    Entomologia Experimentalis Et Applicata, 2026
    Hyperspectral Remote Sensing allows accurate analysis of the developmental stages of insects and their interactions with biocontrol agents. This study spectrally characterizes the life stages of Diatraea saccharalis and evaluates the physiological responses of larvae parasitized by Cotesia flavipes . For this, hyperspectral reflectance data were obtained with high‐precision sensors. The experiments took place in the laboratory under controlled conditions to ensure reproducibility. The measurements covered eggs, larvae, pupae and adults, with emphasis on parasitized larvae. Principal Component Analysis (PCA) was applied to identify relevant significant hyperspectral variations and distinguish biological groups. The results showed significant differences in hyperspectral reflectance between developmental stages and the physiological state of the parasitized larvae. Newly laid eggs and newly formed pupae showed higher reflectance than pre‐hatch eggs and old pupae. The larvae of the first stage were significantly distinguished from the other larval stages by their high reflectance. In adults, the dorsal surfaces of males and females were similar, but the ventral surface of females exhibited a distinct pattern. Larvae parasitized by C. flavipes showed differentiated hyperspectral signatures, especially in the near‐infrared (NIR) bands, reflecting biochemical and physiological changes caused by parasitism. Between 8 and 10 days after parasitism, the reflectance of the larvae became like that of dead larvae and different from those of live or newly parasitized larvae. PCA confirmed the efficacy of hyperspectral reflectance in discriminating against the stages of D. saccharalis . The data generated in this study can integrate a hyperspectral bank for future applications in entomology and biological control, with this technology being able to integrate precision agriculture systems, optimizing for characterization, pest management and reinforcing the sustainable use of agricultural resources.
  • Spectral Signatures of the Developmental Stages of Sphenophorus levis (Vaurie, 1978) (Coleoptera: Curculionidae) on a Natural Diet

    Insects, 2026
    This study investigated the spectral profiles of different developmental stages of Sphenophorus levis, possibly the most important sugarcane pest in the Southeast, Midwest, and South regions of Brazil, given its economic relevance, distribution, and management challenges in sugarcane plantations. Hyperspectral remote sensing (HRS) techniques were employed. Spectral signatures were obtained for eggs, larvae, pupae, and adults using a Pika-L sensor (range, 400–1000 nm). This made it possible to identify distinct spectral patterns for each developmental stage, allowing for the differentiation between eggs, larvae, pupae, and adults. The results indicate the presence of such distinct spectral patterns, which may suggest the potential of hyperspectral imaging for the non-destructive identification of each stage of S. levis, although further investigations are needed to validate this approach. The eggs showed high variability in reflectance, possibly related to compositional changes during embryonic development. The larval instars exhibited a decrease in reflectance with age, likely due to cuticular changes. The evaluated pupae presented spectral differences that coincidentally enabled early sex determination, while adult males and females can also be distinguished based on their reflectance profiles, with females typically showing higher overall reflectance. This spectral library provides a foundation for the determination and sexing of instars, as well as the assessment of quality patterns in this important sugarcane pest. This study highlights the integration of advanced hyperspectral imaging technologies with insect biology to enhance integrated pest management strategies and sheds light on the biological and ecological aspects of the species.
  • Anthropoentomophagy in some states of Brazil: an up-to-date review

    Journal of Insects as Food and Feed, 2026
    While there are well-documented records of anthropoentomophagy practices among numerous Indigenous Peoples and Local Communities in Brazil, it is likely that its prevalence remains significantly underestimated. This review examines a total of 116 edible insect species in Brazil, identified at the species level, categorized into eight orders: Blattodea, Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera, Orthoptera, and Psocodea. Hymenoptera was the most represented order, comprising 79 species (68%). Depending on the species, these insects are consumed in both their immature and adult stages, either raw or cooked, ingested whole, in parts, or as by-products. Given Brazil’s vast sociobiodiversity, edible insects exhibit substantial potential due to their nutritional richness and abundance, playing a crucial role in Traditional Food Systems while also offering promising prospects as sustainable ingredients for both household cuisine and the food industry.
  • Spectral response of guava leaves under infestation by Costalimaita ferruginea (coleoptera: Chrysomelidae)
    Souradji I. Bachirou, Pedro G. Peixoto, David L. Rosalen
    Agricultural and Forest Entomology, 2026
    Guava ( Psidium guajava ) is one of the most important fruit crops in Brazil, being popular due to its availability in all seasons and rich nutritional and medicinal value. However, Costalimaita ferruginea is one of the main pests in guava production and directly interferes with its productivity. Symptoms of attack are often determined by visual observation, which may lead to inadequate characterization of the damage caused by this pest. Areas of guava plants (blocks) and plants with four groups of five leaves per plant (replicates) were considered. This study spectrally characterized the spectral response of guava leaves under infestation by Costalimaita ferruginea (Coleoptera: Chrysomelidae). The spectral signature of the leaves was determined using a spectroradiometer. The spectral signatures showed the guava leaves uninfested, moderately infested (level 1) and severely infested (level 2) by C. ferruginea . The uninfested guava leaves showed lower reflectance in the 500–600‐nm spectral range and higher reflectance in the 750–1000‐nm range. The level 1 infested leaves exhibited moderate reflectance between 500 and 600 nm and lower reflectance between 750 and 1000 nm. In contrast, the level 2 infested leaves had a higher reflectance between 500 and 600 nm and a lower reflectance between 750 and 1000 nm. The uninfested leaves showed lower reflectance in the visible spectrum and higher reflectance in the near‐infrared (NIR) spectrum than level 1 and level 2 infested leaves. It is also noted that as the infestation becomes more severe, the reflectance in the visible increases and the NIR decreases, denoting the typical behaviour of plants under biotic stress. Principal Component Analysis (PCA) and linear regression confirmed the efficacy of hyperspectral reflectance in discriminating the damage levels of C. ferruginea . The data generated in this study can be integrated into a hyperspectral bank for future applications in entomology, damage and pest monitoring.
  • The Response of Dung Beetle Communities to Land Use Change in the Brazilian Cerrado

