Abstract
Detection of the invasive lime leafminer Phyllonorycter isskii in Novosibirsk in 2008–2009 is reported. The pest mines were found on small-leaved lime Tilia cordata and Siberian lime Tilia sibirica , but not on Amur lime T. amurensis , the usual host of the moth. T. cordata carried 2–3 times more mines than T. sibirica . On both hosts, parasitism of matured larvae and pupae did not exceed 7 %. Lack of control by local parasitoids may give the pest an opportunity to increase population density and to spread further in Western Siberia.
