For the month of May, there were 643 samples consisting of 3,503+ specimens. In June, there were 1,299 samples consisting of 13,314+ specimens. Some of the samples processed are listed below:
ORNAMENTALS, WOODY PLANTS AND PALMS: Ravenea rivularis (majesty palm)-- Dysmicoccus brevipes (Cockerell), pineapple mealybug: A moderate infestation involved all of 50,000 plants at a nursery in Lake Worth (Palm Beach County; E98-1094; Thomas L. Salisbury; 15 April 1998). Another moderate infestation involved 80% of 4,000 plants at a nursery in Boynton Beach (Palm Beach County; E98-1150; Ellen J. Tannehill; 30 April 1998).
-- Rhizoecus hibisci Kawai & Takagi, a root mealybug: Infestations involved 50,000 and 3,000 majesty palm plants, respectively, at nurseries in Lake Worth (Palm Beach County; E98-1103, E98-1097; Thomas L. Salisbury; 23 April 1998, 15 April 1998). This root mealybug has been a regulatory problem for shipment of plants to California (Dr. Avas B. Hamon).
Sabal palmetto (cabbage palm, a native species)-- Comstockiella sablais (Comstock), palmetto scale: A moderate infestation was found at a discount store in Davie (Broward County; E98-1633; William A. Thiel; 22 February 1998). This is a common scale on palmetto and is usually not a problem in the wild, but it possibly is a problem in cultivation where chemical sprays are used (Dr. Avas B. Hamon).
Syagrus romanzoffiana (queen palm)-- Nipaecoccus nipae (Maskell), coconut mealybug: A severe infestation involved all of 800 plants at a nursery in Ft. Lauderdale (Broward County; E98-1139; Maria S. Quintanilla; 29 April 1998).
ORNAMENTALS, FOLIAGE PLANTS: bamboo-- Antonina pretiosa Ferris, noxious bamboo mealybug: An infestation was found at a nursery in Coral Gables (Dade County; E98-1891; Gwen H. Myres; 12 June 1998).
Breynia nivosa (snowbush)-- Melanochroia chephise (Cramer), a geometrid moth: A severe infestation with larvae defoliating a hedge was found at a residence in Pompano Beach (Broward County; E98-1538; James 'Keith' Harris; 21 May 1998). This is the first time this species has been recorded as a plant pest (Dr. John B. Heppner).
Ilex x attenuata 'Savannah' (Savannah holly)-- Asterolecanium puteanum Russell, holly pit scale: A severe infestation was found on established plants in the landscape at a nursery in Jacksonville (Duval County; E98-1942; Flewellyn W. Podris; 17 June 1998). Gall-like swellings on branches were caused by scale insects feeding at those sites (Dr. Avas B. Hamon).
Cycas szechuanensis (Sichuan cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-698; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 26 February 1998). NEW DPI HOST RECORD.
Dendrocalamus latiflorus (mei-nung or ma bamboo)-- Chaetococcus bambusae (Maskell), giant bamboo mealybug: A moderate infestation was found on a plant at a botanical garden in Miami (Dade County; E98-1635; Don Evans, botanical garden employee; 28 May 1998). Chaetococcus bambusae (Maskell) is related to the legless mealybug genus Antonina. It is very conspicuous on bamboo since the adult female is dark brown, large, heavily sclerotized, and with a white fringe of wax. Although this is the first known infestation in the continental U.S., this mealybug possibly occurs where giant bamboo is grown (Dr. Avas B.Hamon). NEW RECORD FOR THE CONTINENTAL UNITED STATES.
Dioön califanoi (Califono's cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-696; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 26 February 1998). NEW DPI HOST RECORD.
Dioön merolae (Merola's cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-697; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 26 February 1998). NEW DPI HOST RECORD.
Dioön rzedowskii (Rzedowski's cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-694; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 26 February 1998). NEW DPI HOST RECORD.
Encephalartos, affine E. lebomboensis (a cycad, similar to Lebombo cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-706; Forrest W.

Encephalartos manikensis (Rhodesian cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-500; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 19 February 1998). NEW DPI HOST RECORD.
Microcycas calocoma (palma corcho, or hairy coned cycad)-- Aulacaspis yasumatsui Takagi, cycad aulacaspis scale: An infestation was found at a botanical garden in Miami (Dade County; E98-703; Forrest W. 'Bill' Howard, University of Florida's Ft. Lauderdale Research and Extension Center; 26 February 1998). NEW DPI HOST RECORD.
Murraya paniculata (orange-jessamine, or Chinese box)-- Diaphorina citri Kuwayama, Asian citrus psyllid: A slight infestation was found at a residence in Tamarac (Broward County; E98-1846; James 'Keith' Harris and Dennis C. Clinton; 4 June 1998). NEW DPI COUNTY RECORD.
-- Diaphorina citri Kuwayama, Asian citrus psyllid: A severe infestation was found at a discount store in Oakland Park (Broward County; E98-1911; James 'Keith' Harris; 12 June 1998).
