“…Estudos revelam que as sementes da maioria das espécies vegetais são danificadas por vários grupos de insetos, destacando-se algumas espécies pertencentes a várias famílias da ordem Coleoptera (Chrysomelidae, Curculionidae, Cerambycidae) e Lepidoptera (Pyralidae) (SOUZA et al, 2011;FERREIRA et al, 2017).…”

O desenvolvimento de insetos em frutos ameaça o potencial de germinação das sementes, sendo responsáveis por perdas em um número variado de espécies nativas e de valor econômico no Brasil. O jatobá é uma árvore grande, com 30 a 40 metros de altura, e possui tronco reto, com cerca de 2 metros de diâmetro, sendo bastante utilizado por populações tradicionais em função de suas diversas utilidades, a partir do uso da casca, das sementes, dos frutos, da seiva e das folhas, tendo seu mercado incentivado pelos vários produtos originados. Pesquisas realizadas em diferentes biomas brasileiros com espécies de árvores leguminosas destacam a predação de sementes e frutos por coleópteros broqueadores, afetando a qualidade da semente destinada à perpetuação da espécie. Portanto, este trabalho tem como objetivo avaliar os danos causados por Rhinochenus stigma em frutos e sementes de Hymenaea courbaril. Constatou-se que esse inseto foi responsável pelo consumo médio de 46,79% do peso de uma semente e que a porcentagem de germinação das sementes danificadas foi de apenas 3%. A predação de sementes por R. stigma possui um efeito direto sobre a qualidade fisiológica das sementes de H. courbaril e evitar esses danos são, significativamente, importantes para os coletores de frutos e sementes que o utilizam para confecção de artesanato, bem como para o uso em planos de reflorestamento. Palavras-chave: Insecta. Cryptorhynchinae. Jatobá. Abstract The development of insects in fruits threatens the seeds germination potential and is responsible for losses in a varied number of native species and of economic value in Brazil. Jatoba is a large tree, 30 to 40 meters high, and has a straight trunk, about 2 meters in diameter, it is widely used by traditional populations due to its diverse uses from the use of bark, seeds, fruits, sap and leaves, with its market encouraged by the various originated products. Research carried out in different Brazilian biomes with legume tree species highlights the seeds and fruits predation by boring coleoptera, affecting the quality of the seed aimed at the species perpetuation. Therefore, this work aims to evaluate the damage caused by Rhinochenus stigma in fruits and seeds of Hymenaea courbaril. It was found that this insect was responsible for the average consumption of 46.79% of the weight of a seed and that the germination percentage of the damaged seeds was only 3%. The seeds predation by R. stigma has a direct effect on the physiological quality of H. courbaril seeds and avoiding these damages is significantly important for fruit and seed collectors who use it for making crafts, as well as for use in reforestation plans. Keywords: Insecta. Cryptorhynchinae. Jatoba.

“…Originally, from northern and northeastern regions, this species is present throughout the entire Brazilian territory, commonly found in pastures, crops, orchards, roadsides, tracks, and wastelands. It generally occurs in sandy and dry soils (Ferreira, Valente, & Santos, 2017). In soil excavations, this species roots achieve 0.63 m depth.…”

Several plant species have been studied as reinforcement elements against landslides at slopes, either to protect against the splash effect offered by shoots or anchoring the soil by the root system. The objective of this work was to investigate the influence of roots from shrub species over the soil mechanical attributes such as cohesion and angle of internal friction at the São Francisco riverbank, northeastern Brazil. A trench was excavated under the treetop of every shrubby individual, sampling blocks at 0-0.25, 0.25-0.50, 0.50-0.75, and 0.75-1.00 m depths. The moisture contents, particle size, liquidity limits, plasticity and actual specific mass of the samples were determined. The soil physical and mechanical attributes such as initial and final specific weight, initial and final void content, initial and final degree of saturation, shear resistance peaks, cohesion, and internal friction angle were identified through direct, elementary, consolidated, and undrained tests. In the samples with Solanum paniculatum, Mimosa pigra species, the highest values for cohesion were registered for the samples with roots. Sesbania virgata presented the greatest variation in cohesion and internal friction angle among samples with and without roots. The position and root status influenced the results of the direct shear tests.
