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.

The pygmy whitefish (Prosopium coulterii (Eigenmann and Eigenmann, 1892)) is a glacial relict species with a disjunct North American distribution that, apart from its most easterly known location in Lake Superior, is predominantly found in northern and western regions of Canada. Here we report on a new finding of pygmy whitefish from Winnange Lake in northwestern Ontario that extends the range of this species ∼320 km from its most easterly distribution in Lake Superior and almost 1500 km east of the closest previously known western localities. Genetic analyses confirmed that the fish from Winnange Lake were most closely related to the lineage that includes fish from Lake Superior and likely also originated via postglacial dispersal from a refugium in the upper Mississippi – Missouri river system.

Spiroplasma strains from plant and arthropod hosts, and from surfaces of flowers, were classified into three serological groups (designated I, II, and III) based on results from growth-inhibition tests. No significant cross reactions were observed among groups. The groupings were confirmed by ring-interface precipitin and microprecipitin tests, using membrane preparations as test antigens, and by organism-deformation tests. Serogroup I contained three subgroups: subgroup A (Spiroplasma citri strains Maroc R8A2 and C 189), subgroup B (strain AS 576 and closely related strains from honeybee or flowers), and subgroup C (corn stunt spiroplasma strains). Serogroup II contained strains 23-6 and 27-31 isolated from flowers of the tulip tree (Liriodendron tulipifera L.) growing in Maryland. Serogroup III contained strains SR 3 and SR 9 isolated from flowers of the tulip tree growing in Connecticut. The subgroups of serogroup I were based on organism deformation, microprecipitin, and ring-interface precipitin tests. The data are consistent with the hypothesis that the three serogroups represent no less than three distinct spiroplasma species.
