TRI-OLOGY’s New Look
As our 47th year of publicationof TRI-OLOGY approached, wewanted to improve our abilityto inform our readership of thediagnoses and identificationsdone by our division’staxonomic scientists. Afterhaving edited TRI-OLOGY for16 years, I was ready for achange in our look and deliverysystem. I requested assistancefrom several co-workers toassist in this opportunity tochange. We recognized thatimproved use of the Internetwas achievable and wouldimprove access to the scientificdeterminations of pests andpathogens found on ouragricultural and native plantresources.
I would like to thank severalco-workers for their ableassistance in making thisupgrade possible. First andforemost is Dr. Patti Anderson,who has done an exemplary

HighlightsFollowing are a few of the notable entries from this volume of TRI-OLOGY. These entriesare reports of interesting plants or unusual pests, some of which may be problematic. SeeSection Reports for complete information.
Persea borbonia (red bay) – Raffaelealauricola, laurel wilt. The laurel wilt pathogenvectored by Xyleborus glabratus, redbay ambrosiabeetle, is capable of attacking and killing red bayand several other members of the laurel familyincluding sassafras, pondspice, spicebush andcamphor-tree. Commercially, the biggest concernis the apparent susceptibility of many varieties ofavocado, most of which are grown in Miami-DadeCounty.
Persea humilis Nash. - silk bay, scrub bay. Thethree species of Persea native to Florida are allvery similar in general appearance. Unfortunately,like all of its close relatives, the silk bay istheoretically susceptible to the laurel wilt diseaserapidly being spread by the redbay ambrosia beetle. To date, no infected plantof this species has been found.
Lycium carolinianum Walt. - Christmas berry,Carolina desertthorn, lycium. This species is aspiny, salt-tolerant, evergreen shrub to 2 m tall,found in coastal areas, including shell mounds andthe edges of salt marshes and brackish swamps,from South Carolina to Florida and west to Texasand Mexico.
Phoradendronleucarpum (Raf.)Reveal &M.C.Johnst. - oakmistletoe. Thisevergreen subshrub,up to 1 m in diameter,is a hemi-parasite,taking water and
DPI’s Bureau of Entomology, Nematology and Plant Pathology (the botany section is included in this bureau) produces TRI-OLOGY sixtimes a year, covering two months of activity in each issue. The report includes detection activities from nursery plant inspections, routineand emergency program surveys, and requests for identification of plants and pests from the public. Samples are also occasionally sentfrom other states or countries for identification or diagnosis.

job over the past two and halfyears as our Managing Editor,and clearly guided thistransition to success. Next,Denise Feiber, Director ofTechnical Assistance, and ScottWeinberg, Graphic Artist andwebmaster, who have so aptlytaken our vision and made itreal on screen as well as inprint. Also, Dr. Susan Halbert,Dr. Renato Inserra, Dr. JaneteBrito, Robert Leahy, Dr. TimSchubert, Dr. Cal Welbourn, Dr.Dick Weaver, Cindy Edwardsand Jody Hansen contributedsignificantly to our upgrade inmany different ways, makingsure that our scientific staff atlarge had an opportunity toprovide input into ourtransition. I also thank themany contributingphotographers.
As we move forward in betterusing today’s technology, I amreminded that TRI-OLOGY firstappeared in 1962 as atechnical report of news andother notes from theEntomology, Nematology andPlant Pathology bureaus. Thereport was prepared on atypewriter and copies were putin the mail to interestedreaders. At one time, wemailed over 800 copies everytwo months to a worldwidereadership. It took up toseveral months for TRI-OLOGYto reach some of our readers.Now, the retrieval time isinstantaneous after a TRI-OLOGY report is posted to ourwebsite, and we hope ourreaders will find theirinformation needs met througheither the provided overviewsor needed details in linkedancillary tables.
