CPPDR lanual-v-lune, 2001 Page 3 ENTOMOLOGY HIGHLIGHTS 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 insect 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.
