Summary: The objectives of this project were: 2001 ● Document and describe mating behaviors of the western cherry fruit fly in the laboratory. ● Determine effects of age on mating success and fecundity. ● Document mating behaviors of flies in the field. 2002 ● Demonstrate the presence of a mating pheromone in the fly using laboratory wind tunnel and field bioassays. ● Compare the ability of laboratory- and field-collected males to attract females. ● Characterize the chemicals responsible for attraction of females to males. 2003 ● Continue to establish presence of pheromones or odors involved in mating behavior. ● Determine visual factors involved in successful mating by flies. ● Determine effect of nutrition on mating success. ● Effects of age on mating and egg hatch success in the laboratory and field.
