Purpose. The Crop Pest Losses and Impact Assessment Working Group was established in 2003 to facilitate the collection of
world data on insect losses in key crops in the low deserts of Arizona and Imperial Valley California. We currently collect data on cotton, head
lettuce, watermelon and cantaloupes through a face-to-face survey process. In 2008, the process was expanded to include other pest types (plant diseases,
weeds) and their impact on crop yields, grower economics and pesticide use.
