia breedingprogram were used, among which 53 had visible deformities. The animals were weighed, measured, and photographed witha digital camera and had their body areas measured using computer software. Afterward, the animals were slaughtered andthe fillet from the left side was removed to measure weights and yields. On the right side, cuts were made to measure themeat volume in the carcass. The residues were weighed separately to analyze processing losses. Using the software R-studiothe normality test was applied to all data and afterwards, the tests of means and correlations between morphometries andyields were performed. No morphometric differences were identified between the groups, but deformed animals showedsmaller caudal areas and caudal peduncles and high correlations with fillet weight. However, normal fish showed higherfillet yield and lower residue production. It is concluded that the anomalies imply lower filet yield and a higher amount ofprocessing residues.

The world fish production has been growing in response to the great demand for healthy food and Brazil has the conditions to export fish. However, the development of the chain is necessary, with the use of production techniques and tested genetic material. Tilapia is an excellent breeder, however studies on specialized varieties need to be conducted. In view of the above, the present study aimed to evaluate the applicability of the MGTUFLAP variety as a matrix in diallel crossings with two commercial varieties widely spread in the territory and the performance of the offspring. Data from offspring originating from nine distinct genetic groups produced in the 2015/2016 aquaculture year were collected in the fish farming sector of the Federal University of Lavras. All animals were weighed and had their morphometry measured, then slaughtered and processed in order to obtain the weight of the cuts and processing residues. The general and specific combining ability and the maternal effect were estimated and the morphometric averages, cuts and yields were grouped using the Skott Knott method (p<0.05). In general, the genetic groups descending from MGTUFLAP variety showed worse performance for head size and filet weight, but obtained higher filet yield and lower carcass yield. The adapted variety showed good general and specific combining ability, as well as better maternal effect on the traits of head weight and filet yield. We conclude that the variety MGTUFLAP presents good results in crossbreeding and the females are an excellent option for maternal line.
