Details on glasshouse quarantine pests in EPPO countries
During the EPPO Conference on 'Introduced glasshouse pests: problems and solutions' (Pruhonice, CZ, 1998-10-13/15), the situation of the following glasshouse quarantine pests was presented by 12 EPPO countries (Czechia, Denmark, France, Germany, Hungary, Lithuania, Netherlands, Norway, Poland, Slovakia, Sweden, United Kingdom). Papers presented at this Conference will be published in the EPPO Bulletin.
Bemisia tabaci (EPPO A2 quarantine pest): Absent from Lithuania and Slovakia. Denmark, Sweden and United Kingdom are EU protected zones. Every year outbreaks are found but are eradicated each time. It is established in France and the Netherlands. In the following countries, it is considered as locally present, and in most cases problems are essentially seen on Euphorbia pulcherrima and Hibiscus. In Czechia, where it occurs since 1987, small numbers of outbreaks are found and are subject to eradication methods. In Germany, it is often found together with Trialeurodes vaporariorum, measures are taken for plants sent to EU protected zones. In Hungary, it occurs occasionally on ornamentals but has never been seen on vegetables. It has been locally present in Norway since 1987, and can cause problems on E. pulcherrima. In Poland, it is subject to internal quarantine measures.
Frankliniella occidentalis (EPPO A2 quarantine pest): Absent from Lithuania. It is now established in Czechia, Denmark (efforts are made to exclude it from plants for planting), France, Germany, Hungary, Netherlands, Norway, Slovakia, Sweden (widespread on ornamentals but rare on vegetables), United Kingdom. In Poland, it occurs locally, at low levels and is subject to internal quarantine measures.
Helicoverpa armigera (EPPO A2 quarantine pest): It is absent from Lithuania, Slovakia and Sweden. In Czechia and Hungary, the pest can occasionally migrate but always dies out in winter. In Czechia, it was found in Moravia in 1994 and eradicated. In Hungary, it was found in some years, but has not been seen during the last two years. In the Netherlands, outbreaks have occasionally been reported in relation to imports but have always been eradicated.
Liriomyza bryoniae (EU Annexes): Absent from Norway, Slovakia, Sweden. It occurs in Czechia, Denmark, Hungary, Lithuania, Netherlands, Poland, United Kingdom (south of England). In most cases, it is considered as a minor pest of tomatoes.
Liriomyza huidobrensis (EPPO A2 quarantine pest): Absent from Hungary, Lithuania, Norway (found in 1995, but confirmed absent in 1996), Slovakia, Sweden (one outbreak reported in 1998 on imported material but eradicated). Reported as locally present in the following countries. In Czechia, it was first found in 1993 and is still subject to containment and suppression measures. In Denmark, occasional outbreaks are reported, and plants concerned are destroyed or treated. In Germany, it occurs locally and temporarily. In Poland, it causes occasional outbreaks and is subject to internal quarantine measures. In United Kingdom, it has occurred sporadically since 1989. Eradication measures were applied until 1991. However, phytosanitary measures are still applied for plants for planting. The pest is now established in France and the Netherlands (where it is reported as the most frequent leaf miner).
Liriomyza trifolii (EPPO A2 quarantine pest):
Absent from Denmark, Lithuania, Norway, Slovakia. It has been found and subsequently eradicated from Czechia and Hungary. It is no longer seen in Poland and Sweden. It is now rarely seen in Germany and United Kingdom. It is present but less frequent in the Netherlands. In many cases, L. trifolii has been displaced by L. huidobrensis.
Tomato spotted wilt tospovirus (EPPO A2 quarantine pest): Absent from Lithuania. Established in Czechia, Hungary (it poses problems both indoor and outdoor), Netherlands, United Kingdom. Sweden is an EU protected zone (the virus was found in 1996 but was not seen again). Denmark was an EU protected zone until 1998-07, but efforts are still being made to exclude it from plants for planting (as well as impatiens necrotic spot tospovirus). The virus occurs in Norway but is under eradication. In Slovakia, it has been reported in a few locations since 1993, infected plants are destroyed.
