Assessing and Augmenting Biological Control of Tarnished Plant Bug in New York Strawberries 1998

Project Leaders: Mike Hoffman, Kelley Tilmon

Objective:

Evaluate Peristenus digoneutis and other parasitoid activity in established New York strawberries, including day-neutral varieties.

Results:

Tarnished plant bugs were collected from day-neutral and June strawberries on conventional and organic farms in seven counties. Parasitism rates ranged from 4% to 33% and included both the introduced parasitoid wasp P. digoneutis and the native parasitoid wasp P. pallipes. These data show that both species of Peristenus are locating and helping to suppress tarnished plant bug nymphs in strawberries
