Got leafrollers? Are you interested in alternatives for their management? Ever wondered how your farm landscape may play a positive role in pest management? If so, this farm walk is for you. The Farmscaping for Beneficials (FSB) Project of the Integrated Plant Protection Center (IPPC) at Oregon State University (OSU), and Jim Hinsvark of Hinsvark Berry Farm invite local caneberry growers to take a break with us for an afternoon of discussion and discovery with parasitoids, beneficial habitat and caneberry leafrollers Tuesday, June 16th from 2-5 at Hinsvark Berry Farm.

The walk will feature Hinsvark Berry Farm, a 35 acre, certified organic berry farm. Jim grew up on the farm and began growing organic berries about 20 years ago. Now he sells his machine-harvested berries in the fresh, frozen and juice markets. The very flat, almost square fields surrounded by nurseries and native plantings are located south east of Woodburn. Researchers from OSU will present information from a two-year study on parasitoids and pesticide use that was conducted in caneberry fields throughout the Willamette Valley and Northern Washington.

We will also be taking a detailed, hands-on, look into the identification, biology, and ecology, of native parasitoids that attack leafrollers and the on-farm habitat that could support them. You will leave with a heightened appreciation for beneficial insects, their role in pest management and the opportunities that exist to enhance habitats for them on your own farm. Don’t miss this unique opportunity to follow a veteran berry grower and bugscapers as we attempt to understand and observe how the complex web of biodiversity and crop production interact right before our eyes!

Come witness first hand, the deadly world of parasitic wasps as they relentlessly pursue their prey against countless obstacles while we probe such riveting questions as, “Do pesticides harm these?, “Why is this wasp called a parasitoid?”, and “Hey, why isn’t this beneficial insect around when I need it the most?”.

This is a free BYOB (bring your own bug) event so if some insect has been bugging you this summer and you don’t know what it is pop it in a jar and bring it along. Participants are also invited to bring a dish to share for the end of-the-walk potluck.

Registration Required

The farm walks are sponsored by OSU’s, Farmscaping for Beneficials Project at IPPC to support grower-led activities that build knowledge and implementation of conservation biological control (CBC) on local farms. Conservation biological control can be defined as methods used on and around farms to restore and enhance beneficial organism populations that may limit pest populations. Such methods may include insectary plantings and field margins, beetle banks and hedgerows.
