Areawide Insect Trapping Network (October 15, 2014)

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

Corn earworm: Corn earworm moths remain very active in the Dome Valley and have significantly increased in the Yuma Valley where numbers on i11 Oct were above 15 moths per night in both areas. Activity also increased in many of the other areas including the Gila Valley and Wellton.

Cabbage looper/Beet armyworm: Beet armyworm moths are active in most areas, but have been particularly heavy in the Yuma Valley and Dome. Cabbage looper moth activity continues to increase across most areas and was heaviest last week in the south Yuma Valley near the River (Co. 14.5 and Levee Rd) and near Texas Hill (47E). Activity has begun to increase in the south Gila Valley.

Whitefly: Adult activity continues to decline in all areas, except out east near 47E. This trap is located adjacent to fall melons which are approaching harvest.

Thrips: Thrips numbers in general are beginning to pick up in most areas, but movement was particularly heavy 2 weeks ago in Dome Valley.

Leafminers: Slight increases were observed last week in most areas. However, a very high number of adults were captured on a trap located at 47E adjacent to melons.

Aphids: Alate (winged) aphids are beginning to show up on traps, particularly in the Yuma Valley. This is not surprising given the north winds over the past week or so. An occasional cabbage aphid was found on the traps, all others were species not important to produce crops.
