Pear moth – Cydia pyrivora is a narrow oligophage, whose larvae feed on the pith and pulp of fruit pears. In the region the species is connected here with warm biotopes on the Volga’s slopes and inhabits garden plots and abandoned gardens with pear trees. The areal extent in the north-east of the European part of Russia is considered for the pear moth Cydia pyrivora over a 60-year period. Over the past decade there has been quite a rapid expansion of the species to the north on the floodplain of the Volga river up to the Centre of the Ulyanovsk Province.
