Relationships among pheromone trap catches of male corn earworm moths (Lepidoptera: Noctuidae), egg numbers, and phenology in corn



Relationships among pheromone trap catches of male corn earworm moths (Lepidoptera: Noctuidae), egg numbers, and phenology in corn



Canadian Entomologist 1232: 271-281



Relationships among catches of adults of Helicoverpa zea in pheromone traps, numbers of eggs, and maize ears with fresh silks were investigated in 8 maize fields during a 2-year period in Brazos River Valley, Texas. Cross-correlation analysis indicated that the catches of adults in pheromone traps were closely associated with egg numbers in 7 of the 8 fields with a time differential varying between -1 to + 2 days.
