How did this year’s Navel Orangeworm (NOW) trends shape up in the Central Valley? With the largest trapping network in the region, we’ve gathered a season’s worth of data to help answer that question.

The following report covers the Central Valley, which is divided into 10 regions. Each region is supported by a minimum of 50 camera traps. This view shows how NOW pressure has varied throughout the season.

Understanding the Graph

  • The graph below shows daily captures from each region.
  • Blue bars indicate the total number of active traps each day.
  • Green bars represent traps that specifically captured NOW moths.

Key Observations

Spring populations were high across the Valley, but the northern regions (1–3) and region 7 didn’t see a decline in subsequent flights. There were heavy third and fourth flights in the northern valley. We continue to see the trend of these flights merging, creating constant NOW pressure in the latter part of the season.
