2.  35 species  Caribbean and Central America  A. cocois  A. pulvinatus (CR- Bahamas)  FLORIDA: dispersus, dugesii, rugioperculatus  highly polyphagous, pestiferous  parasitoids present, variable efficacy (0-100%) Aleurodicus Ian Stocks, Division of Plant Industry A. rugioperculatus Pest Alert

3. Aleurodicus rugioperculatus: Aleyrodidae Rugose spiraling whitefly (AKA gumbo-limbo spiraling whitefly) Ian Stocks, Division of Plant Industry  submitted samples often just with egg spirals  ♀ ’s may oviposit on a wider host range than is suitable for development  examine a wider area to see if nymphs or pupae are present  in palms, esp. common along midrib  control and biology research by Dr. C. Mannion, UF-TREC  massive quantities of honeydew, sooty mold and sticky wax  pools, cars, decks and patios

5. Vryburgia trionymoides: Pseudococcidae  described from Kenya in 1961  not recorded again until found in California, now locally established, common in grow houses  Florida: 2005, 2009- big box retailers in S. Florida  major infestations found in Spring, 2011  Nassau Co., Duval Co. (big box retailers )  risk assessment: unknown, but can kill a succulent if left untreated  very similar to citrus mealybug, co-occur (slight difference in body color, wax pattern)  look CLOSELY in rosettes and near stem Photo: Andrew Derksen, DPI Ian Stocks, Division of Plant Industry Photo: Lyle Buss, UF

7. Phenacoccus multicerarii: Pseudococcidae  described in 2007 from specimens collected in 1949 from Caracas, Venezuala found in a museum collection, unknown host  not seen again until June, 2011, from multiple hosts at a retail nursery in Fernandina Beach (Nassau Co.)  trace-back initiated, nursery in Orange County identified and subsequently verified  recently collected specimens from Port Everglades AloaceaeAloe vera AsteraceaePseudognaphalium obtusifolium BegoniaceaeBegonia sp.

8. Photo: Ian Stocks, DPI Phenacoccus multicerarii  3.5 to 4 mm long  pale yellow- grey  light dusting of powdery wax  lateral filaments (wax protrusions along flank)  ovisac (cottony mass with eggs/ crawlers)  very similar to P. madeirensis, the madeira mealybug and P. solani complex (solani, solenopsis)  worldwide, many Phenacoccus are very destructive  not shy- very visible on plant Ian Stocks, Division of Plant Industry Photo: Ian Stocks, DPIPhoto: Lisa Hassell, DPI

9. Planococcus minor: Pseudococcidae. Passionvine mealybug  Old-world species, now found almost world-wide  present in Caribbean, S. America and C. America since 1980’s  severe pest of many plant species: USDA watch-list  “Positively” identified in Florida in 2010  found again in June 2011 at a nursery in Palm Beach County  impossible to distinguish between P. citri and P. minor in the field  will it be a pest? how widely distributed?  will P. citri parasitoids/predators find it to be a suitable host?  http://www.freshfromflorida.com/pi/pest_alerts/pdf/planococcus- minor.pdf Ian Stocks, Division of Plant Industry