I suspect we will continue totweak our upgrade a bit over

nutrients from its host tree, but also carrying outphotosynthesis. Only one other species in thisgenus occurs in Florida, P. rubrum, the mahoganymistletoe. It is a rare, parasitic plant found only in
far South Florida, distinguished from oak mistletoe by its lemon-yellow toorange fruit.
Carthosilvanus vulgaris (Grouvelle). Specimens werecollected in a blacklight trap at the Port Manatee ForestryTerminal by Customs and Border Patrol. This is aNeotropical species not previously known from the UnitedStates; the collection is a continental record. This beetle isnot of economic importance. It lives under bark and feedson fungi. (Dr. Michael C. Thomas.)
Orius tristicolor (White) minute pirate bug. Found onHelianthus debilis, beach sunflower or dune sunflower inTierra Verde, FL. This is the second catch for the tinypredator (usually no more than 3 mm long) in thelandscape in Florida. It is intercepted regularly on producefrom Western states. This is a county record for Pinellas.(Dr. Susan E. Halbert.)
Solanum viarum (tropical sodaapple) – Meloidogyne javanica(Treub, 1885) Chitwood, 1949,the Javanese root-knotnematode was found infecting the roots of this noxiousweed during a survey by DPI staff. Roots were heavilyinfected and deformed by prominent and bead-likegalls. Root-knot nematodes have broad host ranges andare very damaging pathogens of many agronomic andhorticultural crops including most row and vegetablecrops, fruit trees and ornamental plants.
Miscanthus sinensis (zebra grass, Chinese silvergrass) - Pratylenchus zeae Graham, 1951, a rootlesion nematode was found infecting the roots of thisornamental grass. Nematode-infected roots showeddark lesions on their surface. Morphological andmolecular (rDNA) analyses were used for species
identification. As this ornamental grass becomes more popular in Florida, itspests may become more economically important.
Dracaena sanderiana (lucky bamboo) –Colletotrichum dracaenophilum, stem rot. This stempathogen has probably been introduced into the UnitedStates by way of the vast quantities of lucky bamboopropagative material imported from Asia.
Hibiscus syriacus (rose-of-Sharon) – Thielaviopsisbasicola, root rot. The black root rot pathogen is morecommonly found on hollies and pansies, but has a widehost range. It prefers wet, cool soils and can be verydifficult to manage after soils are infested. NEW HOST

Descurainia pinnata (Westerntansymustard)Photograph courtesy of J. Lotz, DPI
Botany SectionCompiled by Richard E. Weaver, Jr., Ph.D., and Patti J. Anderson, Ph.D.This section identifies plants for the Division of Plant Industry, as well as for othergovernmental agencies and private individuals. The Botany Section maintains areference herbarium with over 10,000 plants and nearly 1,500 vials of seeds.
Descurainia pinnata (Walt.) Britt. (a genus of 40 species fromtemperate and cool regions, including Europe, South Africa andNorth America). Cruciferae (or Brassicaceae). Westerntansymustard. This is a widespread, weedy, annual herbaceous plant,usually seen flowering in late winter or early spring, in turf, open fields andwaste places with sandy soils throughout the United States and into Mexicoand Canada. This species usually reaches a height of 25-50 cm, with singleor multiple stems that often branch. The stem and leaves are graypubescent, and the deeply dissected leaves are pinnatifid. The flowers occurin terminal racemes, each flower with four yellow, yellow-green or whitepetals. The fruits are narrow siliques, up to 15 mm long and 2-4 mm wide,on pedicels that can reach 1.5 cm in length. Seeds are less than 1 mm long.This is a variable species with several recognized subspecies. Native peoplesthroughout its range used the seeds as food, and some mixed the plant withiron pigments to prepare a dye. (Nassau County; B2009-62; Flewellyn W.Podris; 12 February 2009.) (Austin 2004; Murphy 1996;http://www.fs.fed.us/database/feis/plants/forb/despin/all.html.)
