The article generalizes the results of studying the alimentary connections of chalcidsof
the family Eurytomidae, as a result of which some regularities are established in the
biological specialization of the family. A deep dependence of phytophagous forms on
plants-hosts is detected which determines the ways of development of some groups of
phytophages. For parasitic species two main tendencies of biological specia'ization arc
observed: phylogenetic and morpho-typical specializations.
