The fossil record of this subfamily includes five extinct species assigned to the extinct genus Prosolierius, discovered in Barremian-Cenomanian amber deposits from Lebanon, Spain, and northern Myanmar. Here we describe a new species of Solieriinae, Prosolierius qizhihaoi sp. nov., based on an exceptionally well-preserved specimen from the mid-Cretaceous Kachin amber. This new species exhibits close morphological similarities to Prosolierius thayerae Yamamoto, particularly in the elongation of antennomere 11 and the narrow genital segments. However, P. qizhihaoi can be distinguished by its elongate and slender antennomere 3, as well as the distinctly oval-shaped antennomere 4. The discovery of these fossil species within Prosolierius highlights the previously unrecognized palaeodiversity of Solieriinae rove beetles during the late Mesozoic, providing new insights into the evolutionary history of this enigmatic subfamily.</div><div>LSID code: www.zoobank.org/urn:lsid:zoobank.org:act:F1C95B5A-BD6D-4F84-9B03-8DD25CDFBAE2</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 2","pages":"Article 102405"},"PeriodicalIF":1.1,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758946","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}

Both species are present during the cotton seedling and budding stages, but as the flowering and boll-formation stage progresses, the aphid population rapidly declines, whereas the adult population of H. variegata often remains high for an extended period. To understand this phenomenon, we investigated the effects of feeding newly emerged H. variegata adults with cotton pollen and honey on their survival rate, lifespan, and reproductive capacity. The study found that pollen consumption in H. variegata adults varied significantly with age and sex, with females generally consuming more pollen than males, particularly at 10, 15, and 20 days of age. The aphid-fed group exhibited the longest lifespan (female 56.0 ± 1.8 d, male 60.1 ± 2.7 d), significantly surpassing those fed with cotton honey, collected from bees, (female 36.1 ± 2.2 d, male 31.7 ± 0.9 d) and pollen (female 12.2 ± 0.4 d, male 9.7 ± 0.8 d). While predation on aphids allowed H. variegata to produce 646.1 ± 14.6 eggs over a 30-d period (starting from the first oviposition), none of the adults fed with cotton pollen or honey laid eggs. Therefore, cotton pollen and honey play a positive role in maintaining the adult population of H. variegata in the field when aphids are absent but cannot support reproduction. Nevertheless, this maintenance effect benefits conservation biological control in cotton fields and effectively controls thrips and other pests at subsequent cotton growing stages.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 2","pages":"Article 102404"},"PeriodicalIF":1.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737912","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}

Thioredoxin peroxidases (TPXs) play critical roles in protecting insects from insecticide-induced oxidative injury. The black cutworm, Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae), is an important agricultural pest. Lambda-cyhalothrin (LCT) is a pyrethroid insecticide used to control A. ipsilon. However, whether LCT causes oxidative stress and whether TPXs are involved in the antioxidant defense in A. ipsilon remain unknown. In this study, a TPX gene, AiTPX6, was identified from A. ipsilon. AiTPX6 consists of five exons and four introns and encodes a protein of 227 amino acid residues. The AiTPX6 protein has characteristic features of TPXs, including the peroxidase active site motif PVCTTE with a conserved catalytic cysteine residue. Phylogenetic analysis revealed that AiTPX6 belongs to the “1-Cys” TPX group. The mRNA transcripts of AiTPX6 were most abundant in the larval midgut and at the fifth- and sixth-instar larval stages. Exposure to a sublethal concentration (LC50) of LCT significantly increased the H2O2 and malondialdehyde (MDA) concentrations and elevated the mRNA level of AiTPX6, suggesting that LCT-induced oxidative stress activates AiTPX6 transcription. Recombinant AiTPX6 expressed in Escherichia coli displayed potent antioxidant activity, protecting the cells against oxidative stress. Knockdown of AiTPX6 via RNA interference (RNAi) significantly increased the mortality rate of A. ipsilon following LCT exposure. These findings revealed that AiTPX6 contributes to LCT tolerance via antioxidant defense and could therefore be used as a potential target for RNAi-based control of A. ipsilon.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 2","pages":"Article 102403"},"PeriodicalIF":1.1,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143704595","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}

The results showed that FF exposure significantly inhibited the activity of key antioxidant enzymes, SOD, CAT, and TPX, in the midgut. Transmission electron microscopy revealed notable cellular damage, including microvilli shedding, chromatin aggregation, nuclear membrane depression, double membrane-bound vesicle autophagosomes, mitochondrial membrane rupture and swelling in the midgut after FF exposure. Furthermore, the oxidative phosphorylation pathway in the midgut was markedly suppressed, and the release of mitochondrial BmCytochrome c was significantly increased in the treatment group. The protein expression levels of BmCaspase-3 and cleaved BmCaspase-3 significantly were upregulated by 2.35-fold and 1.33-fold respectively, indicating the activation of the apoptotic signaling pathway. Additionally, TUNEL staining confirmed increased apoptotic signals in the midgut induced by FF.