Ilex latifolia Thunberg. (a nearly cosmopolitan genus ofapproximately 400 species, particularly diverse in temperate andtropical Asia and America). Aquifoliaceae. Lusterleaf holly. Thismagnificent evergreen tolerates well the heat of summers in northern andcentral Florida, yet it is barely known and rarely planted here. It is native toJapan and has been in cultivation in this country since 1840. A dense,pyramidal tree to 10 m tall, it is texturally similar to Magnolia grandiflora.The leathery leaves are lustrous dark green above and yellowish beneath,oblong to elliptic with an abrupt, sharp tip, coarsely serrate but not spiny onthe margins and 10-20 cm long. Like all hollies, male and female flowersare borne on separate trees (dioecious). The dark red fruits are about 8 mmin diameter, and they are borne in dense, axillary clusters that completelyencircle the twigs. The fruits persist through the winter, if the robins andmockingbirds miss them, but the color generally fades considerably. Thetrees are difficult to propagate, perhaps partially explaining why they are sorare in cultivation. (Submitted by the general public; 6 January, 2009.)(Dehgan 1998; Dirr 1990.)
Lycium carolinianum Walt. (a genus of about 100 species of shrubsfrom warm temperate regions, primarily the Americas). Solanaceae.Christmas berry, Carolina desertthorn, lycium. This species is a spiny,salt-tolerant, evergreen shrub to 2 m tall, found in coastal areas, includingshell mounds and the edges of salt marshes and brackish swamps, from

South Carolina to Florida and west to Texas and Mexico. The clustered,fleshy, simple leaves grow up to 2 cm in length, have entire margins andare linear to narrowly oblanceolate. The flowers, growing singly, have acalyx with four lobes and a blue to lavender (sometimes pale enough toappear white) corolla with four fused petals. The fruit is an ellipsoid berrythat turns bright red when ripe, usually in December. Although somespecies in this family contain toxins, there are some reports that theChristmas berry fruit is edible, like other members of the family, such astomatoes and peppers. Without doubt, this species is an excellent food forwildlife including nectar-feeding insects and fruit-eating birds as well asdeer, raccoons and other wildlife and makes an excellent addition to acoastal landscape. (Pinellas County; B2009-29; Olga Garcia; 18 January2009.) (Godfrey 1988; Huxley 1992; Nelson 2003;http://www.wildflower.org.)
Persea humilis Nash. (a genus of ca. 200 species in the Asian andAmerican tropics). Lauraceae. Silk bay, scrub bay. The three speciesof Persea native to Florida are all very similar in general appearance, as wellas in many characters of the foliage, flowers and fruits. They differ primarilyin habitat preference and in the hairs (pubescence) on their variousstructures, but most conspicuously on their twigs and the undersides of theirleaves. Considered by some taxonomists to be merely a variety of thecommon red bay, Persea borbonia (L.) Spreng., the silk bay, discussed here,forms a suckering shrub or small tree to 3 m tall with twigs that are denselycovered by rusty hairs. The aromatic, leathery evergreen leaves are usuallynarrowly elliptic to lanceolate in outline and 5-9 cm in length. Theundersides of the leaves are reddish brown due to a dense covering of veryfine, appressed silky hairs. With proper lighting and magnification, thesehairs glisten like short golden threads. As in the other two species, the smallgreenish flowers are borne in slender-stalked axillary clusters, and they arefollowed by roundish, black or blue-black drupes. The silk bay is restrictedin its distribution to scrub habitats in Central and southern Florida, fromAlachua and Putnam Counties south to Martin and Collier Counties.Unfortunately, like all of its close relatives, the silk bay is theoreticallysusceptible to the laurel wilt disease rapidly being spread by the redbayambrosia beetle. However, no infected plant of this species has been found.(Submitted by the general public; 9 January 2009.) (Godfrey 1988;Mabberley 1997; Note: redbay ambrosia beetle pest alert available athttp://www.doacs.state.fl.us/pi/enpp/ento/x.glabratus.html.)
