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

Planococcus minor<\/em> is frequently intercepted by CDFA and is presently assigned 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<\/u>:<\/strong>\u00a0 Planococcus minor<\/em> is a highly polyphagous mealybug that feeds on a wide variety of valuable agricultural crops and ornamental plants.\u00a0 Infestations may cause reduced yield, lower plant or fruit quality, stunted growth, discoloration, and leaf loss1<\/sup>.\u00a0 The mealybugs also excrete large volumes of honeydew that reduces photosynthetic activity and attracts ants as it builds up on leaves and fruit1<\/sup>.\u00a0 The mealybug can be an economic pest at low population densities by vectoring viruses that kill plants1<\/sup>.\u00a0 However, it has not emerged as a serious economic pest in much of its range presumably due to the presence of predators and parasitoids1<\/sup>.\u00a0 Known hosts include:\u00a0 Acanthaceae<\/strong>: Aphelandra <\/em>sp.2<\/sup>, Graptophyllum sp.<\/em>2<\/sup>, Justica carnea<\/em>2<\/sup>, Odontonema <\/em>sp.2<\/sup>, Pachystachys coecinea<\/em>2<\/sup>;

Worldwide Distribution<\/u>:<\/strong> Planococcus minor<\/em> is probably Asian in origin1<\/sup>.\u00a0 From there it has invaded much of the Neotropical region spanning from Mexico south to Argentina1,2<\/sup>.\u00a0 It was first found in Hawaii in 2009 and Florida in 2010.<\/p>\n

Official Control<\/u>:<\/strong> Planococcus minor<\/em> is listed as a harmful organism by China, the Republic of Korea, and Japan3<\/sup>.<\/p>\n

California Distribution<\/u>:\u00a0<\/strong> Planococcus minor<\/em> has never been found in the environment of California.<\/p>\n

California Interceptions<\/u>:\u00a0<\/strong> Planococcus minor<\/em> has been intercepted 89 times by CDFA\u2019s high risk programs, border stations and dog teams.\u00a0 Interceptions have occurred on plants and fresh plant parts mostly from Hawaii, but also from Florida, Washington, and Pennsylvania.<\/p>\n

The risk Planococcus minor<\/em> (pacific mealybug) would pose to California is evaluated below.<\/p>\n

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

1) Climate\/Host Interaction<\/span>:<\/strong> Host plants of Planococcus minor<\/em> are widely grown throughout California as agricultural crops and ornamentals. The mealybug is likely to establish wherever suitable host material is found and 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.<\/p>\n

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

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

2) Known Pest Host Range<\/span>:<\/strong> Planococcus minor<\/em> feeds on more than 250 plants belonging to 66 families and receives a High (3)<\/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.<\/p>\n

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

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

3) Pest Dispersal Potential<\/span>:<\/strong> Pacific mealybug can complete a generation in less than a month and each female lays between 206 and 270 eggs, indicating a high reproductive rate.\u00a0 Mealybugs can be transported long distances when infested plants or fresh plant parts are moved.\u00a0 They may also disperse locally by crawling, wind, or by hitchhiking on clothing, equipment, or animals.\u00a0 Planococcus minor<\/em> receives a High (3)<\/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.<\/p>\n

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

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

4) Economic Impact<\/span>:<\/strong> Planococcus minor<\/em> may lower the value of nursery stock by disfiguring plants with its presence and sooty mold.\u00a0 It may also increase production costs for a wide variety of crops.\u00a0 Several of California\u2019s trading partners list pacific mealybug as a harmful organism, so exports of fresh fruit including citrus and grapes may be disrupted.\u00a0 Pacific mealybug has been implicated in the transmission of virus diseases between plants1<\/sup>.\u00a0 Furthermore, honeydew secreted by the mealybugs will attract ants, which may injure parasitic wasps, disrupting biological control programs for other pests.\u00a0 Planococcus minor<\/em> receives a High (3)<\/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.<\/p>\n

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

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

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

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

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

G. 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.<\/p>\n

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

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

5) Environmental Impact<\/span>:<\/strong> Planococcus minor<\/em> is not expected to lower biodiversity, disrupt natural communities, or change ecosystem processes.\u00a0 It may feed on threatened and endangered species such as Wiggins\u2019 croton (Croton wigginsii<\/em>) and small-leaved rose (Rosa minutifolia<\/em>).\u00a0 The mealybugs are not likely to disrupt critical habitats.\u00a0 They may trigger new treatment programs in agriculture and by residents who find infested plants unsightly.\u00a0 Pacific mealybug feeds on a wide variety of popular ornamental plants and plants common in home\/urban gardens.\u00a0 Planococcus minor<\/em> receives a High (3)<\/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.<\/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<\/strong>. The pest significantly impacts cultural practices, home\/urban gardening or ornamental plantings.<\/span><\/p>\n

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

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

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

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

Consequences of Introduction to California for Planococcus minor<\/em> (Pacific Mealybug): High (15)<\/span><\/strong><\/h5>\n

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

–Low<\/strong> = 5-8 points<\/p>\n

–Medium<\/strong> = 9-12 points<\/p>\n

–High<\/strong> = 13-15 points<\/span><\/p>\n

6) Post Entry Distribution and Survey Information<\/span>:<\/strong> Planococcus minor<\/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><\/p>\n

–Low (-1)<\/strong> Pest has a localized distribution in California, or is established in one suitable climate\/host area (region).<\/p>\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.<\/p>\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<\/strong> the consequences of introduction score minus the post entry distribution and survey information score: High (15)<\/strong><\/span><\/p>\n

Uncertainty: \u00a0<\/strong><\/h5>\n

Recent formal mealybug surveys in California have focused on Proteas and would have been unlikely to detect pacific mealybug.\u00a0 It is possible that the mealybug could be present in some localities.<\/p>\n

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

Planococcus minor<\/em> has never been found in California and is likely to have significant economic and environmental impacts if it were to establish in the state.\u00a0 An \u201cA\u201d rating is justified.<\/p>\n
