Abstract

The pterin age-grading method was applied to natural populations of stable flies sampled for 3 years from diverse locations in Minnesota and Iowa. Significant differences were detected among years in mean degree-day ages per fly. Fly ages, in degree-day units, were exponentially distributed. A two-parameter Weibull distribution closely fit the fly survival distributions. Mean expectations of life did not differ significantly between males and females and were estimated to be 86.6 degree-days above a 6.5 °C threshold. Conventional age-grading techniques based on ovarian morphology applied to Iowa females showed that large fractions of the populations experienced delays in vitellogenesis. The reproductive rate, in terms of lifetime ovipositions, was less than the maximum sustainable rate suggested by ambient temperatures.

Résumé

La méthode de détermination de l’âge au moyen de ptérine a été utilisée chez des populations naturelles de mouches des étables de diverses localités du Minnesota et de l’Iowa échantillonnées durant 3 ans. D’une année l’autre, il y avait des différences significatives de l’âge moyen en degrés-jours. L’âge des mouches, en unités de degrés-jours, suivait une distribution exponentielle. Une distribution de Weibull à deux paramètres illustre bien la survie des mouches. L’espérance de vie ne diffère pas significativement chez les mâles et chez les femelles et elle a été estimée à 86,6 degrés-jours au-dessus du seuil de 6,5 °C. Des techniques classiques de détermination de l’âge basées sur la morphologie des ovaires ont été utilisées sur les femelles de l’Iowa et les résultats démontrent que d’importantes proportions de la population ont subi des retards dans la vitellogénèes. Le taux de reproduction, évalué d’après le nombre de pontes au cours de la vie, s’est avéré inférieur au taux maximum théorique estimé d’après les températures ambiantes.
