To test whether or not <jats:italic>M. turgidus<\/jats:italic> has an effect on intermediate host behaviour, the length of time spent swimming and walking over 1min and 3min intervals and prey (<jats:italic>Artemia<\/jats:italic>) capture rates of uninfected grass shrimp and those infected with 1\u201310, 11\u201320 or 21\u201330 metacercarial cysts were compared. Uninfected shrimps spent significantly more time swimming than infected shrimps during the first minute of observation. There were no differences between the control and infected groups in terms of swimming at 3min, walking at 1 and 3min, or in numbers of prey captured. These results indicate that <jats:italic>M. turgidus<\/jats:italic> may induce little or no change in grass shrimp locomotion nor in prey capture behaviour. This is in contrast to other parasites that modify intermediate host behaviour to enhance their transmission to definitive hosts. Furthermore, these data support earlier studies indicating that <jats:italic>M. turgidus<\/jats:italic> does not affect the growth and survival of <jats:italic>P. pugio<\/jats:italic>.<\/jats:p>","DOI":"10.1079\/joh2003192","type":"journal-article","created":{"date-parts":[[2004,2,26]],"date-time":"2004-02-26T22:45:03Z","timestamp":1077835503000},"page":"327-330","source":"Crossref","is-referenced-by-count":6,"title":["Effects of the trematode <i>Microphallus turgidus<\/i> on locomotion and prey capture in the grass shrimp <i>Palaemonetes pugio<\/i>"],"prefix":"10.1017","volume":"77","author":[{"given":"R.N.","family":"Khan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.A.","family":"Spiers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"O.J.","family":"Pung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"S0022149X00702616_ref010","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8649.1994.tb01085.x"},{"key":"S0022149X00702616_ref003","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-0981(99)00084-2"},{"key":"S0022149X00702616_ref004","first-page":"81","article-title":"Life cycles of Carneophallus choanophallus n. sp. and C. basodactylophallus n. sp.
