Natural Enemies in Action

Here's a look at just a few of the natural enemies that can be found in Pacific Northwest tree fruit orchards.

NE Rearing: The green lacewing, Chrysoperla johnsoni

Dr. Kaushalya Amarasekare demonstrates how to rear the green lacewing Chyrosperla johnsoni in a laboratory setting at the OSU Mid-Columbia Agricultural Research and Extension Center, Hood River, OR, USA.

Pesticide Effects: Testing sublethal effects of peticides on predatory mites

Dr. Elizabeth Beers defines and explains the need for mesocosm studies to determine the sublethal effects of pesticides on natural enemies. This video then demonstrates how to set up such an analysis for the Western predatory mite, Galandromus occidentals in the laboratory located at the Washington State University Tree Fruit Research and Extension Center in Wenatchee, WA, USA.

How to: Making HIPV lures, trap assembly and field placement

Herbivore Induced Plant Volatiles, or HIPV for short, are useful natural enemy attractants. We demonstrate how to make HIPV lures, assemple various traps and place them in an orchard to monitor natural enemies.

To learn more about our work with HIPV lures, check out the Objective 3 results: 2009 2010 2011 2012 (click on the Obj. 3 tab).

Perspectives: Dr. Vince Jones' viewpoint on the future of orchard IPM

Project Director Dr. Vince Jones was invited to give his unscripted opinion about the future of IPM for orchard crops. This is part of a Viewpoints video series produced by UC Extension Specialist Dr. Marshall Johnson at the UCR Parlier, Experiment Station. Dr. Jones is a Professor of Entomology for Washington State University at the Tree Fruit Research and Extension Center in Wenatchee, WA. and has over 35 years experisnce in orchard IPM and biological control.

Perspectives: Cooperators on monitoring green lacewing adults with HIPV traps

A handfull of select tree fruit industry pest managers volunteered to help us evaluate the usefulness of HIPV lure traps for monitoring green lacewing adults in their orchards. At the end of the season we asked them to comment about various aspects of trap use. Their comments and insightswere invaluable to refine and improve the trap for a repeat trail the following year.

Perspectives: Mike Robinson on enhancing biocontrol

We interviewed several crop consultants about their experiences with enhancing biocontrol in the orchards they manage. In this video, Mike Robinson shares his perspectives. Mike has over 30 years experience with orchard IPM, with the last 10 or more years using biocontrol as a major component. His insights should be helpful to anyone using or thinking of using biocontrol as part of their management practices.


How to: Attaching a moth to a flight mill for behavioral studies

Sublethal pesticide effects on insects can manifest in many ways. One subtle effect can be on flying behavior: how long/far they fly, how often, and periodicity of flight. The flight mill is one way to measure the effected flight behaviors. Graduate Student Teah Smith demonstrates how to attach a moth to a flight mill used in such experiments. For more information visit the Flight Mill page. The original design and development of the Flight Mill was by Dr. Steven Naranjo of the USDA-ARS Arid-Land Agricultural Research Center at Maricopa, AZ USA.
