The sensory biology and neuroanatomy of these insects are, however, poorly investigated. This research aims to describe the antennal sensilla of nymphs of the stonefly <em>Dinocras cephalotes</em> using scanning electron microscopy and comparing them with the adult sensilla. Besides, central antennal pathways in nymphs and adults are investigated by neuron mass-tracing with tetramethylrhodamine, and their brain structures are visualized with an anti-synapsin antibody. No dramatic changes occur in the antennal sensilla during nymphal development, while antennal sensilla profoundly change from nymphs to adults when switching from an aquatic to an aerial lifestyle. However, similar brain structures are used in nymphs and adults to process diverging sensory information, perceived through different sensilla in water and air. These data provide valuable insights into the evolution of aquatic heterometabolous insects, maintaining a functional sensory system throughout development, including a distinct adaptation of the peripheral olfactory systems during the transition from detection of water-soluble chemicals to volatile compounds in the air. From a conservation biology perspective, the present data contribute to a better knowledge of the biology of stoneflies, which are very important bioindicators in rivers.</p></div>","PeriodicalId":55461,"journal":{"name":"Arthropod Structure & Development","volume":"79 ","pages":"Article 101345"},"PeriodicalIF":2.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S146780392400015X/pdfft?md5=2940c34d1c1ae0e818fcb23fa8e295f7&pid=1-s2.0-S146780392400015X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140141697","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}

It produces a cocktail of monoterpenes in soldiers, and some of these monoterpenes and unidentified proteins in workers. The labral and labial glands are developed similarly to other termite species and contribute to defensive activities (labral in both castes, labial in soldiers) or to the production of digestive enzymes (labial in workers).

Larvae of <em>E. lyneborgi</em> were found in a decaying stem of <em>Cyphostemma juttae</em> (Dinter &amp; Gilg) Desc., 1960 (Vitaceae) in Namibia (Africa), while larvae of <em>M. constans</em> were collected in bulbs of <em>Leucojum vernum</em> Linnaeus, 1753, (Amaryllidaceae) in France (Europe). Morphology of the immature forms was studied by observation and imaging with stereomicroscopy and scanning electron microscopy. The head skeleton of <em>E. lyneborgi</em> larvae was found to be of the filter feeding type, i.e., in accordance with a saprophagous trophic regime, while that of <em>M. constans</em> was typically phytophagous. Variability in certain characters of the <em>M. constans</em> early stages is described and discussed in relation to the adult form and molecular information published in literature. An updated identification key to all known third larval stages/puparia of <em>Merodon</em> is provided.</p></div>","PeriodicalId":55461,"journal":{"name":"Arthropod Structure & Development","volume":"78 ","pages":"Article 101328"},"PeriodicalIF":2.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1467803923000956/pdfft?md5=450076ad2cc6da6220560582feda6f04&pid=1-s2.0-S1467803923000956-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139063542","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}
