The first record of tulip tree aphid, Illinoia liriodendri (Hemiptera: Aphididae), from Slovakia – short communication

摘要

The tulip tree aphid, Illinoia liriodendri, is reported in Slovakia for the first time. Colonies of I. liriodendri were found on tulip trees, Liriodendron tulipifera, in two locations of south-western Slovakia in 2014 and 2015. Colonies of nymphs and viviparous females fed on the underside of leaves with no significant symptoms of damage to tulip trees. In this short study, the first report of the aphid from Slovakia is presented and original illustrations with results of morphometric analysis of alate viviparous females are provided.
