Results of pheromone and sticky trap catches can be viewed here.

Corn earworm: Moth activity remains seasonably low, similar to this time last season.

Beet armyworm: Moth activity has reached its lowest level this season, even with above normal temperatures.

Cabbage looper: Similarly, cabage looper moth activity has reached its lowest level this season, but numbers are higher than this time last year.

Whitefly: Adults captures on sticky traps remain seasonably low, similar to last season.

Thrips: Thrips activity is at seasonably low levels at all trap locations.

Aphids: Trap activity the lowest we’ve seen it this fall/winter, but have been picking up green peach aphids on the traps.

Leafminers: Adult activity at seasonal low levels at all trap locations.

Diamondback moth: Activity is generally down relative to earlier in the fall. Activity in some locations was comparable to what we observed in 1998-1999 in the Yuma and Gila Valleys.