Phoradendron leucarpum (Raf.) Reveal & M.C.Johnst. (a genus ofca. 190 species from the Americas with a concentration in thetropics). Viscaceae (formerly Loranthaceae; recently proposed asSantalaceae). Oak mistletoe. This evergreen subshrub, up to 1 m indiameter, is a hemi-parasite, taking water and nutrients from its host tree,but also carrying out photosynthesis. Heavy infestations of P. leucarpum can

reduce the growth of host trees. The leathery, opposite obovate leaves are2-5 cm long, with entire margins and rounded apices. The flowers areunisexual, with staminate and pistilate flowers on separate plants. Theseinconspicuous flowers are borne on opposite sides of a jointed spike, withfemale flowers developing into clusters of ten or more fruits. Each waxywhite fruit is 4-6 mm in diameter, with sticky (viscous) flesh, and contains asingle seed. Seeds germinate on tree branches, attached there by the stickyfruit pulp. Only one other species in this genus occurs in Florida, P. rubrum,the mahogany mistletoe. It is a rare, parasitic plant found only in far SouthFlorida, distinguished from oak mistletoe by its lemon-yellow to orange fruit.Lore about mistletoe, including the tradition of a kissing under it, began withthe European Viscum album, a species similar to the North Americanmistletoe, but with fewer fruits in each cluster. Both are considered toxic tohumans if eaten, although native peoples of eastern North America haveused mistletoe extracts medicinally as treatment for a variety of ailmentsfrom headaches to whooping cough to ring worms. (Sumter County; B2009-40; Lorrie R. Rigby; 28 January 2009. Palm Beach County; B2009-41; SallieH. Simmons; 29 January 2009. Volusia County; B2009-42; Albert E. “Bud”Mayfield; 4 February 2009.) (Austin 2004; Godfrey 1988; Mabberley 1997;Wunderlin and Hansen 2003; http://en.wikipedia.org/wiki/Phoradendron;http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7437.html.)
Poinsettia heterophylla (L.) Klotzsch & Garke ex Klotzsch, (a genusof 11 species native to warm parts of the Americas, usually includedin Euphorbia). Euphorbiaceae. Mexican fireplant, fiddler’s spurge.Like most members of the Euphorbia family, this plant exudes a milky latexif any piece is broken or detached. This latex may cause dermatitis insensitive people and may have unpleasant effects if ingested. The plant isan annual, pantropical weed closely related, but not very similar in generalappearance, to the ubiquitous Christmas decoration, Poinsettia pulcherrima.It grows to about 1 m tall with (usually) unbranched stems. The specificname “heterophylla” meaning “with different leaves” is appropriate since theleaves are extremely variable. They range from ovate and elliptic tonarrowly lanceolate in outline; entire, with a few coarse teeth or withshallow lobes along the margin; dull green or gray-green above, often withsmall, irregularly spaced purple spots; and from 4-15 cm long and 0.5-5 cmbroad. As in the florist’s poinsettia, modified leaves (bracts) subtend theinflorescence. However, in this species, they are basically colored like thefoliage leaves, but occasionally white at the base or with purple spots. Theflowers themselves lack petals and sepals and are borne in specializedstructures called cyathia, characteristic of Euphorbia and a few closelyrelated genera. According to Dressler (1961), Poinsettia heterophylla isnative from Arizona south throughout tropical America and adventiveelsewhere. Wunderlin and Hansen (2003) and most other sources consider itto be native also in Florida. It usually grows in disturbed habitats butseldom becomes a pest, although it is currently on Florida’s list of noxiousweeds (DPI Rule 5B-57.007), under the synonym Euphorbia prunifolia. Itsinclusion on the noxious weed list is under review. (Miami-Dade County;B2009-36; Stephen P. Beidler; 27 January 2009.) (Dressler 1961;Wunderlin and Hansen 2003.)

