First report of Illinoia liriodendri in the Czech Republic
The NPPO of the Czech Republic recently informed the EPPO Secretariat of the first finding of Illinoia liriodendri (Homoptera: Aphididae – tulip tree aphid) on its territory. I. liriodendri was found during a survey carried out in June 2015 in a public green area located in the municipality of Opava (Moravian-Silesian region). Aphids were found on 1 tulip tree (Liriodendron tulipifera). Lower leaves were covered with aphid colonies and typical leaf deformation was observed. Because of the low economic importance of I. liriodendri and low prevalence of L. tulipifera in the Czech Republic, no official phytosanitary measures were taken.
The pest status of Illinoia liriodendri in the Czech Republic is officially declared as: Present; only in one locality.
EPPO note: I. liriodendri is a North American species, feeding on L. tulipifera, which has been introduced into Europe where it is spreading. It has also been reported in Asia (Japan and the Republic of Korea). A geographical distribution can be found in the EPPO Global Database (https://gd.eppo.int/taxon/MACSLR/distribution).
