Codling moth (Cydia pomonella), is a common pest in British Columbian apple orchards. The C. pomonella larvae are a primary cause of insect fruit damage (Landolt et al., 1999), as they feed on the apple throughout early development. In order to help the profit margins of apple orchards, effective pest control that is biodegradable, easy to apply and that does not leave dangerous resins on the fruit is needed. C. pomonella produce an aggregation pheromone that attracts both male and female larvae equally to pupation sites (Jumean et al., 2004). The pheromone’s effect has been replicated with application of a synthetic blend to C. pomonella larvae (Jumean et al., 2007). The use of pheromone-impregnated tree bands have been used successfully in pest control management of C. pomonella. However, the cost benefit of this type of management is outweighed by the labor costs associated with placement and removal of the tree bands. rn In this experiment, I plan to investigate the possible use of a sprayable foam as a delivery vehicle for the synthetic blend. Once attracted to the foam, the C. pomonella larvae will be killed by the foam. An olfactometer experiment will be conducted by placing a culture of fifth-instar C. pomonella larvae inside a plexiglass box. At opposing corners of the box, two foam deposits will be made. One will be impregnated with the synthetic blend while the other will not be impregnated with anything. After a day of exposure, both deposits will be inspected for the presence of C. pomonella larvae. If the impregnated deposit has a statistically greater number of larvae than the control deposit, we will have proof of principle that the synthetic blend foam will be an effective pest management tool for application on fruit trees. rnrnWorks CitedrnrnJumean, Z., Judd, G., & Gries, G.
