Terbufos (organophosphate) stands out in the forensic field for its association with intoxication cases. However, the methodologies for its detection remain laborious, expensive, and destructive for crime clues, with the need for simpler, accessible, and conservative tools for detection of this compound in the entomological evidence. Thus, this study aims to evaluate (i) Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) as a tool to differentiate larvae collected from negative control carcasses and those treated with terbufos and (ii) the overall sensitivity and specificity of the technique for identifying terbufos exposure in forensic contexts, discussing its applicability in real cases of organophosphate poisoning. For this, Lucilia eximia (Diptera: Calliphoridae) larvae (n = 120; 30/group), collected from rat carcasses previously treated with 5 (T1), 10 (T2), or 20 (T3) mg/kg of terbufos, as well as from untreated control carcasses (negative control-NC), were used for spectra collection and standardization of classification model. For data analysis, differentiation, and classification, unsupervised (PCA) and supervised (PCA-LDA, GA-LDA, and SPA-LDA) analysis algorithms were used. The PCA showed a tendency of differentiation between the analyzed groups. However, only with the supervised analysis algorithms, spectra from the negative control, T1, T2, and T3 groups were differentiated. The PCA-LDA and SPA-LDA algorithms specially differentiated the T3, T2, and NC groups, reaching an average 85% sensitivity and 90% specificity, while the GA-LDA showed 100% sensitivity and specificity, being the model of choice for analyzing this dataset. The main variables listed for sample differentiation were in the regions of protein phosphorylation, phosphate stretch, and protein content. Thus, this study showed that the ATR-FTIR coupled with multivariate analysis algorithms can efficiently differentiate larvae collected from carcasses non-intoxicated or intoxicated with different doses of terbufos, representing a viable, fast and efficient screening alternative for entomotoxicology.</p>","PeriodicalId":19071,"journal":{"name":"Neotropical Entomology","volume":"55 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13538237/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148880918","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}

Some species, such as Pseudohypocera kerteszi (Enderlein, 1912), are economically important due to their negative effects on stingless bee colonies. Chemical ecology plays an important role in understanding these interactions, as compounds like cuticular hydrocarbons and mandibular secretions function as semiochemicals guiding host recognition and influencing parasite behavior. However, studies addressing chemical mechanisms remain relatively limited. This review systematically synthesizes data on parasite-host interactions in Phoridae, integrating behavioral and chemical perspectives.

Ten species of Araceae belonging to the genera Dieffenbachia (1), Philodendron (5), Syngonium (3) and Xanthosoma (1) were investigated. A total of 334 infructescences were sampled, of which only 5.1% were found to be infested by ants.

Our results provide evidence that ants use aroid infructescences as nesting sites. The ant colony structure was highly variable, suggesting that aroids may be used by ants to establish colonies, as temporary polydomous colonies, and to gather prey as a food resource. Most of the ant species found are predators or omnivores and may benefit from the diverse endophagous insects that feed in these structures, as well as from their waste products.

Hyperspectral imaging offers a rapid and non-destructive alternative for evaluating parasitism. Therefore, this study aimed to discriminate Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae) pupae parasitized by Diachasmimorpha longicaudata (Ashmead, 1905) (Hymenoptera: Braconidae) using hyperspectral imaging and identifying the most informative spectral ranges and wavelengths for this purpose. Hyperspectral images were acquired from pupae at different developmental stages expressed in degree days (DD), preserving insect viability. Principal component analysis (PCA) and clustering analysis indicated a tendency to separate parasitized from non-parasitized pupae. Spectral profiles showed lower reflectance in the visible region and higher reflectance in the near-infrared (NIR, > 700 nm) for parasitized pupae. Greater spectral variability was also observed throughout development, particularly at 7 and 12 days (135 and 189 DD, respectively), compared with non-parasitized pupae at the same chronological ages (260.1 and 321.3 DD, respectively), which exhibited a more homogeneous spectral pattern. The Random Forest model showed moderate classification performance across all developmental stages, with higher predictive accuracy at later stages.

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}
