Matsunaga, pers. comm.).\u00a0 This species is considered a pest of sugarcane.\u00a0 The larvae bore into and feed in the stalks of the plant (Magarey et al., 2002).\u00a0 However, some reports suggest it is of minor significance.\u00a0 For example, it is reported to primarily attack sugar cane that is damaged or weak in Fiji (Imperial Bureau of Entomology, 1920).\u00a0 The beetle has been reported to attack coconut palm; details on the damage inflicted are sparse, but one report suggests this beetle may provide conditions allowing other, more serious pests to attack trees (Corbett 1932).\u00a0 This species was also reported to be associated with, and possibly damage bananas, although no further details were found (Harmer, 1912; Mararuai, 2010).\u00a0 Lastly, this species is apparently often found associated with dead palm trees (J. Matsunaga, pers. comm.).<\/p>\n<p><strong><u>Worldwide Distribution<\/u><u>:<\/u><\/strong>\u00a0 <em>Trochorhopalus strangulatus <\/em>is known from islands in the Indian Ocean (Republic of Seychelles and the Mascarene Islands), Southeast Asia (Indonesia and Philippines), Papua New Guinea, Fiji, and Hawaii (Hustache, 1920; Magarey et al., 2002; J. Matsunaga, pers. comm.; Pemberton, 1963; Senterre et al., 2011; Symbiota Collections of Arthropods Network).\u00a0 The native distribution is unknown, although one report states it is indigenous to the Seychelles (Senterre et al., 2011).\u00a0 The distribution has presumably been expanded as a result of cultivation and transport of sugarcane in Southeast Asia and Pacific islands, which began thousands of years ago, and it is assumed that at least some localities represent introductions (Artschwager and Brandes, 1958).<\/p>\n<p><strong><u>O<\/u><u>fficial Control:<\/u> <\/strong><em>Trochorhopalus strangulatus <\/em>is not known to be under official control anywhere.<\/p>\n<p><strong><u>California Distribution: <\/u><\/strong>\u00a0<em>Trochorhopalus strangulatus<\/em> is not known to occur in California.<\/p>\n<p><strong><u>California Interceptions:<\/u><\/strong>\u00a0 <em>Trochorhopalus strangulatus<\/em> has not been intercepted in California.<\/p>\n<p>The risk <em>Trochorhopalus strangulatus <\/em>w<em>o<\/em>uld pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:<\/strong><\/h5>\n<p><strong>1) Climate\/Host Interaction:<\/strong> <em>Trochorhopalus strangulatus<\/em> has been reported to feed on sugarcane, banana, and palms. Of these, ornamental palms are the most obvious possible host plant in California, and they are present throughout much of the state. \u00a0Based on the current distribution of <em>T. strangulatus<\/em> (tropical areas), it appears unlikely that this species could become established in more than a very limited portion of California.\u00a0 Therefore, this species receives a <span style=\"color: #008000;\"><strong>Low (1)<\/strong><\/span> in this category.<\/p>\n<p style=\"padding-left: 30px;\"><span style=\"color: #008000;\">\u2013 <strong>Low (1)<\/strong> Not likely to establish in California; or likely to establish in very limited areas.<\/span><\/p>\n<p style=\"padding-left: 30px;\">\u2013 Medium (2) may be able to establish in a larger but limited part of California.<\/p>\n<p style=\"padding-left: 30px;\">\u2013 High (3) likely to establish a widespread distribution in California.<\/p>\n<p><strong>2) Known Pest Host Range: <\/strong><em>Trochorhopalus strangulatus<\/em> is a pest of sugar cane, but has also been reported to attack coconut palm and bananas, which suggests at least three families of plants are fed upon. Unfortunately, details regarding feeding on these alternate host plants are lacking. Therefore, <em>T. strangulatus<\/em> receives a <span style=\"color: #008000;\"><strong>Medium (2)<\/strong> <\/span>in this category.<\/p>\n<p style=\"padding-left: 30px;\">\u2013 Low (1) has a very limited host range.<\/p>\n<p style=\"padding-left: 30px;\"><span style=\"color: #008000;\">\u2013 <strong>Medium (2)<\/strong> has a moderate host range.<\/span><\/p>\n<p style=\"padding-left: 30px;\">\u2013 High (3) has a wide host range.<\/p>\n<p><strong>3) Pest Dispersal Potential:<\/strong> <em>Trochorhopalus strangulatus <\/em>presumably flies.\u00a0 Therefore, it receives a <span style=\"color: #008000;\"><strong>Medium (2)<\/strong> <\/span>in this category.<\/p>\n<p style=\"padding-left: 30px;\">\u2013 Low (1) does not have high reproductive or dispersal potential.<\/p>\n<p style=\"padding-left: 30px;\"><span style=\"color: #008000;\">\u2013 <strong>Medium (2)<\/strong> has either high reproductive or dispersal potential.<\/span><\/p>\n<p style=\"padding-left: 30px;\">\u2013 High (3) has both high reproduction and dispersal potential.<\/p>\n<p><strong>4) Economic Impact:<\/strong> This weevil is a pest of sugarcane and it has also been reported to attack banana and palms.\u00a0 California industries that could be affected by the establishment of this weevil include ornamental palms and sugarcane.\u00a0 Ornamental palms are a $70 million industry in California, and damage (including lowering of yield) to palms in nurseries could result if <em>T. strangulatus<\/em> became established in California (Hoddle).\u00a0 Sugarcane is either currently being grown in, or is planned to be grown in the Imperial Valley, where a sugarcane-based sugar and biofuels initiative is underway.\u00a0 If this weevil became established in the Imperial Valley, which may not be likely given its apparent restriction to tropical areas, it could lower yield of sugarcane there.\u00a0 An extensive sugarcane industry exists in the southeastern United States, and the climate in that region would likely be more favorable for the establishment of this pest.\u00a0 The possibility of the spread of this pest to the southeastern United States (and impact on sugarcane and palms there), as well as other countries, could lead to a loss of markets for ornamental palms from California. \u00a0Therefore, <em>T. strangulatus<\/em> receives a <strong><span style=\"color: #008000;\">Medium (2)<\/span><\/strong> in this category.<\/p>\n<p><strong>Economic Impact: <span style=\"color: #008000;\">A, C<\/span><\/strong><\/p>\n<p style=\"padding-left: 30px;\"><span style=\"color: #008000;\"><strong>A<\/strong>.
