Status: <\/strong><\/h5>\n<p><strong><u>Background:<\/u><\/strong> <em>\u00a0<\/em>Adult <em>R. cruentatus<\/em> are large weevils that measure 2.7 to 3.3 centimeters in length (Wattanapongsiri, 1966).\u00a0 They are dull to shining and reddish-brown to black (or a pattern of both) in color (Giblin-Davis et al., 1994).\u00a0 This species attacks palms.\u00a0 Eggs are laid in petiole bases or wounds in the palm.\u00a0 The larvae feed on the tissue internally and form a cocoon made from plant fiber, in which they pupate.\u00a0 The feeding damage can compromise the structural integrity of the palm to the extent that the crown falls over (Giblin-Davis and Howard, 1988).\u00a0 The larval feeding damage is cryptic because it occurs inside the palm, and it is often not apparent until death of the tree is inevitable (Hunsberger et al., 2000).\u00a0 In the case of <em>Sabal palmetto<\/em>, which is native in the beetle\u2019s area of distribution, <em>R. cruentatus<\/em> apparently only attacks stressed trees.\u00a0 However, in the case of introduced palm species, including <em>Phoenix canariensis<\/em>, apparently healthy trees are attacked and killed, sometimes in large numbers. \u00a0For example, 97% of the <em>Phoenix canariensis<\/em> in one Florida nursery were killed; the damage was estimated at $285,000-$380,000 (Hunsberger et al., 2000). \u00a0Besides <em>Phoenix<\/em> and <em>Sabal<\/em>, other genera of palms reported to be attacked include <em>Caryota<\/em>, <em>Cocos<\/em>, <em>Latania<\/em>, <em>Pritchardia<\/em>, <em>Roystonea<\/em>, <em>Thrinax<\/em>, and <em>Washingtonia<\/em> (Hunsberger et al., 2000; Weissling and Broschat, 1999). \u00a0Other non-palm plants may also be utilized by this beetle, but little information is available regarding this (Wattanapongsiri, 1966).<\/p>\n<p>Other <em>Rhynchophorus<\/em> species are important palm pests, for example <em>R. ferrugineus<\/em> and <em>R. palmarum<\/em>.\u00a0 <em>Rhynchophorus palmarum<\/em> is a vector of the nematode <em>Bursaphelenchus cocophilus<\/em>, which causes red ring disease of palms.\u00a0 This nematode is not yet known to occur in the United States.\u00a0 The disease affects <em>Phoenix dactylifera<\/em> and <em>P. canariensis<\/em>, which are important crop and ornamental trees in California (Hodel, 2016).\u00a0 If this nematode was introduced to the United States, <em>R. cruentatus<\/em> could possibly vector it (Griffith, 1987).<\/p>\n<p><strong><u>Worldwide Distribution<\/u><\/strong><strong><u>:<\/u><\/strong>\u00a0 <em>Rhynchophorus cruentatus<\/em> is native to the southeastern United States and is found from South Carolina south to Florida (including the Florida Keys) and west to Texas.\u00a0 The species has also been reported from the Bahamas (Andros Island), which may represent an introduction (Turnbow and Thomas, 2008;
