Coleoptera: Cerambycidae<\/h5>\n\n\n\n
Pest Rating: A<\/h5>\n\n\n\n
\n\n\n\n

PEST RATING PROFILE<\/h3>\n\n\n\n

Initiating Event:<\/h5>\n\n\n\n

Acalolepta aesthetica <\/em>is currently Q-rated.  It was introduced to, and is now established on the island of Hawaii.  A permanent pest rating proposal is required to support an official pest rating.<\/p>\n\n\n\n

History & Status:<\/h5>\n\n\n\n

Background:<\/u><\/strong>  Acalolepta aesthetica<\/em> is a large (approximately 3 cm in length) longhorned beetle.  The species has long antennae, which is typical of the family, and the dorsal (upper) surface is brown in color and velvety (Olliff, 1890).  As is the case with many cerambycids, the larvae feed inside tree trunks.  On the island of Hawaii, this beetle has been reported attacking Artocarpus altilis<\/em> (Moraceae), Aleurites moluccanus<\/em> (Euphorbiaceae), Citrus x latifolia<\/em> (Rutaceae), Cycas<\/em> sp. (Cycadaceae), Theobroma cacao<\/em> (Malvaceae), and Trema orientalis<\/em> (Cannabaceae).  Reports indicate that healthy trees are attacked (J. Matsunaga, pers. comm.).<\/p>\n\n\n\n

Worldwide Distribution<\/u><\/strong>:<\/u><\/strong>  Acalolepta aesthetica<\/em> is native to Australia and was introduced to Hawaii at least as early as 2009, when the first specimens were collected there (J. Matsunaga, pers. comm.).<\/p>\n\n\n\n

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

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

California Interceptions:<\/u><\/strong>  Acalolepta aesthetica <\/em>has not been intercepted in California.<\/p>\n\n\n\n

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

Consequences of Introduction:<\/h5>\n\n\n\n

1) Climate\/Host Interaction:<\/strong> Although Acalolepta aesthetica<\/em> feeds on a variety of trees, and suitable hosts may be present over much of California, this beetle appears to be limited to areas with a tropical or subtropical climate (Atlas of Living Australia). There is little evidence this species could become established in more than a small portion of California.  Therefore, Acalolepta aesthetica <\/em>receives a Low (1)<\/strong> <\/span>in this category.<\/p>\n\n\n\n

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

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

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

2) Known Pest Host Range: <\/strong>Acalolepta aesthetica<\/em> was reported to attack trees in six families in Hawaii. Therefore, it receives a High (3)<\/span><\/strong> in this category.<\/p>\n\n\n\n

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

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

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

3) Pest Dispersal Potential:<\/strong> Acalolepta aesthetica<\/em> presumably flies, and due to its size, it could probably cover long distances.  Because the larvae live inside wood, this species could be dispersed artificially via movement of infested wood.  Therefore, it receives a Medium (2)<\/span> <\/strong>in this category.<\/p>\n\n\n\n

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

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

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

4) Economic Impact:<\/strong> The genus Acalolepta<\/em> includes several species that are known pests (Slipinski and Ascalona, 2013).  Acalolepta aesthetica<\/em> is reported to damage trees, including crop trees, in Hawaii.  Citrus is one of the trees reported to be attacked.  If it became established in California, Acalolepta aesthetica<\/em> could become a pest of crop trees, including citrus.  This could result in lower yield and increased production costs for citrus, and there could also be a loss of markets.  Therefore, it receives a High (3)<\/strong><\/span> in this category.<\/p>\n\n\n\n

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

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

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

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

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

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

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

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

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

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

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

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

5) Environmental Impact:<\/strong> Acalolepta aesthetica<\/em> is reported to attack and damage a variety of trees in six families. If this beetle became established in California, it could attack native California trees.  In addition, ornamental trees, including citrus, and cycads, could be attacked.  Therefore, it receives a High (3)<\/strong><\/span> in this category.<\/p>\n\n\n\n

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

Environmental Impact: A, E<\/span><\/strong><\/p>\n\n\n\n

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

7) Post Entry Distribution and Survey Information:<\/strong> Acalolepta aesthetica<\/em> is not known to occur in California.  It receives a Not established (0)<\/span><\/strong> in this category.<\/p>\n\n\n\n

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

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

Final Score:<\/h5>\n\n\n\n

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

Uncertainty:<\/h5>\n\n\n\n

There is very little information available on the biology of this species.  The most significant uncertainty regarding this species is climatic tolerance, but there could also be host range extension once it encountered the diverse flora of California.  There is a possibility that it may require a tropical or subtropical climate, in which case it may not be capable of becoming established in California.<\/p>\n\n\n\n

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

Acalolepta aesthetica<\/em> attacks a wide range of trees, including citrus.  The species is not known to be present in California, but if it was established here, it could become a pest of trees in agriculture and ornamental settings, and potentially in the environment.  For these reasons, an \u201cA<\/strong>\u201d rating is justified.<\/p>\n\n\n\n
