Trap Design Traps come in a variety of shapes, sizes, and colors.[Read More…]
If you work or have worked with specialty crops, we are reaching out for your help. To develop a scouting protocol for twospotted spider mite management, we are aiming to identify the limit of detection of this pest by growers. We are hoping that you will take 5-10 minutes to complete a survey displaying a[Read More…]