    Land, 2025
    The transformation of the Cerrado biome into areas with different levels of activity and anthropic pressure negatively impacts biodiversity. This study evaluated the response of the dung beetle community to changes in land use systems: forests, rubber trees, pastures, and soybeans. Five areas were sampled in each system with a minimum distance of 2 km between them. Dung beetles were collected using pitfall traps, and both local (vegetation density, basal area of wooded vegetation, fractal dimension, litter height, electrical conductance (mV), water content in the soil (%), and soil resistance (kPa)) and landscape-related environmental variables (land use and overall composition and configuration of the landscape surrounding the sampling areas) were measured. In total, 2294 specimens were collected and distributed among 34 species and 18 genera. There was no significant difference in abundance between the systems, but differences in the number of species and biomass were observed between forest and soybean systems, as well as a separation of communities between the tree-covered (forest and rubber tree) and open (pasture and soybean) systems. Density and arboreal basal area were the main predictive variables for the diversity of the dung beetle community, reinforcing the importance of vegetation cover for maintaining diversity, whereas local and landscape-related variables influenced community composition.
  • No-tillage effects in bean cultivation and the application of fomesafen on soil dynamics

    Australian Journal of Crop Science, 2025
    Soil quality is defined as the measure of its capacity to perform vital ecological functions for agricultural development. With the expansion of cultivated areas and even their exposure to long periods without plant presence, issues such as erosion and soil nutrient depletion can arise. Therefore, practices like crop rotation or the incorporation of green manures have gained traction in soil preparation for large-scale cultivation. The common bean plant, being a member of the legume family, possesses such capabilities, being a potential nitrogen fixer and contributing to soil maintenance. Thus, this study aimed to assess the effects of cultivating common beans in fallow areas with sugarcane straw and fomesafen application. The experiment was conducted in an area with Eutrophic-Dystrophic Red Latosol. The experimental design was a randomized block design in a 4x2 factorial system, with four replicates, considering leaves straw presence (0, 1, 5, and 10 t ha-1) and two types of herbicide application (with and without application), totaling 8 experimental treatments and 32 plots. Soil chemistry, soil enzymatic activity, leaf area, plant dry matter, and productivity were evaluated. Higher straw quantities in the system improved soil enzymatic activity dynamics and soil chemistry. Plant development was correlated with higher soil enzymatic activity. Thus, it is concluded that in fallow areas: 1) the straw enhances soil quality and common bean productivity; 2) The herbicide (fomesafen) application has no impact on soil dynamics; 3) chemical, physical, and biological soil variables show worse conditions in treatments without straw, regardless of herbicide application; 4) enzymatic activity (β-glucosidase) is higher in the interaction between straw and plants, responding better to soil dynamics compared to physical and chemical variables, resulting in higher common bean productivity. It is recommended to maintain or increase straw coverage to improve soil quality and common bean productivity, with the safe use of the herbicide fomesafen, as it does not negatively affect soil dynamics.

  • Alcoholic fermentation: Proposal to teach biochemical pathways through fractional distillation
    Mariana Rezende Pires, Pedro Gomes Peixoto, Renato Ventresqui Oliveira
    Ecletica Quimica, 2015
    Teaching of biology and chemistry in the schools has been widely discussed. The use of demonstration classes to content assimilation explained in lectures has been rarely used; hampering a better understanding of the students explained the content in the classroom. This article presents a proposal in science education combining theory and practice to facilitate the capture knowledge by students. The use of a simple distillation system for the explanation of metabolic pathways is a methodology that may present improvements in learning.
