PEST RATING PROFILE<\/strong><\/h5>\n
Initiating Event: <\/strong><\/h5>\n

Pinnaspis uniloba<\/em> is occasionally intercepted by CDFA and presently has a temporary rating of \u201cQ\u201d.\u00a0 A pest rating proposal is required to assign a permanent pest rating.<\/p>\n

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

Background<\/strong><\/span>:\u00a0 Pinnaspis uniloba<\/em> is an armored scale insect that feeds on a variety of plants.\u00a0 Known hosts include: Apocynaceae<\/strong>: Alyxia sp<\/em>1,2<\/sup>, maile (Alyxia olivaeformis<\/em>1,2<\/sup>); Fabaceae<\/strong>: Bauhinia racemosa<\/em>1,2<\/sup>; Magnoliaceae<\/strong>: Michelia sp.<\/em>1,2<\/sup>; Oleaceae<\/strong>: Osmanthus sp.<\/em>1,2<\/sup>, sweet olive (Osmanthus fragrans<\/em>1,2<\/sup>), fortune\u2019s tea olive (Osmanthus fortunei<\/em>1,2<\/sup>); Rutaceae<\/strong>: bael fruit (Aegle marmelos<\/em>1,2<\/sup>); Theaceae<\/strong>: Adinandra sp.<\/em>1,2<\/sup>, Adinandra milletti<\/em>1,2<\/sup>, Adinandra ryukyuensis<\/em>2<\/sup>, Japanese camellia (Camellia japonica<\/em>1,2<\/sup>), Cleyera japonica<\/em>1,2<\/sup>, Cleyera ochnacea<\/em>1,2<\/sup>, Eurya japonica<\/em>1,2<\/sup>, Thea japonica<\/em>1,2<\/sup>.\u00a0 Pinnaspis uniloba<\/em> may be transported long distances when infested plants or fresh plant parts are moved.<\/p>\n

Worldwide Distribution<\/strong><\/span>: Pinnaspis uniloba<\/em> is probably native to Asia.\u00a0 It has been reported in China1,2<\/sup>, India1,2<\/sup>, Japan1,2<\/sup>, and South Korea2<\/sup>.\u00a0 From there it has spread to the Hawaiian Islands.<\/p>\n

Official Control<\/strong><\/span>: Pinnaspis uniloba<\/em> is not known to be under official control in any other states or nations3<\/sup>.<\/p>\n

California Distribution<\/strong><\/span>:\u00a0 Pinnaspis uniloba<\/em> has never been found in the environment of California.<\/p>\n

California Interceptions<\/span><\/strong>:\u00a0 Pinnaspis uniloba<\/em> has been intercepted 92 times on plants and fresh plant material from Hawaii.\u00a0 Many of these interceptions have occurred on Maile (Alyxia <\/em>sp.) leaf leis.<\/p>\n

The risk Pinnaspis uniloba<\/em> (unilobed scale) would pose to California is evaluated below.<\/p>\n

Consequences of Introduction:\u00a0<\/strong><\/h5>\n

Climate\/Host Interaction<\/strong>: A few of the host plants of Pinnaspis uniloba<\/em> are widely grown as ornamentals in California and the scale may be expected to establish everywhere they are grown. It receives a High (3)<\/strong><\/span> in this category.<\/p>\n

Evaluate if the pest would have suitable hosts and climate to establish in California.\u00a0 Score:<\/p>\n

– Low (1)<\/strong> Not likely to establish in California; or likely to establish in very limited areas.
\n– Medium (2)<\/strong> may be able to establish in a larger but limited part of California.
\n– High (3)<\/strong> likely to establish a widespread distribution in California.<\/span><\/p>\n

2) \u00a0Known Pest Host Range<\/strong>: Pinnaspis uniloba<\/em> is known to feed on 16 species of plants in six families.\u00a0 It receives a Medium (2)<\/strong><\/span> in this category.<\/p>\n

Evaluate the host range of the pest. Score:<\/p>\n

– Low (1)<\/strong> has a very limited host range.
\n– Medium (2)<\/strong> has a moderate host range.<\/span>
\n– High (3)<\/strong> has a wide host range.<\/p>\n

3) \u00a0Pest Dispersal Potential<\/strong>: Pinnaspis uniloba<\/em> has only one generation per year.\u00a0 Armored scales may be transported long distances when infested plants are moved and may be dispersed locally by crawling, wind, or by hitchhiking on clothing, equipment, or animals.\u00a0 Pinnaspis uniloba<\/em> receives a Medium (2) <\/strong><\/span>in this category.<\/p>\n

Evaluate the natural and artificial dispersal potential of the pest. Score:<\/p>\n

