To gather more evidence of their existence, cuticular liposoluble extracts were obtained from the following samples of adult females to be used as the experimental treatments: (1) ventral exoskeleton of immature female (VI), (2) dorsolateral exoskeleton of immature female (DI), (3) ventral exoskeleton of mature female (VM), and (4) dorsolateral exoskeleton of mature female (DM). Polyvinyl chloride tubes (artificial females; AF) were coated with each extract and the behavior displayed by sexually mature males in contact with the AF was recorded and classified as follows: 0 = no response; 1 = contact; 2 = pushing; and 3 = prolonged contact (\u226510 s). To test the hypothesis that the extracts collected from the ventral portion of the abdomen exoskeleton have a higher effect on the behavior of males than the extracts collected from the dorsolateral portion of the abdomen exoskeleton, the experiment was divided into two bioassays: Bioassay I (VI vs. DI) and Bioassay II (VM vs. DM). In each bioassay, all experimental treatments were significantly different (p &gt; 0.05) from the CTL group (AF coated with hexane). Notably, the pushing behavior was significantly higher (p &lt; 0.05) in the VI treatment compared to the CTL and DI treatment. These results provide evidence of the existence of contact female sex pheromones with sexual recognition function located primarily in the ventral portion of the abdomen exoskeleton of P. vannamei.<\/jats:p>","DOI":"10.3390\/ani14111523","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T06:54:09Z","timestamp":1716360849000},"page":"1523","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Evidence of the Existence of Site-Specific Female Contact Pheromones Involved in the Sexual Interaction Behavior of the Pacific Whiteleg Shrimp Penaeus\u00a0vannamei"],"prefix":"10.3390","volume":"14","author":[{"given":"Jos\u00e9 A.","family":"Guti\u00e9rrez-Vera","sequence":"first","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Baja California (CICESE), Ensenada 22860, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2842-7300","authenticated-orcid":false,"given":"Elizabeth","family":"Ponce-Rivas","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Baja California (CICESE), Ensenada 22860, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7579-4472","authenticated-orcid":false,"given":"Andr\u00e9","family":"Braga","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Oceanol\u00f3gicas, Universidad Aut\u00f3noma de Baja California, Ensenada 22873, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen G.","family":"Paniagua-Ch\u00e1vez","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Baja California (CICESE), Ensenada 22860, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Alfaro-Montoya","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n de Biolog\u00eda Marina, Escuela de Ciencias Biol\u00f3gicas, Universidad Nacional, Puntarenas 86-3000, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0279-6471","authenticated-orcid":false,"given":"Misael","family":"Rosales-Leija","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Baja California (CICESE), Ensenada 22860, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,22]]},"reference":[{"key":"ref_1","unstructured":"FAO (2022).
