There have been substantial numbers of fruit flies trapped in California during the year 2001. By year's end there had been 15 different eradication programs started for five different Tephritid fruitfly species. However, larvae (the actual indication of an infestation) were collected only once. While most of the fruitfly finds occurred after July, only those collections made prior to June 30 will be recorded in this issue of CPPDR. The other finds will be listed in the July - December issue.

MEDITERRANEAN FRUIT FLY, Ceratitis capitata -(A)- A single adult female Medfly was collected in Los Angeles County during this time period. See the chart on page 4 for more details. As of June June 30, no Medfly infestation existed.

MEXICAN FRUIT FLY, Anastrepha ludens -(A)- Several specimens of this serious fruit fly pest have been trapped in California during the time covered by this report. See the chart on page 5 for more details. However, as of June 30, no infestations exist.

GUAVA FRUIT FLY, Bactrocera correcta -(A)- Several specimens of this serious fruit fly pest have been trapped in California during the time covered by this report. See the chart on page 4 for more details. As of June 30, no infestations existed.

ORIENTAL FRUIT FLY, Bactrocera dorsalis -(A)-Several specimens of this serious fruit fly pest have been trapped in California during the time covered by this report. See the chart on page 5 for more details. At this point, no established infestations were indicated.

OLIVE FRUIT FLY, Bactrocera oleae -(A)- This fly has been collected in many new counties this year. For a listing of trap catches, see the chart on page 5 - 6. For a distributional map of known counties infested with olive fruit fly see page 4.

GYPSY MOTH, Lyrnarrtria dispar, -(A)-One Gypsy moth was trapped during the period of this report. The data is listed on the chart on the next page. No indications of an infestation were found at that site. However, two spray treatment eradication programs were carried out this year due to significant finds last year in Novato, Marin County and Fallbrook, San Diego County.

Brady CPPDR Janual-y-June,2001 Page S NEW STATE RECORDS GREEN CONEHEADED PLANTHOPPER, Acanalonia conica -(a)- Trus plant hopper has been found for the first time in Cahfornia at Carmichael, Sacramento County for a new state record. The collection was made by a homeowner who submitted it to a nearby commercial nursery who in turn submitted it to the Agndtural Commissioner. The initial submission was on June 25, sub- Ag Inspector Lisa Arbegast. Subsequent surveys of the area by Ag Inspector Ramona Saunder and others indcated that the hoppers were found on several adjacent properties, where the habitat was cool and moist with ample shade. Nymphs were collected from euonyrnus, pittosporum and alder. Adults were found commonly on alder, less commonly on roses and cim.

A smular survey by CDFA Entomologst Dck Penrose found that the hopper was established on small willows along Arcade Creek about a rmle west of the on& location. A short time later a specimen was found in a private collection that had been collected in 1994, at a residential site about four miles to the south of the oripal find, again in a cool and shaded location. Dck Penrose has now recollected the hopper from hssite. Shortly after, yet another collection was made four rmles east of the ori& find. The is apparently well estabhhed in the Carmichael area, and perhaps beyond.

The hopper belongs to a family of planthoppers called the Acanaloniidae, one of about 15 famdies of hoppers in the superfamily Fulgoroidea. However, some taxonomist speciahsts in that group feel that these hoppers actually should be included in the family Issidae, and the family Acanaloniidaeshould be dropped. The adult insect is about 8-12 mm long, with wings folded over the back. The color is light green, with a redchh or brown series of spots or a solid thm healong the outer (posterior) edge of the wings (see Figs. 1-2 ). msplanthopper looks very smular to the introduced Austrahan torpedo bug (Sipluznh acuta, farruly Flatidae), but that species Mers because the upper posterior comer of the wings, when at rest over the body, have a very decided upward chrected angle (see Fig. 3 ). The nymphs of A. conica are mottled brown with a very dstinctive hump-backed appearance (see Fig. 4). There are 16 species ofAcanaloniid planthoppers in the U.S. Several are eastern. Two others are apparently native to Cahfornia and there are a number of species in Arizona, A. molliczrla common in Imperial County north to Kern County and A. pndicella known from Imperial to Inyo Counties (seeFigs. 11 & 12 ). These two species Merfrom conica because the face is flat in lateral view, but conically projected forward in conica.

A. conim is native to the southeastern part of the United States, from Florida west to Texas and north to Oho and Indana. It is pdyan arboreal species, and is considered only as a minor, sporadc pest of forests. It has only one generation per year, whch may explain its non-pest status. Its potential in Cahfonua is unknown at hstune. Wdson and McPherson (1981) have published on the Me hstory in the Ann. En tomol. Soc. Amer. 74 (3):289-298.

