Modification of vector behavior is of broad adaptive significance, as parasite fitness relies on passage to a new host, and vector feeding is nearly always essential for transmission. Although several plant viruses infect their insect vectors, we have shown that vector infection by a plant virus alters feeding behavior. Here we show that infection with\n                    <jats:italic>Tomato spotted wilt virus<\/jats:italic>\n                    (TSWV), type member of the only plant-infecting genus in the\n                    <jats:italic>Bunyaviridae<\/jats:italic>\n                    , alters the feeding behavior of its thrips vector,\n                    <jats:italic>Frankliniella occidentalis<\/jats:italic>\n                    (Pergande). Male thrips infected with TSWV fed more than uninfected males, with the frequency of all feeding behaviors increasing by up to threefold, thus increasing the probability of virus inoculation. Importantly, infected males made almost three times more noningestion probes (probes in which they salivate, but leave cells largely undamaged) compared with uninfected males. A functional cell is requisite for TSWV infection and cell-to-cell movement; thus, this behavior is most likely to establish virus infection. Some animal-infecting members of the\n                    <jats:italic>Bunyaviridae<\/jats:italic>\n                    (\n                    <jats:italic>La Crosse virus<\/jats:italic>\n                    and\n                    <jats:italic>Rift Valley fever virus<\/jats:italic>\n                    ) also cause increased biting rates in infected vectors. Concomitantly, these data support the hypothesis that capacity to modify vector feeding behavior is a conserved trait among plant- and animal-infecting members of the\n                    <jats:italic>Bunyaviridae<\/jats:italic>\n                    that evolved as a mechanism to enhance virus transmission. Our results underscore the evolutionary importance of vector behavioral modification to diverse parasites with host ranges spanning both plant and animal kingdoms.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1100773108","type":"journal-article","created":{"date-parts":[[2011,5,24]],"date-time":"2011-05-24T00:31:06Z","timestamp":1306197066000},"page":"9350-9355","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":302,"title":["Infection with a plant virus modifies vector feeding behavior"],"prefix":"10.1073","volume":"108","author":[{"given":"Candice A.","family":"Stafford","sequence":"first","affiliation":[{"name":"Departments of aPlant Pathology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory P.","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Entomology, University of California, Riverside, CA 92521"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diane E.","family":"Ullman","sequence":"additional","affiliation":[{"name":"Entomology, University of California, Davis, CA 95616, and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2011,5,23]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ento.48.091801.112722"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.meegid.2007.05.008"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/283383a0"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.1977.0093"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.en.22.010177.000323"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.1998.0358"},{"key":"e_1_3_3_7_2","first-page":"93","article-title":"Studies on Trypanosoma rangeli Tejera, 1920 II.
