ENTOMOLOGY SECTION
Compiled by Susan E. Halbert, Ph. D.
For the month of May, there were 612 samples, consisting of 9,800+ specimens. In June, there were 432 samples, consisting of 1,5437+ specimens. Some of the samples processed are listed below:
ORNAMENTALS, WOODY PLANTS AND PALMS: Capparis cynophallophora (Jamaica capertree, a native species)-- Dichogama redtenbacheri Lederer, a pyralid moth: A severe infestation was found at a research unit in Homestead (Miami-Dade County; E2001-2215; Holly B. Glenn, University of Florida's Tropical Research and Extension Center-Homestead; 22 November 2000).
ORNAMENTALS, FOLIAGE PLANTS: Codiaeum variegatum var. pictum (croton)-- Asprothrips seminigricornis (Girault), a thrips: A moderate infestation involved 40 of 50 plants at a nursery in Miami (Miami-Dade County; E2001-1321; Duraid I. Hanna; 29 March 2001). NEW DPI COUNTY RECORD.
ORNAMENTALS, FLOWERING PLANTS: Orchidaceae (an orchid)-- Conchaspis angraeci Cockerell, angraecum scale: A severe infestation was found on a plant at a nursery in Naples (Collier County; E2001-2145; Scott D. Krueger; 21 May 2001).
Viburnum macrocephalum (Chinese snowball)-- Ceruraphis eriophori (Walker), a viburnum aphid: A slight infestation was intercepted on cut flowers at a flower dealership in Orlando (Orange County; E2001-1990; Terrence D. Williams; 7 May 2001). This aphid has been intercepted at several ports of entry this year on shipments of cut flowers from Europe. This relatively obscure European species uses Viburnum as a winter host and various sedges as summer hosts. In the U.S., it is established in the Pacific Northwest, but not in Florida. The specimens I have seen from interceptions have been winged or alatoid nymphs, and thus there is potential for dispersal and colonization in North America. Although not likely to be a serious plant pest, C. eriophori occasionally transmits barley yellow dwarf virus. This shipment was accompanied by Orius insidiosus (Say), minute pirate bugs. Frequently, the presence of these highly visible tiny predators can indicate a plant pest problem in the shipment (Dr. Susan E. Halbert).
FOREST AND SHADE TREES: Bucida buceras (black-olive)-- Paratachardina lobata (Chamberlin), a lac scale: A moderate infestation was found at a nursery in Miami (Miami-Dade County; E2001-2442; Edward T. Putland; 11 June 2001).
Eucalyptus sp. (a eucalyptus)-- Blastopsylla occidentalis Taylor, a eucalyptus psyllid: An infestation was found at an amusement park in Orlando (Orange County; E2001-1989; Barbara J. Wilder; 9 May 2001). This psyllid is not as damaging as the red gum lerp psyllid discovered in a Florida amusement park in April. Damage consists of wax-covered infestations on new growth (Dr. Susan E. Halbert). NEW DPI STATE RECORD.
Ficus sp. (a ficus)-- Cligenes distinctus Distant, a seed bug: A specimen was recovered from leaf litter under fruiting ficus in Ft. Pierce (St. Lucie County; E2001-2589; Kenneth L. Hibbard; 22 June 2001). NEW DPI COUNTY RECORD.

Richardia scabra (Mexican-clover, Florida pusley)-- Tetranychus ludeni Zacher, a spider mite: A severe infestation was found in Apopka (Orange County; E2001-1909; Dr. Lance S. Osborne, University of Florida's Mid- Florida Research and Extension Center-Apopka; 4 May 2001). This is not a common spider mite in Florida (Dr. W. C. 'Cal' Welbourn).
BENEFICIAL INSECTS: Montandoniola moraguesi (Paton), a pirate bug: Specimens were found feeding on Nesothrips sp. on Ficus aurea (strangler fig) along a roadside in Homestead (Miami-Dade County; E2001-2090; Edward T. Putland; 15 May 2001). This rare predator also may feed on Gynaikothrips ficorum on Ficus spp. NEW DPI COUNTY RECORD. (Dr. Susan E. Halbert and Dr. G.B. Edwards).
FEDERAL/STATE PLANT PROTECTION AND QUARANTINE PROGRAMS: Eucalyptus cinerea (silver-dollar eucalyptus)-- Helix aspersa Müller, brown garden snail: Specimens were found in cut flowers from California at a wholesale business in Tampa (Hillsborough County; E2001-2041; James R. Martin; 14 May 2001.
Lactuca sativa (lettuce)-- Helix aspersa Müller, brown garden snail: A specimen was found in lettuce from California at a store in Tampa (Hillsborough County; E2001-1780; Howard L. Wallace and Terri L. Gater; 3 May 2001).

Bactrocera correcta (Bezzi), guava fruit fly: A specimen was found in a Cuelure-baited Jackson trap in a loquat tree in Apopka (Orange County; E2001-1858; Katherine A. Gonzalez; 4 May 2001). These flies are attracted to methyl eugenol (ME), which was present in another trap on a nearby tree on the same property. Survey activities were increased in the area, but no control activities implemented. No additional flies were detected. Two flies of this species were detected for the first time in Florida in August 1999 (Dr. Gary J. Steck).
Bactrocera dorsalis (Hendel) complex, oriental fruit fly complex: A specimen was found in a methyl eugenol-baited Jackson trap in and unknown host tree in Kissimmee (Osceola County; E2001-2462; Larry Byrd, USDA; 12 June 2001). Using protocol guidelines, large numbers of methyl eugenol and McPhail detection traps were placed in a grid surrounding the find. To date, no further flies have been detected in this area; hence, no eradication efforts were undertaken (Dr. Gary J. Steck).
