Abstract

The rate of hatch of overwintered eggs of the strawberry aphid, Chaetosiphon fragaefolii (Cockerell), at five temperatures in controlled environment chambers was used to determine the thermal threshold of development. Samples of eggs were taken from two field locations several times before hatch. These samples were subdivided and placed into two or three different constant temperature chambers. The day-degree requirements for hatching from the time of collection were estimated. These estimates corresponded to the number of day-degrees actually accumulated in the field between the time of egg collection and the time of hatching.

This method of simulating the effect of temperature on egg development was an accurate method of predicting the time of hatch in the field at least 3 weeks prior to the observed time.

Résumé

Le taux d'éclosion des oeufs hivernants du puceron du fraisier Chaetosiphon fragaefolii (Cockerell) mesuré à 5 températures dans des chambres à ambiance contrôlée a été utilisé afin d'établir le seuil thermique de développement. Des échantillons d'oeufs ont été prélevés à deux sites sur le terrain et à plusieurs reprises avant l'éclosion. Ces échantillons ont été subdivisés et placés dans deux ou trois chambres à température constante. Les degrés-jours requis entre le prélèvement et l'éclosion des oeufs ont été évalués. On a observé que ces estimés correspondent aux degrés-jours accumulés sur le terrain entre la date du prélèvement et l'éclosion.

Cette méthode de simulation de l'effet de la température sur le développement des oeufs s'est avérée précise pour prédire la date d'éclosion sur le terrain au moins trois semaines avant la date observée.
