Following the first discovery of the disease, the NPPO performed surveys across the whole of Latvia. Approximately 2000 inspections were carried out and 700 symptomatic samples were collected. At present, 7 outbreaks of fireblight have been identified in 4 districts: 6 outbreaks in Zemgale region (Bauska, Dobele and Jelgava districts), 1 outbreak in Vidusdaugava region (Jēkabpils district). Fireblight was found on Malus, Pyrus and Crataegus plants, mainly in private gardens but also in 4 commercial orchards and 1 research centre. Phytosanitary measures are being taken to eradicate the disease by destroying infected plants and surrounding host plants. Further investigations are being made. The status of Erwinia amylovora in Latvia is officially declared as follows: Present, under eradication. Source: NPPO of Latvia, 2007-08. Additional key words: first record Computer codes: ERWIAM, LV 2007/146 Incursion of Diabrotica virgifera virgifera in Germany The NPPO of Germany recently informed the EPPO Secretariat of the first incursions of Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae – EPPO A2 List) in Baden- Württemberg and Bayern. On 2007-07-03, a male adult of D. virgifera virgifera was caught for the first time in a pheromone trap near the airport of Lahr (South-West of Baden- Württemberg) and in total 6 beetles were later caught in this area. On 2007-08-14 and 08- 16, a total of 4 adults were trapped in a maize field close to a harbour along the Danube river next to Passau (Bayern), and on 2007-08-17, one specimen was trapped in the close vicinity of the airport of Munich (Bayern). On 2007-08-22, 19 adults were caught at Salem- Rickenbach (Lake of Constance, Baden-Württemberg). In all areas concerned, measures have been taken according to Commission Decision 2006/564/EC* and according to the German Guideline for Official Measures against D. virgifera virgifera in order to eradicate the infestations. The status of Diabrotica virgifera virgifera in Germany is officially declared as follows: Transient; actionable, under eradication. _____________ * Commission Decision 2006/564/EC of 11 August 2006 amending Decision 2003/766/EC on emergency measures to prevent the spread within the Community of Diabrotica virgifera Le Conte. http://www.eppo.org/ABOUT_EPPO/EPPO_MEMBERS/phytoreg/eu_texts/2006-564-EC-e.pdf Source: NPPO of Germany, 2007-09.

In August 2007, close to Heilbronn (Baden-Württemberg), N. formosana occurred at high density in two fields of Allium schoenoprasum (chives) for consumption. Within the 14 days that followed the first discovery of the infestation, all plants were destroyed. The origin of the infestation is not known. The infestation thus far, is being controlled by chemical treatment.

During a survey in June 2007, 276 specimens were caught on yellow sticky traps in sour cherry orchards (Prunus cerasus) in a rather small production area near the villages Lahonci, Desnjak and Savci (eastern Slovenia). A single specimen was also caught near the village of Radmožanci, close to the Slovene-Hungarian border. The identification of the pest was done by the officially approved laboratory of the Regional Agricultural Institute in Nova Gorica. The origin of the introduction of R. cingulata into Slovenia remains unknown, but the most plausible pathways are via the transport of infested fruits and the natural spread of the fruit fly within Europe*. After these first positive results, the monitoring will be intensified in 2008 to determine the extent of the infestation in Slovenia. The status of Rhagoletis cingulata in Slovenia is officially declared as follows: Present, at low prevalence in eastern part of Slovenia. ______________ * In the EPPO region, the presence of R. cingulata has also been reported from: Germany, Hungary, Italy (Ticino), Netherlands, Switzerland (see EPPO RS 2004/087, 2006/003, and 2007/107).

After the detection of PSTVd in ornamental plants notified by the Dutch NPPO (see also EPPO RS 2006/142), a follow-up inspection was done at a Slovenian place of production in October 2006 and one plant of Brugmansia cordata (Solanaceae) was found positive. During a monitoring survey, 3 EPPO Reporting Service – Pests & Diseases 9 samples of Solanum jasminoides also tested positive in December 2006. An official survey was imposed in 2007, and as a result 29 samples of S. jasminoides and 1 sample of Solanum rantonnettii were found positive at different places of production. The identification of PSTVd was done by the officially approved virological laboratory of the Agricultural Institute of Slovenia. A two step RT-PCR test was used according to the EPPO Diagnostic protocol (EPPO Standard PM7/33(1)). In 2006, all PCR products were sequenced, but afterwards only one sample of S. rantonnettii and several randomly selected samples of S. jasminoides were sequenced. Sequence analyses confirmed the presence of PSTVd. The infection in Brugmansia cordata was also confirmed by the laboratory of the Dutch NPPO. Since in ornamental plants PSTVd infection is symptomless, all registered producers were inspected in spring 2007. Samples were taken from finished pot plants and their mother plants. Eradication measures were imposed: all infected lots and their mother plants were destroyed. Mother plants had been imported in different years: 2000, 2002, 2003 and 2006, and studies are being done to trace the origin of the PSTVd outbreak. The status of Potato spindle tuber viroid in Slovenia is officially declared as follows: Present, only in protected cultivation where host plants are grown, under eradication.

