The presence or absence of abdominal hair tufts and the morphology of the mid tibiae (small, medium, or large) in males both represent major interspecific and intraspecific differences in this genus. In this study, we generated hybrids between two <i>Ostrinia</i> species (<i>O</i>. <i>furnacalis</i> and <i>O</i>. <i>scapulalis</i>) with different abdominal hair and mid-tibial phenotypes to explore their hereditary modes. The ratios of abdominal hair phenotypes in F2 and backcrossed individuals indicated that a single dominant locus on an autosome determines the presence of abdominal tufts in males. After 23 rounds of backcrossing to <i>O</i>. <i>furnacalis</i> (lacking abdominal tufts), where only individuals with abdominal tufts were selected as male parents in each generation, males with abdominal tufts also exhibited enlarged, grooved mid tibiae, whereas those without abdominal tufts did not. According to these results, the two traits are most likely governed by the same locus, or tightly linked genomic regions, in <i>Ostrinia</i> moths. This study is the first to clarify the genetic association between abdominal hair and mid-tibial traits, thus providing insights into understanding the evolution of a male-specific novelty in the genus.</p></div>","PeriodicalId":8551,"journal":{"name":"Applied Entomology and Zoology","volume":"60 3","pages":"183 - 190"},"PeriodicalIF":1.2,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13355-025-00907-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145142035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Argentine ants <i>Linepithema humile</i> Mayr (Hymenoptera: Formicidae), a globally invasive species, have been expanding their range in Japan since their first detection in 1993. This study attempted to detect four pathogenic viruses frequently detected in and may cause serious damage to the western honey bees <i>Apis mellifera</i> Linnaeus (Hymenoptera: Apidae) in Japan from Argentine ants invading managed hives of the honey bees. Quantitative PCR targeting four honey bee pathogenic DNA and RNA viruses detected <i>Apis mellifera</i> filamentous virus (AmFV) and black queen cell virus (BQCV) in Argentine ants attacking hives, with copy numbers ranging from 10¹–10² and 10³–10⁴, respectively. The copy number of deformed wing virus and sacbrood virus was below the detection limit. Homology searches of capsid protein-encoding genes and phylogenetic analysis revealed that all BQCV sequences from this study were most homologous to those previously identified in managed honey bees in Japan. However, AmFV sequences could not be obtained, likely due to the low copy number. These findings suggest that Argentine ants may act as a vector of AmFV and BQCV, raising concerns about their potential impact on the beekeeping industry.</p></div>","PeriodicalId":8551,"journal":{"name":"Applied Entomology and Zoology","volume":"60 3","pages":"221 - 227"},"PeriodicalIF":1.2,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145142584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the impact of vibrations on individual development in insects. Furthermore, previous studies of anthropogenic noise have been dominated by airborne sound, and studies of substrate-borne vibration are limited. Here, we investigated the effects of vibrations on egg hatching and larval development in the dark-winged fungus gnat, <i>Lycoriella ingenua</i> (Dufour, 1839) (Diptera: Sciaridae), which is a major pest of commercial mushrooms worldwide. Vibration at a frequency of 3000, 1000, 800, or 100 Hz with low- or high-acceleration treatment suppressed the emergence rate to almost zero. Emergence rate suppression was caused by increased early and late larval mortality at 3000 Hz vibration, whereas it was caused by increased early larval mortality at 100 Hz vibration, suggesting that the impact varied with the frequency. Hatch rate was suppressed only at 3000 Hz and with low acceleration, indicating that the impact of vibration was much higher on emergence rate than on hatch rate.
