Differences in the relationship between sensory adaptation of antennae and concentration of aerial pheromone in the oriental fruit moth and obliquebanded leafroller (Lepidoptera: Tortricidae): implications for the role of adaptation in sex pheromone-mediated mating disruption of these species.


The antennae of Grapholita molesta (Busck) are more susceptible to sex pheromone-induced sensory adaptation than the antennae of Choristoneura rosaceana (Harris). Adaptation is detectable in G. molesta at 1/1,000th the aerial concentration of pheromone (i.e., 5.0 x 10(-7) ng Z8-12:OAc/ml air) that is required to induce detectable adaptation in C. rosaceana… (More)