ORNAMENTALS, FLOWERING PLANTS: Hibiscus rosa-sinensis (hibiscus, or China-rose)-- Aleurodicus dugesii Cockerell, giant whitefly: A severe infestation on several plants was found at a bank in Stuart (Martin County; E98-1901; Kenneth L. Hibbard and Dr. Susan E. Halbert; 8 June 1998). NEW DPI COUNTY RECORD.
-- Aleurodicus dugesii Cockerell, giant whitefly: Slight infestations were found at an apartment complex and a residence in Casselberry (Seminole County; E98-1900, 1902; Anne F. Weathers; 10 June 1998). There were parasites in nearly every specimen; biological control is working beautifully (Dr. Avas B. Hamon and Dr. Ru Nguyen).
Maranta leuconeura var. erythroneura (red-veined herringbone plant)-- Chaetanaphothrips orchidii (Moulton), orchid thrips: A moderate infestation was found on 500 of 1500 plants at a nursery in Apopka (Orange County; E98-1045; Leslie J. Wilber and Anthony N. Capitano; 21 April 1998).
FOREST AND SHADE TREES: Ulmus parvifolia (Chinese elm)-- Tinocallis ulmiparvifoliae Matsumura, an Asian elm aphid: A slight infestation was found on trees growing in the parking lot of the Tavares DPI office (Lake County; E98-1287; Dr. Susan E. Halbert and Christine M. Murphy; 6 May 1998). This aphid occurs throughout east Asia and is quite common in China. It was detected in England on bonsai U. parvifolia. Chinese elms are popular bonsai cultivars in the USA, as well. Since T. ulmiparvifoliae had to have been imported into Florida on a living elm tree, it is quite possible that it arrived here on bonsai plants from Asia. Tinocallis ulmiparvifoliae is not likely to become a serious pest in Florida, but high populations may produce enough honeydew to become a nuisance for parked cars, yard furniture, etc. (Dr. Susan E. Halbert). (Stroyan 1977). NEW RECORD FOR THE WESTERN HEMISPHERE.
CITRUS: Citrus aurantifolia (key lime)-- Diaphorina citri Kuwayama, Asian citrus psyllid: A slight infestation was found at a residence in Delray Beach (Palm Beach County; E98-1751; Dr. Susan E. Halbert, Ellen J. Tannehill, Dennis C. Clinton and Dr. Larry G. Brown; 2 June 1998). Asian citrus psyllid is one of the most important pests of citrus in most of Asia, several islands in the Indian Ocean, and Saudi Arabia. It causes damage to the crop primarily by transmitting phloem limited bacteria that cause citrus greening disease. Asian citrus psyllid also occurs in Brazil and Argentina, but it is regarded as a relatively minor pest because the pathogens are absent. The status of the greening pathogens in Florida is unknown at this time (Dr. Susan E. Halbert). NEW RECORD FOR NORTH AMERICA.
Citrus aurantium (sour orange)-- Diaphorina citri Kuwayama, Asian citrus psyllid: A slight infestation was found on a plant in a business landscape in Teguesta (Martin County; E98-1889; Kenneth L. Hibbard and Dr. Susan E. Halbert; 8 June 1998). A plant sample submitted for greening analysis was negative (Dr. Richard F. Lee, University of Florida's Citrus Research and Extension Center, Lake Alfred). NEW DPI COUNTY RECORD.
Citrus x paradisi (grapefruit)-- Anasa scorbutica (Fabricius), a coreid bug: A specimen was collected in a sweep-net sample on grapefruit leaves at a citrus nursery in Lithia (Hillsborough County; E98-1348; Alan R. Haynes and Stacy A. Tyrala; 13 May 1998). This insect breeds on Cucurbita. NEW DPI COUNTY RECORD.
-- Diaphorina citri Kuwayama, Asian citrus psyllid: A slight infestation was found at a residence in Delray Beach (Palm Beach County; E98-1753; Dr. Susan E. Halbert, Ellen J. Tannehill, Dennis C. Clinton, and Dr. Larry G. Brown; 2 June 1998). Adults, eggs and immature were all present on new shoots in the center of the tree.
Citrus sinensis (sweet orange)-- Praticollela griseola, snails: Large numbers were found covering trunks of trees in a citrus grove (Hendry County; E98-2005; John McGuire, grove manager, Phillip A. Stansly, University of Florida's Southwest Florida Research and Extension Center, Immokalee; 18 June 1998). These snails can rasp leaves but normally they are not significant pests (Dr. Lionel A. Stange).
Citrus spp. (mixed citrus cultivars)-- Diaphorina citri Kuwayama, Asian citrus psyllid: A slight infestation was found at a discount store in Oakland Park (Broward County; E98-1913; James 'Keith' Harris; 12 June 1998).
