Interpretive Summary:

Technical Abstract: This talk reviews the mating disruption mechanism and work that we have done in the Steffan lab summers 2012-2014. In 2016 we mechanized the deployment of mating disruption with the use of unmanned aerial vehicles. We are not continuing this form of mechanization at this time due to challenges with battery life. In 2017, we are mechanizing mating disruption deployment by using boom arms. Degree-day models are important tools for pest managers to hone management timings. We have been working on the creation of the cranberry fruitworm degree-day model. In 2015, we determined the developmental temperature thresholds for growth. In 2016, we correlated cranberry fruitworm degree-days with flight initiation and peak flight. We will be continuing this work to determine the time to oviposition and larval emergence.
