title: [The distribution of entomopathogenic nematodes of the families Steinernematidae and Heterorabditidae in Russia and their morphological characteristics].
abstract: The data on a distribution of nematode species of the families Steinernematidae and Heterorabditidae in the northern and southern regions of the Russian Federation are given. Morphological characters of geographic isolates of some nematode species are not different, while their invasive activities in dependence of a temperature are different. Steinernema feltiae occurs in all climate zones, S. carpocapsae is restricted in distribution, nematode species of the family Heterorabditidae were found in southern regions only.
