Abstract
The number of times that adult females of Heliothis zea (Boddie) captured in ultraviolet-light traps placed in cotton, sorghum and maize fields in the Brazos River Valley of Texas in 1975 had mated appeared to be an index of moth age. Most females taken in maize and sorghum fields in June during the stage of plant development most attractive for oviposition had mated 1-4 times. Females caught in fields of mature maize and sorghum in July and fruiting cotton in July and August were generally young moths with a high fat-body content that were either unmated or had mated only once. The studies indicated that the traps could be used to detect an ovipositional phase of the pest characterised by the accumulation of mated moths in fields of attractive maize and sorghum and a dispersal phase in July and August when adults emerging in fields of mature maize and sorghum were dispersing to cotton, the only major suitable food-plant available during the later period