– Low (1)<\/strong> does not have high reproductive or dispersal potential.
\n– Medium (2)<\/strong> has either high reproductive or dispersal potential.<\/span>
\n– High (3)<\/strong> has both high reproduction and dispersal potential.<\/p>\n

4) \u00a0Economic Impact<\/strong>: Pinnaspis uniloba<\/em> is not expected to lower any crop yields.\u00a0 It may reduce the value of some nursery stock by disfiguring plants with its presence.\u00a0 It is not expected to disrupt markets, change cultural practices, vector other organisms, injure animals, or interfere with water supplies.\u00a0 Pinnaspis uniloba<\/em> receives a Low (1)<\/strong><\/span> in this category.<\/p>\n

Evaluate the economic impact of the pest to California using the criteria below. Score:<\/p>\n

A. The pest could lower crop yield.
\nB. <\/strong>The pest could lower crop value (includes increasing crop production costs).<\/span>
\nC. The pest could trigger the loss of markets (includes quarantines).
\nD. The pest could negatively change normal cultural practices.
\nE. The pest can vector, or is vectored, by another pestiferous organism.
\nF. The organism is injurious or poisonous to agriculturally important animals.
\nG. The organism can interfere with the delivery or supply of water for agricultural uses.<\/p>\n

– Low (1)<\/strong> causes 0 or 1 of these impacts.<\/span>
\n– Medium (2)<\/strong> causes 2 of these impacts.
\n– High (3)<\/strong> causes 3 or more of these impacts.<\/p>\n

5) \u00a0Environmental Impact<\/strong>: Pinnaspis uniloba<\/em> is not expected to lower biodiversity, disrupt natural communities, or change ecosystem processes.\u00a0 It is not expected to directly affect threatened or endangered species or disrupt critical habitats.\u00a0 It might trigger chemical treatments in the nursery industry and by residents who find infested ornamentals unsightly.\u00a0 It is not expected to significantly impact cultural practices, home\/urban gardening, or ornamental plantings.\u00a0 Pinnaspis uniloba<\/em> receives a Medium (2)<\/strong> <\/span>in this category.<\/p>\n

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

A. The pest could have a significant environmental impact such as lowering biodiversity, disrupting natural communities, or changing ecosystem processes.
\nB. The pest could directly affect threatened or endangered species.
\nC. The pest could impact threatened or endangered species by disrupting critical habitats.
\nD.<\/strong> The pest could trigger additional official or private treatment programs.<\/span>
\nE. The pest significantly impacts cultural practices, home\/urban gardening or ornamental plantings.<\/p>\n

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

– Low (1)<\/strong> causes none of the above to occur.
\n– Medium (2)<\/strong> causes one of the above to occur.<\/span>
\n– High (3)<\/strong> causes two or more of the above to occur.<\/p>\n

Consequences of Introduction to California for Pinnaspis uniloba<\/em> (Unilobed Scale):<\/strong>\u00a0 Medium (10)<\/strong><\/span><\/h5>\n

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

– Low<\/strong> = 5-8 points
\n– Medium<\/strong> = 9-12 points<\/span>
\n– High<\/strong> = 13-15 points<\/p>\n

6) \u00a0Post Entry Distribution and Survey Information<\/strong>: Pinnaspis uniloba<\/em> has never been found in California and receives a Not established (0) <\/strong><\/span>in this category.<\/p>\n

Evaluate the known distribution in California. Only official records identified by a taxonomic expert and supported by voucher specimens deposited in natural history collections should be considered. Pest incursions that have been eradicated, are under eradication, or have been delimited with no further detections should not be included.<\/p>\n

– Not established (0)<\/strong> Pest never detected in California, or known only from incursions.<\/span>
\n– Low (-1)<\/strong> Pest has a localized distribution in California, or is established in one suitable climate\/host area (region).
\n– Medium (-2)<\/strong> Pest is widespread in California but not fully established in the endangered area, or pest established in two contiguous suitable climate\/host areas.
\n– High (-3)<\/strong> 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 the consequences of introduction score minus the post entry distribution and survey information score: Medium (10)<\/strong><\/span><\/p>\n

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

Pinnaspis uniloba<\/em> is currently not known to be present anywhere in North or South America.\u00a0 It is possible that some states or nations could impose new trade restrictions if it were to become abundant in California.<\/p>\n

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

Pinnaspis uniloba<\/em> has never been found in California.\u00a0 It is expected to have limited impacts if it were to enter the state.\u00a0 The scale is most often intercepted on leis and, because of its limited host range, is unlikely to encounter suitable host material when it enters the state via this pathway.\u00a0 A \u201cB\u201d rating is justified.<\/p>\n
