Abstract: Fruit cultivation faces constant phytosanitary challenges due to the incidence of pest mites, which has driven the growth of biological control as a sustainable alternative to the intensive use of chemical pesticides. In this context, this study aimed to gather and analyze information on the use of entomopathogenic fungi as control agents for these mites in fruit crops, highlighting the main genera, reported efficiency, and research gaps. The methodology adopted consisted of a Guided Literature Review, with a qualitative-quantitative approach, carried out through searches in the Google Scholar, SciELO, and CAPES Periodicals databases, spanning the period from 2008 to 2025. After applying selection criteria to an initial pool of 1,560 publications, 16 studies relevant to the fruit production chain were analyzed. The results demonstrated the predominance of the genera Beauveria and Metarhizium, which account for over 60% of the research, followed by the genus Cordyceps with 17.6%. The analysis evidenced mortality rates exceeding 90% in the laboratory, contrasting with the variability of efficiency in the field due to the fungi's sensitivity to abiotic factors. It was also observed that the association of fungi with chemical acaricides can promote synergism, while the mixture between different fungal species tends towards antagonism. Thus, the use of entomopathogenic fungi constitutes an effective strategy for controlling pest mites in fruit crops; however, greater advances in formulation technologies and the selection of specific isolates are needed to ensure their technical viability in Integrated Pest Management.

      <title>Dinâmica de regeneração por pousio de encosta degradada no semiárido</title>

      <description>Título: Dinâmica de regeneração por pousio de encosta degradada no semiárido

Abstract: The Caatinga biome covers an area of 850,000 km² in the Brazilian Northeast, where degradation processes already affect 50% of its territory. In this context, the restoration of degraded areas is a fundamental task. Among the various recovery techniques, fallow stands out as a viable alternative. The Aiuaba Ecological Station (ESEC), in Ceará, was created in 1978 and, since then, has remained without degradation-generating use. However, scars caused by unsustainable uses prior to the 1978 intervention are still observed in the ESEC. The objective of this study is, therefore, to evaluate the recovery performance of the preserved Caatinga in fallow. The study evaluated a degraded hillside area in fallow in the Aiuaba ESEC. The assessment of the recovery dynamics was carried out using the Verhulst-Pearl equation parameter. The data are based on remote sensing, using Google Earth Pro, Earth Explorer and UAV images, which are from 1985, 1986, 1989, 1990, 2001, 2004, 2018, and 2023. It was possible to observe the almost total recovery of the area, with an estimated complete recovery 50 years after the first observation. The recovery parameter (λ) calibrated for the preserved Caatinga has a value of 0.220 year⁻¹. This parameter indicates that recovery through fallow in the Caatinga presents a swifter dynamic than the recovery achieved in the degraded areas of Saldaña, Spain. Although the Spanish region is classified as sub-humid, the Brazilian biome demonstrates a superior capacity for response and regeneration.

      <title>Disponibilidade de micronutrientes em solos submetidos a diferentes manejos no semiárido</title>

      <description>Título: Disponibilidade de micronutrientes em solos submetidos a diferentes manejos no semiárido
Autor(es): Fernandes, Mário Neto de França
Abstract: Soil micronutrient availability is a key factor for plant productivity, particularly in semi-arid regions where soils often exhibit chemical limitations due to degradation and intensive land use. Land use for reforestation may favor the availability of micronutrients, bringing it closer to that observed in native forest areas, depending on management practices and time. This study evaluated the contents of copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), and boron (B) in soils under different land uses (eucalyptus plantation, native forest, and degraded area), within two soil classes: Argissolo Vermelho-Amarelo and Neossolo Quartzarênico, in Acaraú, Ceará, Brazil. A 3 × 5 factorial design was adopted (three land uses × five depths: 0–5, 5–10, 10–30, 30–50, and 50–70 cm), with four replicates. Evaluations were carried out in 2022 and 2023. Micronutrient analyses were performed by atomic absorption spectrometry after Mehlich-1 extraction, except for boron, which was extracted with KCl. Data were subjected to tests for normality and homogeneity, followed by mathematical transformations and ANOVA. Results showed that eucalyptus cultivation promoted greater availability of Cu, Mn, and B compared to the degraded area, while Zn contents were higher in the native forest. Micronutrient availability was greater in surface layers, especially for Zn and Mn, with a decreasing trend between the evaluated years. It is concluded that eucalyptus land use contributes to the partial recovery of soil fertility in degraded environments, approaching the condition of native vegetation for some micronutrients.

      <title>Nidificação da abelha Epanthidium tigrinum em ninhos manejados em remanescente de mata de tabuleiro</title>

      <description>Título: Nidificação da abelha Epanthidium tigrinum em ninhos manejados em remanescente de mata de tabuleiro
Autor(es): Sousa, Maria Marcelle Batista Amaro de
Abstract: This study aimed to analyze the nesting behavior of the bee Epanthidium&#xD;
tigrinum (Schrottky, 1905) (Hymenoptera: Megachilidae) in managed trap&#xD;
nests within a remnant of tabuleiro forest, in order to assess its potential&#xD;
for rational rearing. Artificial nests were installed in an experimental area&#xD;
of the Bee Sector at the Federal University of Ceará (UFC), in Fortaleza,&#xD;
Ceará, and were monitored regularly from January 2023 to January 2025.&#xD;
Data collected included the number and seasonality of nests, rates of cell&#xD;
closure and emergence, sex ratio, nest structure, and construction&#xD;
materials. Descriptive statistical analyses were performed. Results&#xD;
indicated that the species is multivoltine, with a nesting peak in August–September, and each female built between 1 and 4 nests.&#xD;
Emergence was recorded in 56.9% of brood cells, with a male-biased sex&#xD;
ratio (41.46% males). Average nest length was 5.94 ± 2.84 cm, and there&#xD;
was a positive correlation between average cell length and number of&#xD;
cells per nest. The main nesting material was dark-colored resin, often&#xD;
mixed with other substances. It is concluded that E. tigrinum shows&#xD;
promise for conservation-oriented management and pollination,&#xD;
provided that adequate resources (pollen, nectar, and resin) and floral&#xD;
planning are ensured.
