PEST RATING PROFILE<\/h3>\n

Initiating Event:<\/h5>\n

Rubrocuneocoris calvertae<\/em> was reported to be established on Hawaii and Oahu islands, Hawaii (Henry, 2017; J. Matsunaga, pers. comm.).\u00a0 It is currently Q-rated, and a permanent pest rating proposal is required to support an official pest rating.<\/p>\n

History & Status:<\/h5>\n

Background:<\/u><\/strong> \u00a0Rubrocuneocoris calvertae <\/em>is a small plant bug (approximately 2.5 millimeters in length) that is dull brown in color except for distinctive red markings on the posterior portion of the forewings (a character shared with other members of the genus).\u00a0 This species is only known from Hawaii, but it is presumed to have been introduced from somewhere in Asia or the Pacific, because the other species in the genus are native to these areas.\u00a0 In Hawaii, R<\/em>. calvertae<\/em> is reported to feed on Macaranga tanarius<\/em> (Euphorbiaceae) and Pipturus<\/em> sp. (Urticaceae) (Henry, 2017; J. Matsunaga, pers. comm.), but no information is available on the extent of damage inflicted on these plants by this bug.\u00a0 Very little information was found on the biology of this genus.\u00a0 Most collections of Rubrocuneocoris<\/em> appear to have been made with light or malaise traps, which provides little biological information.<\/p>\n

Worldwide Distribution<\/u><\/strong>:<\/u><\/strong>\u00a0 Rubrocuneocoris calvertae<\/em> is only known from Hawaii (Hawaii and Oahu islands), and it was presumably introduced there from an unknown location in east Asia or the Pacific (Henry, 2017; J. Matsunaga, pers. comm.).<\/p>\n

Official Control:<\/u><\/strong> Rubrocuneocoris calvertae <\/em>is not known to be under official control anywhere.<\/p>\n

California Distribution: <\/u><\/strong>\u00a0Rubrocuneocoris calvertae<\/em> is not known to be present in California (Symbiota Collections of Arthropods Network).<\/p>\n

California Interceptions:<\/u><\/strong>\u00a0 Rubrocuneocoris calvertae <\/em>has not been intercepted in California.<\/p>\n

The risk Rubrocuneocoris calvertae <\/em>wo<\/em>uld pose to California is evaluated below.<\/p>\n

Consequences of Introduction:<\/h5>\n

1) Climate\/Host Interaction:<\/strong> Rubrocuneocoris calvertae<\/em> has been reported to feed on plants in the families Euphorbiaceae and Urticaceae. There are plants in these families present throughout California.\u00a0 This insect is only known to be present in Hawaii, although it is presumed to be native to somewhere in east Asia or the Pacific.\u00a0 At least one species in the genus Rubrocuneocoris <\/em>occurs in the Primorye region of the Russian Federation, which suggests it may be tolerant of a more temperate climate (Vinokurov et al., 1988). \u00a0Therefore, even though it is likely that calvertae<\/em> originated in a tropical or subtropical area and is limited to such climates, it is also possible that this species is native to an area with a temperate climate, and thus could survive in much of California.\u00a0 Therefore, R. calvertae <\/em>receives a High (3)<\/strong> <\/span>in this category.<\/p>\n

\u2013 Low (1) Not likely to establish in California; or likely to establish in very limited areas.<\/p>\n

\u2013 Medium (2) may be able to establish in a larger but limited part of California.<\/p>\n

\u2013 High (3) <\/strong>likely to establish a widespread distribution in California.<\/span><\/p>\n

2) Known Pest Host Range: <\/strong>This species has been reported to feed on two families of plants, the Euphorbiaceae and Urticaceae. Its native distribution is unknown, but this species may feed on other plants there. \u00a0The unknown feeding habits in the (also unknown) native range are considered here.\u00a0 Therefore, calvertae<\/em> receives a Medium (2)<\/span><\/strong> in this category.<\/p>\n

\u2013 Low (1) has a very limited host range.<\/p>\n

\u2013 Medium (2) <\/strong>has a moderate host range.<\/span><\/p>\n

\u2013 High (3) has a wide host range.<\/p>\n

3) Pest Dispersal Potential:<\/strong> Rubrocuneocoris calvertae<\/em> presumably flies, because other species in the genus are caught at light traps (Schuh, 1984).\u00a0 Therefore, it receives a Medium (2)<\/span><\/strong> in this category.<\/p>\n

\u2013 Low (1) does not have high reproductive or dispersal potential.<\/p>\n

\u2013 Medium (2) <\/strong>has either high reproductive or dispersal potential.<\/span><\/p>\n

