Previous studies have shown that mitogenomes often produce ambiguous phylogenetic topologies that are inconsistent with both morphological and multi-locus molecular data. In this study, we sequenced 18 new mitogenomes representing 5 subfamilies, including the first available sequence for Protanypodinae. These were combined with 65 previously annotated chironomids mitogenomes, 8 additional individuals assembled from SRA data, and 8 outgroup taxa. Phylogenetic reconstructions were performed using complete protein-coding genes (PCGs), the first and second codon positions of PCGs (PCG 12), with and without ribosomal genes (12S rDNA and 16S rDNA), and amino acid sequences (AA). Both Bayesian Inference and Maximum Likelihood approaches were implemented. Three alternative outgroup compositions were tested: (i) chironomids only, with restricted rooting on Podonominae; (ii) Ceratopogonidae and Culicidae; and (iii) a diverse selection of Culicomorpha. We found that the AA, PCG12, and PCG 12 + rDNA datasets, when coupled with the third outgroup combination, provide the strongest phylogenetic signal, with the highest effective sample size and log-likelihood scores. In most cases, the resulting tree topologieswere congruent between mitochondrial and multi-locus data. However, some consistent differences in topologies were observed, leading to differences in divergence time estimates. Our phylogenetic study indicates paraphyly of Orthocladiinae due to the positions of Brillia Kieffer and Abiskomyia Edwards, suggesting that a comprehensive integrative revision of this subfamily is required. We conclude that the reliability of the mitochondrial phylogenetic signal improves with the increased taxon sampling.</p>","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"25 4","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12260381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144637225","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}

This coincides with some of the characteristics reported in 1933 for the species Moluchia brevipennis (Saussure, 1864) (Blattellidae). However, the internal genital morphology suggests that these correspond to at least three species. Here, we studied these morphological features using classical dissection techniques and SEM. Based on this, we redescribed the male of M. brevipennis, the female, and the ootheca, which was previously unknown. In the same way, we assign a lectotype from Saussure's original material. In addition, we describe two new species: Moluchia akelarre Schapheer, Villagra, and Vera sp. nov. and Moluchia kuyen Schapheer, Villagra, and Vera sp. nov. Finally, we reconstruct the geographic distribution of the three species and their association with the plant strata of the Mediterranean climate zone of Chile.

Stressed trees emit ethanol, which is the primary host-locating cue for ambrosia beetles. This study evaluated the efficacy of low-cost ethanol detectors as a solution for the early detection of flood-stressed trees susceptible to ambrosia beetle infestation. Experiments were conducted using 48 native dogwoods (Cornus florida L.) subjected to flooded or non-flooded conditions. The attacks of ambrosia beetles were significantly higher in flooded trees, indicating a clear preference and validating the use of flood stress as a reliable method for susceptibility assessment. Ethanol emitted from these trees was measured using low-cost alcohol saliva test strips and Dräger Pac 8000 personal gas detectors alongside a solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) for ethanol confirmation. In addition to stem tissue analysis for ethanol detection via SPME-GC-MS, we found that twig and root tissue samples can also be assessed effectively using low-cost detectors such as alcohol strips and Dräger devices. GC-MS, a reliable method for volatile compound identification and quantification, confirmed ethanol as the dominant volatile in flooded trees, with both low-cost detectors correlating positively with SPME-GC-MS results. These detectors could offer a rapid, cost-effective method for identifying trees at risk of ambrosia beetle attack. However, their accuracy can be limited by false positives, as some plant genera emit aromatic volatiles such as eugenol, which may interfere with ethanol detection.

Several recent studies have shown that traps can be improved by systematically considering properties of color vision for the target species. In the current study, we extend this approach to spatial vision, using information about the interommatidial angle of an agriculturally important insect pest, western flower thrips Frankliniella occidentalis (Pergande), to predict spatial resolution capabilities for a yellow flower pattern across a range of viewing distances. We tested the hypothesis that pattern sizes matching the spatial resolution capabilities of western flower thrips at a given viewing distance would outperform traps with mismatched pattern sizes by measuring the number of western flower thrips caught on sticky traps containing differently sized flower patterns resolvable at 5, 10, or 20 cm. We found an interaction between pattern size and viewing distance, with significantly more western flower thrips caught on traps when the predicted resolvable distance of the pattern matched the distance traps were placed from a central release point. We further tested the range over which trap patterns are effective in more complex viewing environments using commercial polytunnels. In polytunnel trials, we found that increasing the resolvable distance of patterns increased western flower thrips capture up to approximately 26 cm, after which western flower thrips capture decreased up to the maximal visible range tested (50 cm) in the absence of additional sensory cues. Together, these results show the utility of considering spatial vision in improving trap performance and offers functional insights to improve pest management in visual trap design.</p>","PeriodicalId":16156,"journal":{"name":"Journal of Insect Science","volume":"25 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12070478/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024181","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}
