Bozsik, A. (2011). Occurrence of the tulip tree aphid (Illinoia liriodendri Monell, 1879 (Hemiptera: Aphididae) in Hungary. Acta Agraria Debreceniensis, (43), 93–96. https://doi.org/10.34101/actaagrar/43/2644
The genus Illinoia is found primarily in North America. Illinoia liriodendri (Monell, 1879), the tulip tree aphid, has been observed and caught for the first time in Hungary. Nymphs, apterous and alate viviparous females in colonies of I. liriodendri were found on a tulip tree, Liriodendron tulipifera L. (Magnoliaceae), in Debrecen, Hungary. Tulip tree aphid feeds on the underside of tulip tree leaves. The consequences of this are honeydew and associated black sooty mould causing a mess – in countries where the tulip tree is native or abundant - for walking people and parked cars. A short report is presented here on the discovery in Hungary and characteristics of this aphid.
