Abstract

Adults of Choristoneura fumiferana, C. biennis, and an unidentified species reared from larvae or caught in pheromone traps from British Columbia were used for isozyme analysis to confirm the species identity, and for morphological study to determine the percentage of individuals with spiculate aedeagi. About 82% of C. fumiferana and less than 3% of both C. biennis and C. unidentified species (CPG) have spicules on the left side of their aedeagi. The number of moths that need to be sampled to determine a species is presented, based on the presence or absence of spicules.

Résumé

Des papillons adultes de Choristoneura fumiferana, de C. biennis et d’une espèce indéterminée issus de larves ou capturés dans un piège à phéromones en Colombie-Britannique ont été utilisés dans une analyse des isoenzymes pour confirmer l’identité des espèces, et dans une étude morphologique pour déterminer la proportion des individus à édéage spicule. Environ 82% des papillons de C. fumiferana et moins de 3% de ceux de C. biennis et de l’espèce indéterminée portaient de spicules du côté gauche de leur adéage. Le nombre de papillons devant être échantillonnés pour déterminer une espèce est indiqué, d’après la présence ou l’absence de spicules.
