Using numerical methods, on the basis of ratios between 14 continuous characters, 4 meristic and one qualitative character of six populations of the genus Aphidius: Aphidius ervi/Acyrthosiphon pisum (Ae-Ap), Aphidius ervi/Sitobion avenae (Ae-Sa), Aphidius microlophii/Microlophium carnosum (Am-Mc), Aphidius rhopalosiphi/Metopolophium dirhodum (Ar-Md), Aphidius uzbekistanicus/Sitobion avenae (Au-Sa) and Aphidius eadyi/Acyrthosiphon pisum (Aed-Ap) have been analyzed. The following meristic and qualitative characteristics: numbant- number of antennal segments, numbcost- number of costulae, MPSF1-number of multiporous plate sensilla on the first flagellar segment, MPSF2- number of multiporous plate sensilla on the second flagellar segment and carpet- dorsal sculpturing of the petiole (the degree of prominence of carinae on the dorsal side of petiolus) were used. The states of these characters were coded for correspondence analysis. Descriptive statistics was calculated for each characters (mean, SE, SD, min., max.).