NEW STATE RECORDS, continued INDIAN WALKING STICK, Carausius morosus -(Q)- Established populations of this insed were found in two areas of a neighborhood in La Jolla, San Diego County for a new state record. The first collection was made by County Entomologist David Kellurn on June 6. Further delimitation found it several blocks away at another location. See the distributionmap on page 11. Apparently the infestations arose from some specimens which were released into the yards of several boys who had raised them as pets. Over 40 properties have been found Infested in La Jolla.

These interesting ins&, kin to the grasshoppersand mantids, belong to theorthoptera farmly Pbmidae, 1though some scientists place them in their own order, Phasmida. This particular species is one that has moved around the country, including California, via the pet industry and in particular has been moved about by teachers in local schools. The are being used by teachers to stimulate student interest in biology. Unfortunately students are apparently taking them home and releasing them into the wild.

As the name implies, this species is native to the Indian subcontinent. Adult specimens range from 2.5 to 3.5 inches in length. One of the distinguishing features of this species is the thin, reddish area of the base of the forelegs ( see Fig. 14). The populations in the US are apparently parthenogenetic, although males are known from other locations. The color is usually green or greenish-brown. They apparently will drop to the ground if disturbed, and are, as a rule, night feeders. So often the only indication of their presence is the feedmg damage, the removal of large amounts of leaf material. Favored hosts seem to be privet, ivy, hawthorne, blackberries, pyracantha and roses. The San Diego populations were primarily on ivy, and they are causing a considerable amount of damage. There are a number of other species of walking sticks that are being raised for the pet trade. There are also a number of websites devoted specifically to the rearing of these creatures, and to testirn01uals to the pleasures and benefits of having colonies of them in captivity

NEW STATE RECORDS, continued NEW ZEALAND MUD SNAIL, Pota-vgus antipodarum -(Q). This snail has been introduced into the United States at an earlier date. It has now been found in California for the first time, however. Personnel associated with the California Department of Fish and Game have reported that they have found this new snail in the Owens &ver, near Mammoth Lakes, Mono County The find was made sometime in early March. The infestation occurs in the Owens River from its confluence with Hot Creek downstream to Lake Crowley Reports are that the river bottom is literally paved with the tiny snails. They range from the size of a grain of sand to only about 1/8th of an inch in length.

The snail is apparently a detritus feeder. It is able to withstand harsh environmental conditions, and apparently can easily survive the digestive systems of fish. It is being spread by fishing equipment; especially in the boot treads of fishing waders.

The infested area of the Owens River is a favored spot for fly fishermen, and this maybe the pathway for its entry into the state. It is currently known from the Snake River in Idaho, Lake Ontario on the US/ Canadian border, the Columbia fiver mouth, the Yellowstone River, and the Gardner River in Montana. Impact on Owens River water quality fishing quality and other factors are unknown at this time. It is under investigation by the Department of Fish and Game.

CPPDR Ianua I-y-June,2001 Page 14 NEW COUNTY RECORDS SPOTTED GUM LERP PSYLLID, Eucalyptolyma maideni-(Q)- This lerp-forming psyllid from Australia has been found for the first time in Ventura County. The collection was made at Port Hueneme on April 4,2001 by Dick Penrose. The host was the spotted gum, Eucalyptus ~?zaculattr.This psyllid was first found in Los Angeles County, and later in Orange County, last year. Like the red gum lerp psyllid, this species is building up large amounts of honeydew. However, the two infested eucalyptus species, spotted gum and lemon gum Eucalyptus mtrct~lataand Ezlcalyptus citriodortr, are planted less commonly. For more information on this psyllid see CPPDR 19(3-6):26-27June -December 2000. GIANT WHITEFLY, Aleurodicus dugesii-(C)- This whitefly has been established in Califor- nia since 1992. For more information see CPPDR Oct-Dec 11 (5-6):78-81. This whitefly has now been found in Imperial County at Calexico. The collection was made on January25 fromguava by collectors Arellano and Hernandez. This brings to six the number of infested counties included in order and year of their first records: San Diego (1992),Orange (1995),Los Angeles (1995), Santa Barbara (1997), and Ventura (1998). This whitefly may become established in other counties, since it has been intercepted a number of times this summer on nursery stock moving out of southern California. It has become a very troublesome pest, with heavy populations and copious amounts of white wax on the leaves, especially on hibiscus and citrus. HAKEA PSYLLID, Acizzia hakea -Q- Tkus psyllid was first found in the state in Santa Barbara County in May 8,2000. For information on tlus find see CPPDR, June -December 19 (3-6): 27-8. The Santa Barbara collection was a new North American record for hsAustrahan insect. The first find was from the plant sheoak (Grevillea) in the famdy Proteaceae. It has now been found for the first time in two other countries, tlus time on Hakea plants, also in the Proteaceae. It has also been collected from Haka in Santa Barbara County, besides the oripal find on Grmillea. New finds include Port Hueneme, Ventura County and Redondo Beach, and Los Angeles County The Ventura County colledon was made by CDFA Detection Entomolopt Dck Penrose on April 5; the Los Angeles collections were made by Los Angeles County Biologst Conrad Burtoa, both in series at Redondo Beach on March 12 and at Torrance on March 28. All collections since the ori@ find on Grmillea at Santa Barbara have been on Hakea, particularly on Hakea s~uzveolens.At hspoint in time there is no indcation of serious damage to the infested plants. EUCALYPTUS PSYLLID, Ctenarytaina spatulata-(Q)- This psyllid has been established in California for a number of years. It is considered by Nick Nisson, Orange County Entomolo- gist, as the most common species of eucalyptus infesting psyllid in that county. It does not, however, appear to cause as much damage to the trees as blue gum or red gum lerp psyllids. It has now bee11 found for the first time in Santa Barbara County. The collection was made at Goleta on April 12 by M. Rajala from Et~calyptl~sctrmtrlduletlsis. INDIAN WALKING STICK, Carazisius morosus -(Q)- This walking stick has recently been found established in California. See the article on the new state record for this insect on page 11. Besides the first find in San Diego, the insect has now been found in Arroyo, San Luis Obispo County. The collection was made County Ag. Biologist Christine Linne on June 29. Specimens could be found all over the yard on the one property. REDGUM LERP PSYLLID, Glycaspis briniblecombei -Q- With the fine of this psyllid in Humboldt County by Baldo Villegas, it probably occurs in all California counties where Eucalyptus will survive, with the possible exception of Del Norte County. See the distribution map on page 15 as of September. NEW COUNTY RECORDS, continued

