Cranberry Insect Biology and Phenology

Ongoing work: developmental thresholds and DD benchmarks

We are collaborating with the Rodriguez-Saona lab in Rutgers, NJ to establish the species-specific temperature thresholds for Sparganothis fruitworm. With this information we will be able to determine the exact DD accumulations required for each life-stage event. This will allow growers to refine their control strategies to increase the likelihood that the insect is being targeted at the life stage when it is most vulnerable. Our preliminary findings were presented at the 2013 Wisconsin Cranberry School and the 2013 winter American Cranberry Growers Association meeting. Eventually we will repeat this work for CFW.
