Abstract


Summary.- Six isolates of recently detected Nacobbus aberrans populations from Argentina were raised under glasshouse conditions. Different representative stages of the nematode’s life cycle were characterized morphometrically. Significant differences were observed between isolates for most of the characters of the different stages evaluated. Those characters that made the greatest contribution to discrimination between isolates were selected. A cluster analysis revealed a clear grouping of nematodes raised on the same host when considering second-stage juveniles, males, and immature females.
These results would indicate that the host had a particular influence on morphometric character expression.
