In 1997, cucumber beetle trap prototypes were tested at Hungry Hollow Farms in Yolo Co., CA, which is north of Winters and west of Woodland. Based on these tests, a modified trap was developed in 1998. The chief characteristics of this trap are: 1) large catch volume, 2) low cost, and 3) potential for mass production using local materials. This report summarizes findings on trap operation and suggests improvements. Beetle behavior and its impact on management is also discussed.
