Pest Rating: A<\/h5>\n

PEST RATING PROFILE<\/h3>\n

Initiating Event:<\/h5>\n

Hylesinus cingulatus <\/em>is currently Q-rated.\u00a0 A permanent pest rating proposal is required to support an official pest rating.<\/p>\n

History & Status:<\/h5>\n

Background:<\/u><\/strong>\u00a0 <\/em>Like most bark beetles, Hylesinus <\/em>species develop in the phloem (inner bark).\u00a0 \u00a0Hylesinus cingulatus<\/em> has been reported to feed on Fraxinus mandshurica<\/em> and F. longicuspis<\/em>.\u00a0 According to one source, it breeds in windthrown trees and does not cause significant damage in forests (Kurenzov, 1941).\u00a0 In at least some (possibly most) species of Hylesinus,<\/em> adults feed on healthy trees prior to reproduction; this is referred to as maturation feeding.\u00a0 Other species of Hylesinus<\/em> are known to attack live, but stressed (through drought, for instance) trees.<\/p>\n

Worldwide Distribution<\/u><\/strong>:<\/u><\/strong> Found in China, Korea, Japan, and the Primorye region of the Russian Far East.<\/p>\n

Official Control:<\/u><\/strong> This species does not appear to be under official control anywhere.<\/p>\n

California Distribution: <\/u><\/strong>\u00a0This species is not known to be present in California.<\/p>\n

California Interceptions:<\/u><\/strong> Hylesinus cingulatus<\/em> has apparently never been intercepted in California.<\/p>\n

The risk Hylesinus cingulatus <\/em>would pose to California is evaluated below.<\/p>\n

Consequences of Introduction:<\/h5>\n

1) Climate\/Host Interaction:<\/strong> The climate represented by the native distribution of Hylesinus cingulatus<\/em> suggests that it could become established in some parts of California.\u00a0 Ash trees (Fraxinus<\/em>) are widely distributed in California. Therefore, it receives a Medium (2)<\/span><\/strong> 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)<\/strong> may be able to establish in a larger but limited part of California.<\/span><\/p>\n

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

2) Known Pest Host Range: <\/strong>This species apparently is only known to feed on two species of Fraxinus<\/em>. Assuming it is likely restricted to this genus of host tree, it receives a Low (1)<\/span><\/strong> in this category.<\/p>\n

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

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

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

3) Pest Dispersal Potential:<\/strong> Hylesinus cingulatus<\/em> is capable of sustained flight. The species could be moved in firewood or wood products, although the apparently limited host range might reduce the chances of such movement.\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> Hylesinus cingulatus<\/em> has a fairly limited host range, at least in its native range.\u00a0 The species apparently feeds on trees that are already damaged or in decline, although limited information on the biology of this species was obtained.\u00a0 Therefore, it receives a Low (1)<\/span> <\/strong>in this category.<\/p>\n

Economic Impact:<\/p>\n

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

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

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

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

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

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

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

Economic Impact Score: 1<\/span><\/strong><\/p>\n

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

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

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

5) Environmental Impact:<\/strong> Hylesinus cingulatus <\/em>does not appear to have much potential for environmental impact. The species apparently feeds on dead or stressed trees, although limited information on the biology of this species was obtained.\u00a0 One California species of Fraxinus<\/em> is rare ( parryi<\/em>), but it occurs in a desert area that is unlikely to be invaded by H. cingulatus<\/em>.\u00a0 Therefore, H. cingulatus<\/em> receives a Low (1)<\/span> <\/strong>in this category.<\/p>\n

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

Environmental Impact:\u00a0<\/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. The pest could directly affect threatened or endangered species.<\/p>\n

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

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

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

Score the pest for Environmental Impact. Score:<\/p>\n

Environmental Impact Score: 1<\/span><\/strong><\/p>\n

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

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

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

Consequences of Introduction to California for Hylesinus cingulatus<\/em>: Low (7)<\/span><\/h5>\n

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

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

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

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

6) Post Entry Distribution and Survey Information:<\/strong> Hylesinus cingulatus <\/em>is not known to be present in California.\u00a0 It 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

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

Uncertainty:<\/h5>\n

There may be information on the biology of this species that was not accessible to this author because it is not in English, although an attempt was made to translate the available literature.\u00a0 If this species was established in California, it could have a broader host range here than it does in Asia.\u00a0 If Hylesinus cingulatus<\/em> species behaved differently in California, for instance, by feeding on trees that were not already killed or damaged, there would be potential for environmental impact.\u00a0 In addition, newly-emerged adults of some species in the genus are known to feed (\u201cmaturation feeding\u201d) on healthy trees.\u00a0 If this is the case with H. cingulatus<\/em>, there is greater potential for economic and environmental impacts, especially when it is considered that fungi are associated with bark beetles and maturation feeding could possibly vector pathogenic fungi to healthy trees.<\/p>\n

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

Although H. cingulatus<\/em> does not behave as a serious pest in its native range, and it is perhaps likely that it would have no more serious an impact in California if it were introduced here, there are reasons to be cautious.\u00a0 Maturation feeding by adults could damage trees and could result in the transmission of pathogenic fungi.\u00a0 In addition, it is possible that this beetle could feed on new host trees in California.\u00a0 For these reasons, an \u201cA\u201d<\/strong> rating is justified.<\/p>\n
