The Pacific Northwest is the nation’s largest producer of small fruit and cherries, with an estimated combined value of over $922 million (all caneberries: $133 million, blueberries: $192 million, strawberries: $25 million, cherries: $572 million, OR and WA combined, 2012 NASS figures).

The project will train and mentor undergraduate students in monitoring, recording, processing and extending data/information to stakeholders. It will expand monitoring for SWD and other pests and provide area-wide data, commentaries, and iPiPE- supported informational releases to inform extension, researchers, agricultural consultants, and especially growers with up-to-date knowledge concerning current pest levels and risks to fruit crops. Finally it will allow the data to be shared freely and integrated for decision-support, further improvement and validation of still in-development visualization mapping tools and models.

A major disruption of IPM programs began to occur in these major commodities when the spotted wing Drosophila (SWD) arrived in late 2009. Since then, damage and costs associated with managing this new invasive along with excessive use of pesticides have spiraled to a nearly complete collapse of IPM in these production systems. Many growers spray 5- 10 applications to produce a marketable product, when none were used before the arrival of this pest.  Treatment and damage costs, secondary pest outbreaks, and pesticide resistance are all major concerns that have not been adequately addressed. In addition, more recently, the brown marmorated stink bug (BMSB) has emerged as a threat to a variety of fruits, vegetables, and nuts in the PNW. First major crop injury reports were observed in 2014 and 2015, and growers are concerned that this invasive could emerge as an equally intractable pest problem.