GREEN SCALE, Coccus viridis -(A)- This soft scale was collected from a nursery in Orange, Orange County on June 19. The collection was made on Dizygotkeca plants by County Ag Inspector James Wynn.

The following pages 17 to 20 indicate a few of the many quarantine interceptions made during the year. The pest species selected for listing were chosen to indicate to quarantine officials and inspectors the kinds of pests that are currently being intercepted in quarantine shipments around the state.

SMALL HIVE , Aethina hrmida -(Q)-This beetle, a sap beetle in the family Nitiduhdae, was intercepted in beehives arriving from eastern locations. The collection was made by Merced County Ag Inspectors Fred Mchaelis and Sean Runyon on March 1. Three specimens were collected. The hives were owned by a Florida-based firm; but, the hives had been in both Maine and South Dakota prior to shpment to Cahfornia.

The genus Aetkina contains about 30 species, the majority of which are African and Asian. About four or five species are endemic to the Western Hemisphere, ranging from Mexico to Central and South America. The small hive beetle is native to Africa. During 1998, Florida's first year of infestation, beekeepers lost over 40,000 hives. Last year, those loses were nearly zero. While beekeepers are managing the problem it is still reported to be a problem in honey houses.

The map on the next page shows the known htribution of SOD as of June 30,2001. The disease has been found on a number of other native and introduced hosts in the area where it has lulled a number of oak trees. This includes Rhododendron nzacrophyllum, Manzanita (Arctostnphylos), California huckleberry (Vaccinium uuatum), madrone (Arbutus menziesiz], California bay laurel (Umbellularia californicrz),Cahfornia buckeye (Aesculus californica),and big leaf maple (Acer macruphyllum). The hosts other than oak are often not lulled by the fungus, but are may or may not be symptomatic and probably serve as a source of inodum to other, non-infected oaks. EXCLUSION DAnILY RUST, Puccinia hemerocallidis -(Q)- Trus federally actionable fungal pest of daylhes has been intercepted in Cahfornia nurseries on shpments oriptingin Florida. Collections were made in Fallbrook, San Diego County by Ag. Inspector Jim Lawrence; at Carson, Los Angeles County by Ag. Inspector Burton; and at Long Beach, Los Angeles County by CDFA Plant Pathologst Magally Luque- W&m. As a result of the finds, 51,000 plants were destroyed at the Fallbrook location, and 2500 plants were destroyed at the Los Angeles locations.

Daylhes mfected with Puccirzia hemerocallldis have now been cohedfrom nine states ( AL, CA, FL, GA, LA, MN, MS, SC, TN). At least 10 -15 susceptible daylily varieties have been found. The distribution of I? '!erocnllidis is widespread and hobbylst movement of Infected daylhes is d~ffialtto restrict.

The rust occurs in Costa Rca, where daylhes have been shpped from Florida for propagation for at least 10 years. The daylhes are then shipped back to the U.S., usually to nurseries in Florida which in turn, &tribute them to other states, hke Cahfornia. Much of th~daylily material has the leaves removed before shpping, increasing the &dty of detecting I? '!hemerocallidis on the plants. Costa Rca would welcome technology transfer assistance from APHIS in controhng I? '!erocalldis, because they lose money when mfected shpments are returned or destroyed. Other Latin American daylily growers such as Guatemala could also possibly be assisted.
