Areawide Insect Trapping Network (October 29, 2014)
Results of pheromone and sticky trap catches can be viewed here.

Corn earworm: Corn earworm moths remain active and were particularly numerous in the Dome Valley, Wellton and near Texas Hill in the past 2 weeks. Compared to this time in 2013, corn earworm is much more active this fall. Unseasonably warm temperature is likely influencing this difference in activity.

Beet armyworm: Beet armyworm moths remain active in most areas, but remain particularly heavy in the Yuma Valley and Dome. Moth activity is similar to trends we saw last fall (2013).

Cabbage looper: Cabbage looper moth activity continues to increase in most area-wide traps, whereas last fall, trap catches began to decline at this time. Again, temperature is likely the reason.

Whitefly: Adult activity continues to decline in all areas, at levels similar to what we experienced in late August. However, larger numbers of whiteflies were still actively moving this time last year, particularly in the N. Gila Valley and Wellton.

Thrips: Thrips numbers in general are beginning to pick up in most areas, and movement remains high in the Yuma Valley. Current trends are similar to what we saw last fall.

Leafminers: Numbers on traps were generally down, except for high numbers of adults captured on the trap located at 47E adjacent to harvesting melons and cotton recently shredded.

Aphids: Alate (winged) aphids are still showing up in traps in lower numbers than previous weeks, and are trap catches have been steady in the N. Gila Valley. An occasional cabbage aphid was found on the traps, all others were species not important to produce crops. Anticipate numbers increasing as temperatures decline and N, NW winds pick up.
