Dung beetles (Coleoptera: Scarabaeinae) act as bioindicators and ecosystem engineers, notably by mediating secondary seed dispersal and promoting soil bioturbation. We investigated taxonomic and functional attributes of dung beetle communities and quantified seed-removal rates in a severely degraded site (topsoil removal for dam construction) and in an adjacent, less-disturbed reference area within the Brazilian Cerrado. Contrary to our initial predictions, in the degraded site hosted higher species richness (27 vs. 26 species), greater abundance (5371 vs. 1142), and higher functional richness (FRic), whereas functional divergence (FDiv) was greater in the reference area. Community-weighted means (CWMs) for traits associated with excavation and rolling (pronotum volume, front-leg area, and hind-to-front leg length ratio) were significantly elevated in the degraded area, despite a lower mean body mass. Seed-removal rates were also significantly higher in the degraded site. Across the dataset, seed removal correlated positively with FRic, abundance, pronotum volume, front-leg area, and hind/front leg ratio, and negatively with FDiv and body mass; however, these relationships were context-dependent and largely vanished when habitats were analysed separately. Our results indicate that the dung beetle assemblage colonizing the degraded site is dominated by abundant, morphologically specialized species that can sustain high rates of seed removal despite low functional divergence. We discuss implications for restoration: the presence of functionally competent, abundant dung beetles can facilitate secondary seed dispersal in heavily degraded landscapes, but reliance on a few trait-dominant species may render this service vulnerable to further perturbation.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"55 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13473256/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148762308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adult worker bees were exposed to this bioinsecticide by contact and ingestion at concentrations recommended for strawberry crops, and mortality was assessed after 24, 48, and 72 h. Morphological alterations of the midgut and changes in chromatin structure in brain cells were evaluated in the surviving stingless bees. Exposure resulted in low mortality, precluding the estimation of the LC₅₀, but revealed significant sublethal effects, such as disorganization of the midgut epithelium, loss of digestive cells, reduction of regenerative cells, and disappearance of the peritrophic membrane. An increase in chromatin condensation was detected at different exposure times and concentrations, suggesting disruption of gene regulatory processes. These findings indicate that although azadirachtin does not induce immediate lethality in N. testaceicornis, it may compromise digestive physiology and genomic integrity, potentially affecting individual performance and long-term colony maintenance. The results highlight the importance of considering sublethal parameters in bioinsecticide risk assessments, as they may reveal hidden and ecologically relevant impacts that are not detected by mortality alone.

The established models demonstrated strong reliability and accuracy, with an average AUC of 0.903, a mean TSS of 0.705, and only 17.08% of the total suitable habitats classified as extrapolation areas.

The current potential distribution of this pest mainly concentrated in North America, South America, Africa, Oceania, and Asia. Under future climate scenarios, the suitable habitats of F. virgata exhibited divergent invasion risks, and low-emission climate pathways could constrain the pest's long-term suitable ranges. We put forward three targeted strategies for prevention and control, existing-area governance, forward-looking early warning, and cross-regional coordinated prevention.

However, these discussions are often limited to a few specific case studies. Large-scale region-wide evaluations of risks and benefits of releases of natural enemies are rare. We tracked the names of 1099 biocontrol agents used in arthropod biocontrol in Latin America and the Caribbean, and ranked them according to origin (native or exotic), to their role in pest reduction (significant or not) and negative non-target effects. About 40% of the agents used in this region were of exotic origin. Depending on the type of programme-natural, conservation, classical or augmentative biocontrol-the percentages of natural enemies attaining significant pest reduction were 40 up to 100. Hence, many natural enemies provided benefits in the form of healthy, sustainable and environmentally friendly pest management. The documented risk associated with the use of exotic natural enemies appears to be low, although minor or poorly monitored non-target effects may have gone undetected. In order to limit occurrence of negative non-target effects in the future, first an inventory should be made of native natural enemies including an assessment of whether one or more of these species are able to sufficiently reduce pest populations.

In addition, we propose a standardized and replicable rearing protocol for D. luteipes, which involves the use of acrylic straws as oviposition substrates and shelters, corrugated cardboard as a structural refuge, and the provision of a nutritionally adequate artificial diet for both nymphs and adults. The described method indicates to be suitable not only for rearing D. luteipes but also for other species within the order Dermaptera.
