Abstract: | "(E4,E10)-dodecadienyl acetate (E4,E10-12ratioOAc) is a newly discovered sex pheromone component of the tentiform leafminer,Phyllonorycter mespilella (Hubner). In apple orchards, traps baited with 1Mug ofE4,E1012ratioOAc 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,E10-12ratioOAc 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,E10-12ratioOAc on four GC columns with different retention characteristics.E4,E10-12ratioOAc andE10-12ratioOAc, a known female-produced pheromone component, elicited equally strong EAD responses. In field tests,E4,E10-12ratioOAc was two to four times more attractive thanE10-12ratioOAc. There was no additive or synergistic effect between the two components" |
