Areawide Insect Trapping Network (November 1, 2017)
Results of pheromone and sticky trap catches can be viewed here.

Corn earworm: Moth activity remains low, and at levels similar to last season.

Beet armyworm: Moth activity was comparable to catches this time last season. Appear to be most active in the Gila Valley.

Cabbage looper: Cabbage looper moth decreased in the past two weeks, but moths on average are more active than this time last year.

Whitefly: Adults captures on sticky traps increased in many trap locations, and particularly near fields where melons are being harvested.

Thrips: Thrips activity remain lows at most trap locations with the exception of the Texas Hill area where harvested melon fields are being disked under.

Aphids: Aphid activity increased significantly in the past 2 weeks in the North Gila Valley and slightly more in the N. Yuma Valleys consistent with the high winds coming out of the North. Aphids numbers are much higher than what we observed this this time last year.

Leafminers: Adult activity increased significantly in the Tacna / Wellton area over the past 2 weeks consistent with melon harvest.
