Abstract

The balsam woolly aphid, Adelges piceae, has a complex distribution in the crown of trees; The sample universe and sample units are defined, and methods of detecting, monitoring, and measuring population levels at stated levels of confidence, accuracy, and assurance are described. Suggestions are given for sampling aphids on the stems of trees.

Résumé

Le Puceron lanigère du Sapin, Adelges piceae, a une distribution complexe dans le houppier. L’univers et l’unité d’échantillonnage sont définis; des méthodes de détection, de contrôle et d’évaluation des niveaux de population à des seuils donnés de confiance, de précision et d’assurance sont décrites. Des suggestions sont faites pour l’échantillonnage des pucerons sur la tige des arbes.
