Frankliniella occidentalis on glasshouse and outdoor crops in Hungary
F. occidentalis has occurred on glasshouse crops in Hungary (first record by Jenser, G. & Tusnadi, Cs. K., Növényvédelem, 25 (9), 389-393, 1989). In a survey by G. Jenser (Anzeiger für Schädlinqskrude Pflanzenschutz Umweltschutz 63., 114 -116 (1990)) of wild and cultivated plants around infested glasshouses, 23 out of 34 species showed f lower infestation. It is inferred that such infestation can -contribute to spread of the pest during the growing season, but it is not yet known whether the pest can overwinter in the field. Some of the infested species are hosts of tomato spotted wilt virus, vectored by F. occidentalis.
This is confirmed by the Plant Health and Soil Conservation Department (Budapest) which reports that in 1989. F. occidentalis was found at 4 localities, on gerbera and saintpaulia under glass, and on rose. Rapid measures were taken to eliminate these infestations, and it is intended to put the pest on the Hungarian quarantine list.
