The timely detection, prevention, and mitigation of pest damage are paramount to ensuring the quality and safety of agricultural products. However, traditional manual methods for pest identification are not only cumbersome and resource-intensive but also prone to subjectivity, leading to sub-optimal identification efficiency and precision. To address the aforementioned issues, this study introduces an intelligent pest recognition system grounded in a convolutional neural network (CNN). This system integrates a multi-scale hybrid attention module with a residual network, specifically tailored for pest classification. Initially, a comprehensive experimental dataset was compiled by acquiring pest samples through three distinct methods. Subsequently, this dataset was utilized to train the improved CNN. By incorporating a multi-scale hybrid attention module and reconstructing the classifier module within the original ResNet18 model, a specialized CNN named PestNet was developed. Experimental results demonstrate that PestNet attains an average recognition accuracy of 93.61%, marking a significant improvement of 2.04% compared to the baseline ResNet18 network. This study comprehensively validates the effectiveness of the PestNet network model in pest recognition tasks through a series of rigorous evaluation metrics. Further ablation experiments confirm the necessity of each modification in the model and their positive impacts on overall performance. This research not only demonstrates the immense potential and broad application prospects of deep learning in pest recognition but also presents a potential intelligent and convenient technological solution for agricultural pest management.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"55 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147777129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We quantified protein concentrations in larval pollen provisions and measured morphometric traits (intertegular span, head width, and head length) in individuals reared from trap nests collected during the wet and dry seasons. Using nonparametric statistics and multivariate analysis, Multiple Factor Analysis (MFA) and Hierarchical Clustering on Principal Components (HCPC), we tested associations among protein content, morphology, sex, species, season, and sampling site. Centris tarsata individuals were consistently larger and associated with higher-protein pollen, while C. analis showed greater variation in size, particularly during the rainy season.

This study aimed to evaluate the sublethal concentration toxicity of Bacillus thuringiensis, var.

Subsequently, the results demonstrated that LC<sub>25</sub> resulted in a 22% reduction in larval survival percentages, so larval midgut tissues treated with the sublethal concentration (LC<sub>25</sub>) were isolated for further cytogenetic analysis. Consequently, Btk treatment markedly disrupted midgut cells, inducing micronuclei (MN) formation and reducing SfDnmt2 mRNA gene expression considerably. Furthermore, cytotoxicity has been shown in S. frugiperda midgut epithelial cells by cellular disorganization, fragmentation and protrusion, peritrophic matrix rupture, and microvilli degeneration. Btk sublethal concentration also induced cytotoxicity by causing apoptosis and necrosis in S. frugiperda midgut cells.

This study assessed the selectivity and toxicity of six registered insecticides, spiromesifen, deltamethrin, lambda-cyhalothrin, abamectin, chlorfenapyr, and imidacloprid, to identify options compatible with the conservation of C. septempunctata in bean fields. The insecticides were applied to eggs, third-instar larvae, pupae, and adults, with distilled water serving as the control treatment. Insecticide exposure significantly affected survival, development, and reproductive performance depending on the compound and developmental stage. Spiromesifen was the least toxic, causing minimal effects on egg viability and no significant reductions in adult fecundity when exposure occurred during larval or adult stages. Chlorfenapyr also showed comparatively moderate effects, although some reductions in egg viability and adult reproduction were observed. In contrast, deltamethrin caused extreme toxicity, resulting in complete egg mortality and preventing survival of larval and adult stages. Abamectin, lambda-cyhalothrin, and imidacloprid resulted in major lethal and sublethal effects, including delayed development, fewer adults emerging, and significant reductions in fecundity and egg viability. Exposure during immature stages led to severe carry-over effects that impaired the reproductive capacity of surviving adults. We conclude that spiromesifen and, to a lesser extent, chlorfenapyr appear comparatively safer for C. septempunctata and may be considered for integration into integrated pest management programs aimed at conserving natural enemies.

The cicada Quesada gigas (Hemiptera: Cicadidae), commonly known as the coffee cicada, is a significant pest in coffee cultivation across the Americas. Using the MaxEnt algorithm, we predicted the potential global distribution of Q. gigas under current and future climate change scenarios (SSP2-4.5 and SSP5-8.5) for the years 2050, 2070, and 2090. The model exhibited excellent performance (AUC = 0.903, CBI = 0.868, TSS = 0.881), highlighting isothermality and precipitation of the wettest month as the main predictors, with relative contributions of 38.2% and 36.3%, respectively. However, the permutation importance analysis indicated that the coldest month's mean temperature was the most influential variable on the species' potential distribution, contributing to 56.7%. Currently, Q. gigas predominantly occupies tropical and subtropical regions of the Americas, with high climatic suitability in major coffee-producing areas, such as southeastern Brazil. Future projections indicate a progressive reduction in highly suitable areas, particularly under the SSP2-4.5 scenario, with estimated decreases of 3.55% by 2050, 4.28% by 2070, and 2.67% by 2090.

Regarding phytosanitary risks, the model identified potentially favorable climatic conditions in Africa, Asia, and Oceania.

Results demonstrated that the combination of α-CP with PN-Si-U achieved the highest control efficiency against adult B. zonata after 24, 48, and 72 h. Combinations of α-CP with PN-Si-U and α-CP with PN-T-U produced synergist ratios (SR) of 3.94 and 3.40, respectively (indicate the synergistic ratio of alpha-Cp alone). Further analysis revealed that α-CP (LC<sub>25</sub>) and α-CP synergized with PN, PN-T, or PN-Si-U significantly altered levels of acetylcholine esterase, carbohydrate-hydrolyzing enzymes (trehalase, amylase), total protein, protease, and kinase enzymes in adult B. zonata through 24-h exposure versus untreated controls. Treatments with activator adjuvants also affected reproductive potential (fecundity, fertility/hatchability, sterility index), oviposition periods (pre-oviposition, oviposition, post-oviposition), adult performance (longevity, emergence), larval duration, egg incubation period, and pupal parameters (pupal period, pupation). These findings suggest that adjuvant-enhanced formulations will promote the efficiency of the insecticide doses used, delay resistance development, and mitigate environmental pollution.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"55 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147691160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
