Develop and test prediction models for the management of blueberry flea beetle by means of managing the larvae based on the adult capture of the beetle the previous year. After collections from both years (larvae and adult beetle) proceed and investigate the relationship between the flea beetle populations and crop defoliation as well as the population of the adult flea beetles and the flora bud production. To be able to refine treatment thresholds for flea beetle larvae and adults and to assess the possibility of being able to control both flea beetle and fruit fly with one insecticide application in the sprout year.
Develop a prediction model for larvae based on adult populations in the sprout year. Refine the treatment threshold based on larvae stage. Develop a treatment threshold based on adult population the sprout year. Examine the potential of treating both flea beetle and blueberry fruit fly with the same insecticide application.
