- The 2nd generation of 12-spot beetles has emerged, and activity will likely remain high through September. Sweep ﬁelds with a sweep net to accurately assess population levels. Take a minimum of four samples (ten arcs of the net per sample) from different parts of the ﬁeld. Beetles tend to concentrate on ﬁeld edges. At this time of year, adult beetles are pests within snap bean and squash fields. They feed on folliage and developing pods.
- There has been a boom of adult diamondback moths detected in pheromone traps. Development will be rapid under warm temperatures. Intensify field scouting so that treatments can be applied to avoid contamination.
