Abstract [en]

The major sex pheromone compound of the spotted tentiform leafminer, Phyllonorycter blancardella (F.) (Lepidoptera: Gracillariidae), from Ontario, Canada, was identified as (10E)-dodecen-1-yl acetate (E10-12:Ac) using chemical analysis and field trapping experiments. The minor compounds (10E)-dodecen-1-ol (E10-12:OH) (4.6%), dodecan-1-ol (12:OH) (2.3%), and (10Z)-dodecen-1-yl acetate (Z10-12:Ac) 1.6% were also identified. The dienic acetate (4E,10E)-dodecadien-1-yl acetate (E4,E10-12:Ac), a compound reported to be attractive to P. blancardella, was not found in the glands of this population. A two-component blend of the major and one of each the three minor compounds, in ratios similar to those found in the sex pheromone gland, did not increase the attractiveness of traps baited with synthetic pheromone. The minor compounds E10-12:OH and 12:OH were not attractive to P. blancardella when tested individually. Z10-12:Ac was attractive to P. blancardella, although traps baited with this compound captured only 2% of the moths that were captured in traps baited with the main compound. A four-component blend of the major and each of the three minor compounds (100 : 1 : 1 : 1) was not more attractive than the major compound alone. The related species Phyllonorycter mespilella was captured in traps baited with E10-12:Ac.
