This study evaluated the effectiveness of the entomopathogenic fungus Metarhizium anisopliae, applied by spraying, for the biological control of this pest in commercial sugarcane fields. Aspects of fungal biology, infection mechanisms, application methodology, environmental factors influencing efficacy, and impacts on production were analyzed. The results demonstrated near-total suppression of the spittlebug population in the short term, although reinfestation occurred later, highlighting the need for repeated applications and integration with other management practices. The study evidences the potential of M. anisopliae as a sustainable alternative to chemical control, promoting Integrated Pest Management (IPM) strategies in sugarcane cultivation.

Autor(es): Souza, Hamilton Leite Primeiro Orientador: Pereira, Lucas Felisberto Primeiro Membro da Banca: Pereira, Lucas Felisberto Segundo Membro da Banca: Oliveira, Danilo Gomes Terceiro Membro da Banca: Barros, George Oliveira Abstract: Cotton (Gossypium hirsutum) is one of the main crops of global economic relevance and a strategic commodity for Brazilian agribusiness, particularly in the Cerrado biome. However, the high cost of mineral fertilizers and adverse edaphoclimatic conditions limit both productivity and the sustainability of cotton cultivation. In this context, plant growthpromoting microorganisms (PGPM) emerge as a promising alternative to reduce dependence on chemical inputs, enhance nutrient use efficiency, and improve the physiological development of plants. The present study aimed to evaluate the effect of inoculation with Priestia aryabhattai, Pseudomonas fluorescens, and Priestia megaterium on the growth and productivity of cotton. The experiment was carried out under field conditions in São Desidério, Bahia, Brazil, using a strip design with five treatments and three replications. Morphological, nutritional, and productive parameters were analyzed, including plant stand, leaf and seed nutrient content, and lint and seed cotton yield. The results showed that P. aryabhattai promoted greater initial vigor and plant population, while P. megaterium stood out for lint yield (107.20 @/ha), and P. fluorescens achieved the highest seed yield (128.49 @/ha). The consortium of the three microorganisms resulted in the greatest number of bolls per plant and the highest total productivity (335.92 @/ha), indicating a synergistic effect among the species. It is concluded that microbial inoculation, whether used individually or in combination, represents an efficient and sustainable biotechnological tool for increasing cotton productivity, contributing to the reduction of mineral fertilizer use and the regenerative management of agricultural soils Editor: Instituto Federal Goiano Tipo: Trabalho de Conclusão de Curso Fri, 19 Sep 2025 00:00:00 GMT https://repositorio.ifgoiano.edu.br/handle/prefix/6966 2025-09-19T00:00:00Z https://repositorio.ifgoiano.edu.br/handle/prefix/6962 Título: BIOPROSPECÇÃO DE MICRORGANISMOS PARA COMPOSTAGEM DE RESÍDUOS ALIMENTARES Autor(es): Silveira, André Luiz Rodrigues da Primeiro Orientador: Santos, Leonardo de Castro Primeiro Membro da Banca: Cardoso, Aline Assis Segundo Membro da Banca: Kamila, Aline Cristiane Abstract: The sustainable management of organic waste, particularly food waste, represents a growing challenge due to the large volume disposed of in landfills in Brazil. The Brazilian Cerrado, recognized as a global biodiversity hotspot, harbors microorganisms with the potential to contribute efficiently to organic waste decomposition. This study aimed to prospect, isolate, and morphologically characterize native Cerrado microorganisms with the potential to accelerate food waste decomposition. Samples were collected from a Cerrado area at the Federal Institute of Goiás, Hidrolândia Campus, using the cooked-rice baiting method. After bait colonization, the microorganisms were isolated on potato dextrose agar (PDA), purified, and subjected to macroscopic and microscopic characterization for preliminary identification at the genus level. The results indicated four main genera: Trichoderma, Penicillium, Fusarium, and Rhodotorula, with Trichoderma being the most frequently detected genus among the isolates. According to the literature, the identified genera include species associated with organic matter decomposition and the production of enzymes of biotechnological interest. Trichoderma plays an important ecological role in cellulose and hemicellulose degradation and has considerable potential as a composting accelerator and plant growth-promoting agent. Penicillium contributes significantly to waste decomposition and phosphorus solubilization, thereby improving the nutritional quality of the final compost. Saprophytic species of Fusarium are associated with lignocellulose degradation, whereas Rhodotorula acts predominantly during the initial stages of decomposition due to its ability to assimilate simple sugars and produce bioactive metabolites. These findings demonstrate the feasibility of obtaining culturable microorganisms associated with Cerrado soil and litter and provide a basis for further studies involving molecular identification, enzymatic characterization, and composting assays, which are necessary to confirm the biotechnological potential of the isolates.

This study evaluated the effects of mineral fertilization (0, 50 %, and 100 % of the recommended rate) and the biostimulant Vitacomplex on the structure and diversity of soil fungal and bacterial communities in a greenhouse experiment. A completely randomized design was used, with five treatments and eight replicates (40 experimental units), combining mineral fertilization levels with the presence/absence of Vitacomplex. Soil sampling was performed at 90 days after sowing (DAS) for molecular characterization of microbial communities by DNA sequencing targeting the bacterial 16S rDNA and fungal ITS regions, followed by relative abundance analyses, hierarchical clustering/heatmaps, and alfa-diversity metrics (richness, Shannon, and Simpson). The results indicated dominance of Ascomycota and Basidiomycota in the fungal community and an increase in potentially beneficial taxa in the Vitacomplex treatments (e.g., Trichoderma sp., Chaetomium sp., and Clonostachys sp.), whereas the control showed a higher proportion of genera associated with potential phytopathogenicity (e.g., Fusarium sp. and Alternaria sp.). For bacteria, predominant division included Proteobacteria, Actinobacteria, and Firmicutes, with enrichment of functional genera in the Vitacomplex treatments (e.g., Bacillus sp., Streptomyces sp., Paenibacillus sp., and Rhizobium sp.). The highest microbial richness (fungi and bacteria) was observed in the 50 % fertilization + Vitacomplex treatment, suggesting that partial reduction of mineral fertilizer, when associated with the biostimulant, may favor the taxonomic diversity of the soil microbiota, with greater relative abundance of taxa associated with relevant ecological functions.
