Mini Risk Assessment Passionvine mealybug: Planococcus minor (Maskell) [Pseudococcidae: Hemiptera] Robert C. Venette & Erica E. Davis Department of Entomology, University of Minnesota St. Paul, MN 55108 March 2, 2004 Introduction Planococcus minor is a significant pest of more than 250 host plants in the Afrotropical, Australasian, Nearctic, Neotropical, and Oriental regions (Williams 1985, Ben-Dov 1994, USDA 2000, CAB 2003). Banana, citrus, cocoa, coffee, corn, grape, mango, potato and soybean are among the more notable agricultural crops that may be affected by this pest. The likelihood and consequences of establishment by P. minor in the US have been evaluated previously in commodity-based pest risk assessments. Previous analyses have concluded that the likelihood of this pest becoming established in the US is high and the consequences of its establishment would be severe. This new document is intended to provide useful information about whether P. minor should be the focus of a pest survey, and if so, to identify and evaluate available survey techniques. A B Figure 1.

Ecological Suitability. Rating: Medium. Planococcus minor is considered widespread through much of its geographic range, primarily in the tropics and subtropics (Williams 1985, Williams and Watson 1988, Cox 1989, Williams and Granara de Willink 1992, Ben-Dov 1994, USDA 2000). Planococcus minor is thought to be one of six species with origins in the Old World, and likely introduced to the Neotropics by trade (Cox 1989) The currently reported global distribution of P. minor suggests that the pest may be most closely associated with biomes characterized as desert and xeric shrubland; temperate grassland, CAPS PRA: Planococcus minor savannahs, and shrubland; and tropical and subtropical moist broad leaf forest. Consequently, we estimate that approximately 52% of the continental US would have a suitable climate for P. minor (Fig. 2). See Appendix A for a more complete description of this analysis. Figure 2. Predicted distribution of Planococcus minor in the continental US. 2. Host Specificity/Availability. Rating: High/High. This pest is highly polyphagous and feeds on a variety of wild and cultivated plants. There are more than 250 reported host plants in nearly 80 families, including: Acanthaceae: ilang-ilang (Cananga odorata) Aphelandra sp. soursop (Annona muricata) Graptophyllum sp. sugar apple (Annona squamosa) Justica carnea Apiaceae: Odontonema sp. wild celery (Apium graveolens) Pachystachys cocineae Apocynaceae: Agavaceae: templetree (Plumeria rubra) Mauritius hemp (Furcraea foetida Araceae: [=gigantea]) Aglaonema sp.
