The NPPO of Lithuania has recently sent to the EPPO Secretariat the present situation of the following quarantine pests.
Anarsia lineatella (recently deleted from the EPPO lists) was found using pheromone traps in 2 orchards. All infested branches were pruned and burned. No planting material was allowed to move from these orchards.
Clavibacter michiganensis subsp. sepedonicus (EPPO A2 quarantine pest): as already reported in EPPO RS 99/115, ring rot occurs in Lithuania. The National survey has shown the occurrence of 7 foci. The following 8 potato cultivars grown in Lithuania were found infected: Nida, Karolin, Pemperna, Sineglazka, Rossella, Mirta, Helena, Sante (including seed potatoes and ware potatoes). All infected potatoes were used for animal feed, industrial processing or consumption.
Frankliniella occidentalis (EPPO A2 quarantine pest) was found in ornamental glasshouses at 3 production sites. At one site producing annual plants, all plants were destroyed and glasshouses were left to freeze during 3 months. At the other two sites, chemical control was applied. Previously, this pest was considered as absent from Lithuania.
Liriomyza bryoniae (EU Annexes) was trapped in glasshouses at 5 production sites. Infected plants have been destroyed and chemical treatments applied.
