New data on quarantine pests and pests of the EPPO Alert List
By searching through the literature, the EPPO Secretariat has extracted the following new data concerning quarantine pests and pests included (or formerly included) on the EPPO Alert List, and indicated in bold the situation of the pest concerned using the terms of ISPM no. 8.
- New records
Halyomorpha halys (Hemiptera: Pentatomidae – formerly EPPO Alert List) has recently been reported from Kazakhstan (Zhunisbai et al., 2019). Present, no details.
Ips sexdentatus (EU Annexes) occurs in Kazakhstan (Linch et al.,2019). Present, no details.
Leptoglossus occidentalis (Hemiptera: Coreidae) is reported for the first time from Cyprus. One adult specimen was found in April 2019 in the Paphos forest. This forest is mainly composed of Mediterranean pine species, and located in the Western part of the Troodos Mountains (van der Heyden & Zettel, 2019). Present, few occurrences.
Leptoglossus occidentalis (Hemiptera: Coreidae) is reported for the first time from Argentina. The first specimens were found in December 2017 in El Bolson (Rio Negro province). Other detections were then made in other localities (Bariloche and Dina Huapi) (Kun & Masciocchi, 2019). Present, few occurrences.
Phoracantha recurva (Coleoptera: Cerambycidae – formerly EPPO Alert List) is reported for the first time from Mexico (Cortés-Aguilar et al., 2019). Present, no details.
- Detailed records
In Germany, Synchytrium endobioticum (EPPO A2 List) was found in ware potatoes in Niedersachsen during a phytosanitary inspection. The source of the infestation is not known so far but eradication measures have been taken.
The pest status of Synchytrium endobioticum in Germany is officially declared as: Present, few occurrences, at low prevalence.
In Italy, Xylosandrus crassiusculus (Coleoptera: Scolytidae - EPPO Alert List) was first found in Toscana (EPPO RS 2009/054) and then in other regions (Liguria, Veneto). It was first recorded in Cuneo Province (Piemonte) in April 2018 in recently planted Japanese hybrids of chestnut trees (Dutto et al., 2018).
- Eradication
During research studies carried out in Spain, Tomato chlorotic dwarf viroid (Pospiviroid, TCDVd) was detected on Solanum melongena (EPPO RS 2019/154). The NPPO of Spain recently informed the EPPO Secretariat that this finding was made only in the framework of an experiment conducted at the Universitat Politècnica de València. All infested plants, as well as all other plants present in the greenhouse were destroyed, and the facilities were disinfected. Surveys were carried out in the adjacent greenhouses and in all outdoors plots of the university campus. Seed lots which had been used and seed beds were tested for TCDVd and all results were negative. Therefore, it is considered that TCDVd has been eradicated.
The pest status of Tomato chlorotic dwarf viroid in Spain is officially declared as: Absent, pest eradicated.
- Host plants
Cordia myxa (Boraginaceae) is first recorded as a host plant of Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae – EPPO A1 List - vector of ‘Candidatus Liberibacter asiaticus’) in the southern region of the state of Punjab, Pakistan.
