Results of pheromone and sticky trap catches can be viewed
here. Corn earworm: CEW moth activity remains low, but activity increased last week Dome Valley and Roll. Beet armyworm: Beet armyworm moth activity picked up in most trap locations to levels comparable to November. Cabbage looper: Cabbage looper moth activity is increasing throughout the area, and reached fall-like levels in the Wellton and Dome trap locations. Whitefly: Adults captures on sticky traps continue to be at seasonal low levels. Thrips: Thrips movement increased in the past 2 weeks consistent with warmer weather and shrinking lettuce acreage; normal for this time of the year. Aphids: Aphid trap catches were high in some areas of the Yuma Valley indicating that they will most likely begin showing up on seedling cotton and melons. Leafminers: Adult fly movement is increasing in Dome Valley and Yuma Valley, as is normal this time of the year. Diamondback moth: Moths remained very active in many Yuma Valley traps locations, and beginning to show up in higher numbers in the Gila Valley and Wellton. Numbers in general are significantly higher than trap capture during this time period from 1999-2001. Overall, DBM flight activity remains highest in the north Yuma Valley in traps near recently disked-broccoli or seed crop plantings.
