Abstract
The oriental aphid Schizaphis piricola (Matsumura) is recorded for the first time in Europe, on the ornamental pear tree Pyrus calleryana in landscaped areas in Madrid (Spain). Data on the morphology of the forms on primary host (apterous and alate fundatrigeniae and fundatrices), and their biology and distribution are given. The keys for identifying species of Schizaphis (Schizaphis) in the Iberian Peninsula are updated. Two species of aphids are also recorded for the first time on Pyrus calleryana: Schizaphis piricola and Aphis pomi.
Highlights
The genus Schizaphis Börner contains approximately 36 Palearctic species and 6 Nearctic ones
Most of the species in the genus are monoecious on species of Poaceae, Juncaceae and Cyperaceae but a few mainly oriental species, are dioecious with species of Pyrus as the primary host, where they lay their cold-resistant eggs (Blackman and Eastop 2006)
Eight of them were recorded in the Iberian Peninsula (Pérez Hidalgo and Mier Durante 2005; Blackman and Eastop 2006): S. graminum (Rondani), S. longicaudata Hille Ris Lambers, S. pyri Shaposhnikov, S. rotundiventris (Signoret), S. (Euschizaphis) palustris (Theobald), S. (Paraschizaphis) caricis (Schouteden), S. (Paraschizaphis) rosazevedoi (Ilharco) and S. (Paraschizaphis) scirpi (Passerini)
