Incursions reported by Finland
The NPPO of Finland recently informed the EPPO Secretariat of the following incursions found recently on ornamental, fruit and vegetable crops.
Impatiens necrotic spot tospovirus (INSV – EPPO A2 list) was found in August 2003 in cut flowers of Chrysanthemum, and in September in pot plants of Kalanchoe blossfeldiana and Schlumbergera. In both cases, the pathways of introduction of INSV are unknown. Eradication measures were immediately taken. Earlier incursions of INSV were reported in 2001, 2002 and 2003 (see EPPO RS 2001/201, 2002/169, 2003/073).
The situation of Impatiens necrotic spot tospovirus in Finland can be described as follows: Transient, actionable. Incursions are occasionally reported under glasshouse, under eradication.
Glomerella acutata (anamorph Colletotrichum acutatum - EU Annexes) was found in July 2003 on strawberry plants (Fragaria ananassa cv. Polka) growing in the field. The source of infestation is thought to be planting material imported from the Netherlands. Strawberry plants were destroyed and phytosanitary measures applied. Earlier incursions were reported in 2000 and 2002 (EPPO RS 2001/199, 2002/173).

Liriomyza huidobrensis (EPPO A2 list) was found in September 2003 in pot plants of Gerbera at one nursery. Eradication measures were immediately taken, all infested plants were destroyed and appropriate treatments were made. Earlier incursions of this pest were reported in 1992, 1997 and 2002 (see EPPO RS 93/014, 97/181, 2003/021).

Leptinotarsa decemlineata (Coloptera: Chrysomelidae – EPPO A2 list) was found in July/September 2003 in one potato-producing farm and in five home gardens. Earlier incursions of L. decemlineata were reported in 2001 and 2002 (see EPPO RS 2001/201 and 2002/165). Some of the fields where L. decemlineata was found in 2003 were in the same region as the findings in 2002. The farms and home gardens where L. decemlineata was found in 2002 were inspected in 2003 and found free from the pest. Concerning the 2002 incursion, it was suggested that the beetle was carried by a heavy storm from the eastern part of Estonia but, for the 2003 incursion, the pathway of introduction remains unknown. Eradication measures have been taken.
The situation of Leptinotarsa decemlineata in Finland can be described as follows: Transient, actionable. Incursions are occasionally reported in potato fields or gardens, under eradication.
Tomato spotted wilt tospovirus (TSWV – EPPO A2 list) was found in September 2003 in plants of tomato (Lycopersicon esculentum) and chrysanthemum cut flowers at one nursery. The pathway of introduction of TSWV is unknown. Eradication measures were immediately taken. Earlier incursions of TSWV were reported in 1989, 1992 and 2001 (see EPPO RS 500/16, 2001/086, 2001/127, 2001/201).
