1) Volatile recapture methodology will be used to quantify the emission rate of pear ester from the MEC formulation aged on apple foliage over a 35 d period. 2) Larval observations will be conducted using several cultivars of apple, pear, and walnut foliage treated with the MEC formulation. 3) Field bioassays will be conducted with a select group of new insecticides registered for codling moth to examine whether the pear ester MEC can enhance insecticidal activity. These studies will focus on the apple cultivar Granny Smith. 4) A piezoelectric sprayer will be used to examine the subtle interactions of pear ester and sex pheromone on adult orientation behaviors. 5) Moth antennal responses following pre-exposure to sex pheromone and pear ester blends will be examined using an EAG and flight tunnel tests will examine moth orientation behavior following exposure. 6) Dispensers loaded with various blends of sex pheromone and pear ester will be evaluated in replicated field plots using virgin female-baited sticky traps.
