The general objective of this project is to investigate biological control of the tarnished plant bug in New York strawberries by the introduced parasitoid wasp Peristenus digoneutis. The first project goal for 1999 was to evaluate the impact of companion plantings of alfalfa on parasitism rates in nearby strawberries. Sample have been collected from this experiment, but they have not been analyzed yet, and no results are available. The second project goal was to evaluate P. digoneutis activity in New York strawberries (and other plant habitats) near the edge of the known P. digoneutis range and beyond.