\u2013 High (3) has both high reproduction and dispersal potential.<\/p>\n

4) Economic Impact:<\/strong> This species feeds on plants.\u00a0 It is not known to be present in California, and it is possible that it has a very limited distribution and may not have been exposed to some economically-significant plants that are present in California.\u00a0 Therefore, even though there is no evidence that calvertae<\/em> is a pest elsewhere, there is still the possibility that it could become a pest in California if it became established here.\u00a0 If it became a pest in California, it could lower crop yield and increase crop production costs, for example, through increased pesticide use. \u00a0Therefore, it receives a Medium (2)<\/span> <\/strong>in this category.<\/p>\n

Economic Impact: A, B<\/span><\/strong><\/p>\n

A. <\/strong>The pest could lower crop yield.<\/span><\/p>\n

B. <\/strong>The pest could lower crop value (includes increasing crop production costs).<\/span><\/p>\n

The pest could trigger the loss of markets (includes quarantines).<\/p>\n

The pest could negatively change normal cultural practices.<\/p>\n

The pest can vector, or is vectored, by another pestiferous organism.<\/p>\n

The organism is injurious or poisonous to agriculturally important animals.<\/p>\n

The organism can interfere with the delivery or supply of water for agricultural uses.<\/p>\n

Economic Impact Score: 2<\/span><\/strong><\/p>\n

\u2013 Low (1) causes 0 or 1 of these impacts.<\/p>\n

\u2013 Medium (2) <\/strong>causes 2 of these impacts.<\/span><\/p>\n

\u2013 High (3) causes 3 or more of these impacts.<\/p>\n

5) Environmental Impact:<\/strong> As explained above, under Economic Impacts, there is the possibility that calvertae<\/em> could become a pest if it was established in California. This could trigger treatment programs, for example, in agriculture or ornamental plantings.\u00a0 There is a rare Euphorbia species in California, E. hooveri<\/em>, which could be attacked by R. calvertae<\/em> if it became established in California.\u00a0 Therefore, R. calvertae<\/em> receives a High (3)<\/span><\/strong> in this category.<\/p>\n

Evaluate the environmental impact of the pest on California using the criteria below.<\/p>\n

Environmental Impact: B, D<\/span><\/strong><\/p>\n

A. The pest could have a significant environmental impact such as lowering biodiversity, disrupting natural communities, or changing ecosystem processes.<\/p>\n

B. <\/strong>The pest could directly affect threatened or endangered species.<\/span><\/p>\n

C. The pest could impact threatened or endangered species by disrupting critical habitats.<\/p>\n

D. <\/strong>The pest could trigger additional official or private treatment programs.<\/span><\/p>\n

E. The pest significantly impacts cultural practices, home\/urban gardening or ornamental plantings.<\/p>\n

Environmental Impact Score: 3<\/span><\/strong><\/p>\n

\u2013 Low (1) causes none of the above to occur.<\/p>\n

\u2013 Medium (2) causes one of the above to occur.<\/p>\n

\u2013 High (3) <\/strong>causes two or more of the above to occur.<\/span><\/p>\n

Consequences of Introduction to California for Rubrocuneocoris calvertae<\/em>: Medium (12)<\/span><\/h5>\n

Add up the total score and include it here.<\/p>\n

\u2013Low = 5-8 points<\/p>\n

\u2013Medium <\/strong>= 9-12 points<\/span><\/p>\n

\u2013High = 13-15 points<\/p>\n

6) Post Entry Distribution and Survey Information:<\/strong> Rubrocuneocoris calvertae <\/em>is not known to be present in California. \u00a0It receives a Not established (0)<\/span><\/strong> in this category.<\/p>\n

\u2013Not established (0)<\/strong> Pest never detected in California, or known only from incursions.<\/span><\/p>\n

\u2013Low (-1) Pest has a localized distribution in California, or is established in one suitable climate\/host area (region).<\/p>\n

\u2013Medium (-2) Pest is widespread in California but not fully established in the endangered area, or pest established in two contiguous suitable climate\/host areas.<\/p>\n

\u2013High (-3) Pest has fully established in the endangered area, or pest is reported in more than two contiguous or non-contiguous suitable climate\/host areas.<\/p>\n

Final Score:<\/h5>\n

7) The final score is<\/strong> the consequences of introduction score minus the post entry distribution and survey information score: Medium (12)<\/span><\/strong><\/p>\n

Uncertainty:<\/h5>\n

The full extent (including native range) of the distribution of R. calvertae<\/em> are presumably not known.\u00a0 This means that the climatic tolerances and feeding habits of this insect are also unknown, which makes it challenging to determine its potential for impact in California.\u00a0 No information was found suggesting that any species in the genus Rubrocuneocoris<\/em> is a pest.\u00a0 This suggests that the genus may have a low potential for economic or environmental impact.<\/p>\n

Conclusion and Rating Justification:<\/h5>\n

Rubrocuneocoris calvertae<\/em> is only known from Hawaii, but it is presumed to be native somewhere in Asia or the Pacific.\u00a0 It is possible that it could have economic and environmental impacts if it became established in California.\u00a0 For these reasons, an \u201cA<\/strong>\u201d rating is justified.<\/p>\n