Nematology SectionCompiled by Janete A. Brito, Ph.D., and Renato N. Inserra, Ph.D.This Section analyzes soil and plant samples for nematodes, conducts pest detectionsurveys and provides diagnosis of plant problems, in addition to completingidentification of plant parasitic nematodes involved in regulatory and certificationprograms. State of Florida statutes and rules mandate the principal part of theregulatory activity of the section. Analyses of plant and soil samples include those fromin-state programs, plant shipments originating in Florida destined for other states andcountries, as well as samples intercepted in Florida from outside the United States.
Nematodes of Special InterestSolanum viarum (tropical soda apple) – Meloidogyne javanica(Treub, 1885) Chitwood, 1949, the Javanese root-knot nematodewas found infecting the roots of this noxious weed during a survey by DPIstaff. Roots were heavily infected and deformed by prominent, bead-likegalls. In November 1994, this species was found on tropical soda apple inWalton County and reported in TRI-OLOGY. At that time, it was noted that"unlike cultivated crops, tropical soda apple was not severely damaged bythe population of Javanese root-knot nematode." A root-knot nematode inthe same genus (M. arenaria) was recently reported on tropical soda applewith a similar concern that the plant will serve as a reservoir for a knownpest of garden tomatoes and many other hosts. Although these species ofroot-knot nematodes have been found reproducing on the tropical sodaapple, they are not biological control agents and should not be used assuch. Root-knot nematodes have broad host ranges and are very damagingpathogens of many agronomic and horticultural crops including most rowand vegetable crops, fruit trees and ornamental plants. DPI continues itsactive monitoring of this and other pest plants. (Volusia County, N09-00100, Kenneth L. Hibbard, 28 January 2009; Lake County, N09-00170,Leslie J. Wilbur, 11 February 2009.) (Church and Rosskopt 2005; Inserra,R.N. 1994; http://www.gri.msstate.edu/research/ipams/ipams.php.) (DPIcircular No. 27 - Tropical Soda Apple Solanum viarum)
Miscanthus sinensis (zebra grass, Chinese silver grass) -Pratylenchus zeae Graham, 1951, a root lesion nematode was foundinfecting the roots of this ornamental grass. Nematode-infected rootsshowed dark lesions on their surface. Morphological and molecular (rDNA)analyses were used for species identification. As this ornamental grassbecomes more popular in Florida, its pests may become more economicallyimportant. (Santa Rosa County, N09-00152, William L. Robinson, 5February 2009.)

Plant Pathology SectionCompiled by Robert LeahyThis section provides plant disease diagnostic services and conducts a citrusgermplasm introduction program. The agency-wide goal of protecting Floridaagriculture very often begins with accurate diagnosis of plant problems. Diseasemanagement recommendations are offered where appropriate and available. Our plantpathologists are dedicated to keeping informed about plant diseases outside Florida inorder to be prepared for potential introductions of new pathogens.
Persea borbonia (red bay) – Raffaelea lauricola, laurel wilt. Collectedat a private home in Volusia County on 23 January 2009. The laurel wiltpathogen vectored by Xyleborus glabratus, redbay ambrosia beetle, iscapable of attacking and killing several members of the Lauraceae inaddition to red bay, including sassafras, pondspice, spicebush and camphor-tree. Commercially, the biggest concern is the apparent susceptibility ofmany varieties of avocado, most of which are grown in Miami-Dade County.
Dracaena sanderiana (lucky bamboo) – Colletotrichumdracaenophilum, stem rot. Collected at a grocery store in Duval Countyon 9 February 2009. This stem pathogen has probably been introduced intothe US by way of the vast quantities of lucky bamboo propagative materialfrom Asia.
Hibiscus syriacus (rose-of-Sharon) – Thielaviopsis basicola, rootrot. Collected at a nursery in Gilchrist County on 20 January 2009. Theblack root rot pathogen is more commonly found on hollies and pansies, butit has a wide host range. The fungus prefers cool, wet soils and can be verydifficult to manage once soils are infested. NEW HOST RECORD.
Suriana maritima (bay cedar) – Rhizoctonia sp., root rot. Collectedfrom a nursery in Palm Beach County on 12 January 2009. NEW HOSTRECORD.
