Abstract
Decline of allozyme variability in 7 laboratory populations ofAphidius ervi Haliday demonstrates that the effective population size is approximately one half the number of individuals used to renew the cultures each generation. Unequal reproductive contribution by individual females to subsequent generations is the most likely cause for this phenomenon.
Résumé
La diminution de la variabilité des allozymes dans 7 populations de laboratoire deAphidius ervi Haliday montre que l'importance des effectifs des populations correspond approximativement à la moitié du nombre d'individus utilisés pour renouveler l'élevage à chaque génération. Une participation inégale à la reproduction des individus femelles aux générations successives est la cause la plus probable de ce phénomène.
