Naturally occurring chiggers recovered from<jats:italic>Rattus losea<\/jats:italic>and<jats:italic>Bandicota indica<\/jats:italic>were 1\u00b74x and 1\u00b73x as engorged as those from<jats:italic>Apodemus agrarius<\/jats:italic>. Within each host species, RDE was negatively related to chigger loads, but was mostly unrelated to gender or to body or reproductive condition of hosts. We documented significant variation in chigger engorgement both within and among host species; to the extent that RDE is a proxy for fitness, this contradicts predictions of the Ideal Free Distribution (IFD) that the<jats:italic>per capita<\/jats:italic>fitness of vectors should be similar among hosts. Failure to meet predictions of the IFD may reflect the limited mobility of chiggers, which consequently must be less selective in the hosts on which they feed. Further disease control efforts should consider vector feeding success in addition to vector abundance and may be able to capitalize on the unsuitability of certain hosts in supporting disease vectors.<\/jats:p>","DOI":"10.1017\/s003118201000140x","type":"journal-article","created":{"date-parts":[[2010,10,15]],"date-time":"2010-10-15T11:05:19Z","timestamp":1287140719000},"page":"344-353","source":"Crossref","is-referenced-by-count":10,"title":["Variation within and among host species in engorgement of larval trombiculid mites"],"prefix":"10.1017","volume":"138","author":[{"given":"C.-C.","family":"KUO","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.-C.","family":"WANG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.-L.","family":"HUANG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2010,10,15]]},"reference":[{"key":"S003118201000140X_ref33","doi-asserted-by":"publisher","DOI":"10.1093\/jmedent\/35.5.639"},{"key":"S003118201000140X_ref29","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182004004925"},{"key":"S003118201000140X_ref26","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2028.1993.tb00515.x"},{"key":"S003118201000140X_ref20","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2435.2005.01015.x"},{"key":"S003118201000140X_ref19","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2435.2008.01393.x"},{"key":"S003118201000140X_ref18","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.029389"},{"key":"S003118201000140X_ref17","doi-asserted-by":"publisher","DOI":"10.2307\/5786"},{"key":"S003118201000140X_ref16","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182099005442"},{"key":"S003118201000140X_ref15","doi-asserted-by":"publisher","DOI":"10.1016\/S1471-4922(01)02116-X"},{"key":"S003118201000140X_ref14","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2009.1159"},{"key":"S003118201000140X_ref13","volume-title":"Tsutsugamushi Disease: an Overview","author":"Kawamura","year":"1995"},{"key":"S003118201000140X_ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s00442-007-0851-7"},{"key":"S003118201000140X_ref7","doi-asserted-by":"publisher","DOI":"10.1644\/06-MAMM-F-185R1.1"},{"key":"S003118201000140X_ref6","doi-asserted-by":"publisher","DOI":"10.1007\/BF01601953"},{"key":"S003118201000140X_ref3","volume-title":"Parasitism: the Ecology and Evolution of Intimate Interactions","author":"Combes","year":"2001"},{"key":"S003118201000140X_ref2","unstructured":"CDC, Centers for Disease Control, Taiwan.
