Blocking the anus or the dorsal surface with wax does not prevent water vapor uptake, but interference with movements of the mouthparts or blocking the mouth with wax-prevents such uptake. Weight gains are associated with the protrusion from the mouth of two bladder-like extensions of the hypopharynx. During absorption these structures are warmer than the surrounding mouthparts, their surface temperature increasing with relative humidity. This suggests that the surfaces of the bladder-like structures function at least as sites for condensation of water vapor, but the precise location of its transfer into the hemolymph has not yet been identified.<\/jats:p>","DOI":"10.1073\/pnas.74.4.1757","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T03:29:46Z","timestamp":1149046186000},"page":"1757-1760","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":34,"title":["Site of water vapor absorption in the desert cockroach, Arenivaga investigata."],"prefix":"10.1073","volume":"74","author":[{"given":"M J","family":"O'Donnell","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[1977,4]]},"container-title":["Proceedings of the National Academy of Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pnas.org\/doi\/pdf\/10.1073\/pnas.74.4.1757","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T11:11:54Z","timestamp":1649848314000},"score":1,"resource":{"primary":{"URL":"https:\/\/pnas.org\/doi\/full\/10.1073\/pnas.74.4.1757"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1977,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1977,4]]}},"alternative-id":["10.1073\/pnas.74.4.1757"],"URL":"https:\/\/doi.org\/10.1073\/pnas.74.4.1757","relation":{},"ISSN":["0027-8424","1091-6490"],"issn-type":[{"value":"0027-8424","type":"print"},{"value":"1091-6490","type":"electronic"}],"subject":[],"published":{"date-parts":[[1977,4]]},"assertion":[{"value":"1977-04-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
