Frequent use of insecticides is generally necessary for effectively managing spotted wing drosophila (Drosophila suzukii, SWD) for susceptible berry crops. Hence, there is a great need for alternative control methods. Our group has been particularly interested in identifying chemicals that are repellent or deterrent to SWD and developing their use, in combination with attractants, into a push-pull management tool. In this talk we will report on experimental results from the laboratory, greenhouse and field documenting significant reductions in infestation by SWD of highly susceptible raspberry fruit in response to different candidate repellent compounds.