WEEDS AND GRASSES: Artemisia ludoviciana (mugwort)-- Coloradoa artemisiae (del Guercio), an aphid: A moderate infestation was found on a plant at a botanical garden in Gainesville (Alachua County; E98-972; Dr. Susan E. Halbert and Belén Belliure; 11 April 1998). This is a widely naturalized Eurasian species (Dr. Susan E. Halbert). NEW DPI FLORIDA STATE RECORD.
BENEFICIAL INSECTS: Aonidiella orientalis (Newstead) (Oriental scale) -- Closterocerus phenacapsia (Yoshimoto), a eulophid parasitic wasp: The parasite was found in a laboratory colony of Oriental scale on Cycas circinalis (queen sago) at a United States Department of Agriculture research unit in Miami (Miami-Dade County; E98-1249; Holly B. Glenn, University of Florida's Tropical Research and Extension Center, Homestead; 18 March 1998). NEW HOST RECORD FOR THIS PARASITE (Dr. Gregory A. Evans).
Philephedra tuberculosa Nakahara & Gill (a scale insect)-- Curinus coeruleus Mulsant, a ladybird beetle: Beetles were found eating scales on Dombeya sp. (a tropical snowball) at a residence in Deerfield Beach (Broward County; E98-1548-2; M. Ernst, homeowner, and Dennis C. Clinton; 21 May 1998).
-- Diomus sp., a ladybird beetle: Beetles were found eating scales on Dombeya sp. (a tropical snowball) at a residence in Deerfield Beach (Broward County; E98-1548-3; M. Ernst, homeowner, and Dennis C. Clinton; 21 May 1998).
-- Exochomus marginipennis (LeConte), a ladybird beetle: Beetles were found eating scales on Dombeya sp. at a residence in Deerfield Beach (Broward County; E98-1548-1; M. Ernst, homeowner, and Dennis C. Clinton; 21 May 1998).
FEDERAL/STATE PLANT PROTECTION AND QUARANTINE PROGRAMS: Ceratitis capitata (Weidemann), Mediterranean fruit fly (medfly): seven wild flies were detected in a Jackson trap in a residential area of Bradenton (Manatee County; E98-1324; Frank Brown, United States Department of Agriculture; 12 May 1998). Surrounding the find, large numbers of detection traps were placed in a grid according to protocol guidelines. At the time of the last detection (June 14), a total of 660 flies had been captured at 99 sites in and around Bradenton and Palmetto. Much of the control operation was conducted on the ground, but three aerial applications of malathion bait spray were also applied over a total of 40 square miles. The last aerial spray in Manatee County was 25 June. Sterile flies were initially released in areas surrounding the chemical treatment areas. Release areas were then expanded into the core infestation areas after completion of bait treatments and extended to the whole corridor west of I-75 in Hillsborough, Pinellas, Manatee and Sarasota counties.
No additional wild flies were detected in Miami Springs (Dade County). Release of sterile flies continued throughout the reporting period for a total duration of nearly three life cycles.
In Lake county, the last wild medfly detection was on 17 June, making a total of 1,315 flies. The last of seven aerial applications of bait spray over 35 square miles was completed on 13 June. Ground application of bait spray will continue for four additional weeks only in the one-square mile surrounding the final detection site (Dr. Gary J. Steck).
Gromphadorhina sp., a hissing cockroach: Sixty-four adults and juveniles in a large container were seized at a nursery in Bradenton (Manatee County; E98-1243; L. Wayne Clifton and Mark L. Runnals; 1 May 1998).
INSECT DETECTION: Androchrus femoralis (Olivier), a comb-clawed beetle: A specimen was collected in Gainesville (Alachua County; E98-1106; Joseph S. Beckwith; 19 April 1998). This is an interesting and uncommon beetle (Dr. Michael 'Mike' C. Thomas).
Aethina tumida Murray, the small hive beetle: Specimens of this South African honeybee pest were submitted for identification by a St. Lucie County beekeeper on 1 June 1998. An immediate survey revealed it to be present in hives in six Central Florida counties: Brevard, Indian River, Lake, Martin, Polk, and St. Lucie. Although not considered a serious problem in South Africa, infestations of this beetle have already killed hives in Florida (Dr. Michael 'Mike' C. Thomas). NEW WESTERN HEMISPHERE RECORD.
Cachryphora serotinae (Oestlund), a goldenrod aphid: A specimen was collected in a suction trap in Quincy (Gadsden County; E98-1090; Dr. Richard K. Sprenkel, University of Florida's North Florida Research and Extension Center, Quincy, and Dr. Susan E. Halbert; 17 April - 1 May 1998). NEW DPI COUNTY RECORD.
Capitophorus jopepperi Corpuz-Raros & Cook, a ragweed aphid: A specimen was collected in a suction trap in Ft. Pierce (St. Lucie County; E98-1089; Dr. Robert C. Bullock, University of Florida's Indian River Research and Extension Center, Ft. Pierce; 17-24 April 1998). NEW DPI COUNTY RECORD.