ARTHROPODS OF MEDICAL AND VETERINARY IMPORTANCE: Dermatobia hominis (L., Jr.), bot fly: A single larva was extracted from a patient who had traveled to Belize and returned to Winter Park (Orange County; E2001-2056; Tolliver Higgins, M.D.; 8 May 2001). Female bot flies lay their eggs on biting flies such as mosquito or stable flies. These biting flies then transport the bot fly eggs to various mammalian hosts, including man, where the eggs hatch, bore into the host, and develop subcutaneously (Dr. Gary J. Steck).
Heteropoda venatoria (Linnaeus), giant crab spider: A specimen was found at a residence in Sarasota (Sarasota County; E2001-2233; Phillip G. Baioni; 23 May 2001). This cockroach predator is moderately toxic and can cause considerable swelling. This introduced pantropical species is primarily a house spider, except it is feral in the southern half of Florida (Dr. G.B. Edwards).
Loxosceles reclusa Gertsch & Malaik, brown recluse spider: Three specimens (one male, one female, one juvenile) were found in the basement of the Conradi Biology building at Florida State University in Tallahassee (Leon County; E2001-2330, 2331; T. David Gowan, Florida State University; 30 April 2001, 10 December 2000). An additional male and one juvenile were located in the same building (Leon County; E2002-2747; Dr. G.B. Edwards; 26 January 2001).
APIARY PESTS: Aethina tumida Murray, small hive beetle: An infestation was found in a hive in Pensacola (Escambia County; E2001-1498; C. Douglas Corbin, Apiary; 12 March 2001). NEW DPI COUNTY RECORD.
INSECT DETECTION: Achaearanea geochares Levi, a cobweb spider: A specimen in a shipment of liners from California was intercepted in St. Cloud (Osceola County; E2001-1846; Terrence D. Williams; 1 May 2001). The spider is definitely from California (Dr. G.B. Edwards).
Gasteracantha cancriformis (Linnaeus), a spinybacked orb weaver: Several specimens in a shipment of citrus fruit from the Bahamas were intercepted in Ft. Pierce (St. Lucie County; E2001-2046; James J. Walukiewicz; 9 May 2001). Two specimens were the black color form that does not occur in Florida, but is common in the Bahamas (Dr. G.B. Edwards).
Geocoris floridanus Blatchley, a bigeyed bug: A specimen was found under Mentzelia floridana, preying on other lygaeids in Playa Linda Beach (Brevard County; E2001-2466; Kenneth L. Hibbard, Gregory A. Brown, Julieta Brambila, and Dr. Susan E. Halbert; 12 June 2001). NEW DPI COUNTY RECORD.
Geocoris uliginosus (Say), a bigeyed bug: Several specimens were found along US highway 441 between Kenansville and Yeehaw Junction (Osceola County; E2001-2017; Kenneth L. Hibbard; 10 May 2001). NEW DPI COUNTY RECORD.
Griburius equestris (Olivier), a chrysomelid beetle: A specimen was found in a Jackson trap in Bartow (Polk County; E2001-1932; Martha A. 'Ginger' Simpson; 24 April 2001). This is a very rare leaf beetle (Dr. Michael C. Thomas).
Lathys dixiana Ivie & Barrows, a spider: A specimen was found along Florida highway South A1A in Ft. Pierce (St. Lucie County; E2001-1577; Dr. G.B. Edwards and Kenneth L. Hibbard; 19 April 2001). NEW DPI COUNTY RECORD.
Microdipoena guttata Banks, a spider: A specimen was found along Florida highway South A1A in Ft. Pierce (St. Lucie County E2001-1577; Dr. G.B. Edwards and Kenneth L. Hibbard; 19 April 2001). NEW DPI COUNTY RECORD.
Minthea rugicollis Walker, a bostrichid beetle: Specimens in materials imported from China were recovered in St. Petersburg (Pinellas County; E2001-2628; David M. Mooney; 26 June 2001). This beetle is not native, nor established in Florida. It is a bamboo specialist but has been reported from other woods (Dr. Paul E. Skelley).
Opopaea bandina Chickering, a spider: Several specimens, both male and female, were found along Florida highway South A1A in Ft. Pierce (St. Lucie County E2001-1577; Dr. G.B. Edwards and Kenneth L. Hibbard; 19 April 2001). The male is undescribed (Dr. G.B. Edwards).
Osmopleura chamaeropis (Horn), a cerambycid beetle: Two specimens were collected in Winter Haven (Polk County; E2001-2377; Leon H. Hebb; 7 June 2001). This is quite a rare beetle. It is associated with Sabal palmetto (cabbage palm), but usually very hard to find (Dr. Michael C. Thomas).
Sobarocephala quadrimaculata Soos, a fly: A specimen was found in a multilure trap in Sunrise (Broward County; E2001-2453; Paul Moeser, USDA; 8 June 2001). NEW DPI COUNTY RECORD.
Trogoderma sp., a dermestid beetle: A larva in furniture from Tibet was found in Ft. Myers (Lee County; E2001-2592; Lawrence 'Larry' W. Mitchell, FDACS/Division of Agricultural Environmental Services, Ft. Myers; June 2001). This beetle is not the common Trogoderma granarium Everts (Dr. John M. Kingsolver, Research Associate).
