Tachinid flies are parasitoids of terrestrial arthropods, mostly insects, during their larval stage. To obtain oxygen while living in the host body, they build a cylindrical structure known as the respiratory funnel at the aperture opened by the tachinid larva on the host integument or trachea. These funnels can be divided morphologically into sheath and cone types. Previous research on sheath-type funnels revealed that they are derived from the encapsulating substance produced by the host's immune system. In contrast, the cone-type funnels cover part of the body of the larval tachinid and may be constructed independently from the host immune system. To determine the mechanisms of cone-type funnel formation, histological observations were carried out on <jats:italic>Gymnosoma rotundatum</jats:italic> (L.) (Diptera: Tachinidae), which possesses this type of funnel. The respiratory funnel of <jats:italic>G. rotundatum</jats:italic> was found to be derived from the tube-shaped faeces wrapped with the peritrophic membrane and excreted by the fly larva, not from host tissue or haemocytes. Additionally, secretory glands putatively involved in the funnel formation were discovered around the larval anal plate of <jats:italic>G. rotundatum</jats:italic>. A comparison of funnel types within Tachinidae revealed that Phasiinae and Dexiinae have cone-type funnels, which may be created by the same mechanism as in <jats:italic>G. rotundatum</jats:italic>. These new findings suggest that funnel formation that does not use the host immune system is relevant to tachinid phylogeny.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":"110 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614455","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 molecular chaperones encoded by small heat shock proteins (sHsps) are essential for rapid, appropriate responses to environmental stress. This study focuses on <i>Hsp20.8</i>, which encodes a temperature-responsive <i>sHsp</i> in <i>Liriomyza trifolii</i>, an insect pest that infests both agricultural and ornamental crops. <i>Hsp20.8</i> expression was highest at 39℃ in <i>L. trifolii</i> pupae and adults, and expression levels were greater in pupae than in adults. Recombinant <i>Hsp20.8</i> was expressed in <i>Escherichia coli</i> and conferred a higher survival rate than the empty vector to bacterial cells exposed to heat stress. RNA interference experiments were conducted using <i>L. trifolii</i> adults and prepupae and the knockdown of <i>Hsp20.8</i> expression increased mortality in <i>L. trifolii</i> during heat stress. The results expand our understanding of <i>sHsp</i> function in <i>Liriomyza</i> spp. and the ongoing adaptation of this pest to climate change. In addition, this study is also important for predicting the distribution of invasive species and proposing new prevention and control strategies based on temperature adaptation.</p>","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"230-236"},"PeriodicalIF":1.9,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140109181","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}
