This work was partially financed by grants from the Hungarian Ministry of Education (OM NKFP 4/008 and NKFP 4/012/2004) to G. Szöcs. W.F. gratefully acknowledges financial support by the Fonds der Chemischen Industrie. We thank R. Duncan (Natural Resources Canada, Canadian Forest Service, Pacific Forestry Centre) for showing us locations where Cameraria infestations occurred and for his preliminary determinations of Cameraria, and we thank P. Opler (now living in Colorado, United States of America) for verifying the determinations. We also thank N. Conder for redrawing the figures and J. Jell, A. Fritz, M. Complin, K. Monge, and M. Ibaraki, who checked the baited traps and exchanged the Tangle-Trap coated inserts in the sticky traps.

N2 - Field trapping trials showed that Cameraria gaultheriella Walsingham and C. lobatiella Opler and Davis (Lepidoptera: Gracillariidae) were attracted in significant numbers in British Columbia, Canada, to sticky traps baited with 10 μg of (E,Z)-8,10-tetradecadienal (E8Z10-14Ald), the sex pheromone of the European horse chestnut leafminer, C. ohridella Deschka and Dimic. There was perfect specificity in captures at habitats located only about 8 km apart from each other: C. gaultheriella was captured exclusively at a humid habitat covered by the shrub salal, Gaultheria shallon Pursh (Ericaceae), whereas C. lobatiella was trapped at an arid location with Garry oak trees, Quercus garryana Dougl. (Fagaceae). Seasonal flight patterns of these two Canadian Cameraria species, as monitored by pheromone traps, indicated differences in their respective flight periods. The possibility of additional cryptic components in the respective pheromones of these three Cameraria species attracted to E8Z10-14Ald is discussed.
