    Notes: Abstract (E4,E10)-dodecadienyl acetate (E4,E10-12∶OAc) is a newly discovered sex pheromone component of the tentiform leafminer,Phyllonorycter mespilella (Hübner). In apple orchards, traps baited with 1Μg ofE4,E1012∶OAc attractedP. mespilella in British Columbia andP. blancardella (F.) in Massachusetts and Nova Scotia. The compound was identified inP. mespilella by gas chromatographic-electroantennographic analysis (GC-EAD) of pheromone gland extracts, retention index calculations, EAD profiles toE3 toE10 dodecenyl acetates, and synthesis of candidate pheromone components. Even thoughE4,E10-12∶OAc was not detected in gland extracts by GC-mass spectroscopy, several factors indicate that it is female-produced. Antennal responses to gland extracts coincided with authenticE4,E10-12∶OAc on four GC columns with different retention characteristics.E4,E10-12∶OAc andE10-12∶OAc, a known female-produced pheromone component, elicited equally strong EAD responses. In field tests,E4,E10-12∶OAc was two to four times more attractive thanE10-12∶OAc. There was no additive or synergistic effect between the two components.

    Response of male eye-spotted bud moth,Spilonota ocellana (Lepidoptera: Tortricidae), to different pheromone blends in north America and The Netherlands (1994)

    Notes: Abstract Response of male eye-spotted bud moth,Spilonota ocellana (Denis and Schiffermüller), to different ratios of synthetic sex pheromone components, (Z)-8-tetradecenyl acetate (Z8-14:OAc) and (Z)-8-tetradecenyl alcohol (Z8-14:OH), were compared in four North American locations and in one location in The Netherlands. In British Columbia, Nova Scotia, Michigan, and The Netherlands, a 99:1 blend ofZ8-14:OAc andZ8-14:OH captured significantly more maleS. ocellana thanZ8-14:OAc alone or binary blends containing 10–50%Z8-14:OH. In Ontario, where population sizes were low compared to the other four locations, trends in trap catches were similar, and there was no indication that maleS. ocellana responded differently to the tested pheromone blends. A 99:1 blend ofZ8-14:OAc andZ8-14:OH should be most effective in pheromone-based control programs ofS. ocellana in North America and in The Netherlands. Our results confirm earlier studies that a 99:1 blend ofZ8-14:OAc andZ8-14:OH captures significantly more maleS. ocellana thanZ8-14:OAc alone. However, our finding that a 99:1 blend ofZ8-14:OAc andZ8-14:OH is significantly more attractive than binary blends containing 10–50%Z8-14:OH differs from previous findings in Germany and Switzerland.