JORDAL Jordal, B.H. 2019. The bark and ambrosia beetle (Coleoptera, Scolytinae) collection at the University Museum of Bergen – with notes on extended distributions in Norway. Norwegian Journal of Entomology 66, 19–31. The bark and ambrosia beetle collection at the University Museum in Bergen has been curated and digitized, and is available in public databases. Several species were recorded from Western Norway for the first or second time. The pine inhabiting species Hylastes opacus Erichson, 1836 is reported from Western Norway for the first time, and the rare speciesPityogenes trepanatus (Nordlinger, 1848) for the second time. The spruce inhabiting species Pityogenes chalcographus (Linnaeus, 1761) and Cryphalus asperatus (Gyllenhal, 1813), which are common in eastern Norway, were recorded in several Western Norway localities. Broadleaf inhabiting species such as Anisandrus dispar (Fabricius, 1792), Taphrorychus bicolor (Herbst, 1793), Dryocoetes villosus (Fabricius, 1792), Scolytus laevis Chapuis, 1869 and Scolytus ratzeburgi Janson, 1856 were collected for the second or third time in Western Norway. Several common species – likely neglected in previous sampling efforts – are well established in Western and Northern Norway.

Each entity has designated a State Survey Coordinator (SSC), with funding received by USDA-APHIS-PPQ (United States Department of Agriculture – Animal and Plant Health Inspection Service – Plant Protection and Quarantine) and administration of funds through UDAF. The Utah CAPS Program has a well-organized committee, with more than twenty members from state and federal agencies. Members specialize in various disciplines, including: entomology, forestry, plant pathology, weed science, agriculture and pesticide usage. The Utah CAPS Committee helps identify emerging priority pests for Utah and also improves sampling techniques for future survey programs. The Committee receives pertinent updates about potential invasive pests throughout the year and at the CAPS Survey Meetings; in 2007, we met in February and May. Other interested parties, such as USU Extension, the Bureau of Land Management and the Utah Nursery and Landscape Association, are also informed about pest activity as needed. Several pest surveys were conducted in 2007, with all data entered into the NAPIS (National Agricultural Pest Information System) as soon as it is received by our Data Entry Manager, Ryan Davis. All available Utah NAPIS data was entered by 31 December 2007 so it could be included in the Western Region CAPS Report.

  • Phoretic on Bark Beetles (Coleoptera: Scolytinae): Global Generalists, Local Specialists?
    ARTHROPOD BIOLOGY Diversity and Host Use of Mites (Acari: Mesostigmata, Oribatida) Phoretic on Bark Beetles (Coleoptera: Scolytinae): Global Generalists, Local Specialists? 1,2,3 1 2 WAYNE KNEE, MARK R. FORBES, AND FRE´ DE´ RIC BEAULIEU Ann. Entomol. Soc. Am. 106(3): 339Ð350 (2013); DOI: http://dx.doi.org/10.1603/AN12092 ABSTRACT Mites (Arachnida: Acari) are one of the most diverse groups of organisms associated with bark beetles (Curculionidae: Scolytinae), but their taxonomy and ecology are poorly understood, including in Canada. Here we address this by describing the diversity, species composition, and host associations of mesostigmatic and oribatid mites collected from scolytines across four sites in eastern Ontario, Canada, in 2008 and 2009. Using Lindgren funnel traps baited with ␣-pinene, ethanol lures, or Ips pini (Say) pheromone lures, a total of 5,635 bark beetles (30 species) were collected, and 16.4% of these beetles had at least one mite. From these beetles, a total of 2,424 mites representing 33 species from seven families were collected. The majority of mite species had a narrow host range from one (33.3%) or two (36.4%) host species, and fewer species had a host range of three or more hosts (30.3%). This study represents the Þrst broad investigation of the acarofauna of scolytines in Canada, and we expand upon the known (worldwide) host records of described mite species by 19%, and uncover 12 new species. Half (7) of the 14 most common mites collected in this study showed a marked preference for a single host species, which contradicts the hypothesis that nonparasitic mites are typically not host speciÞc, at least locally.
