Records of Helicoverpa armigera from pheromone and light traps are presented for areas of South Australia and Western Australia where this agricultural pest has not previously been recognised. Although considerably less abundant than H. punctigera, H. armigera was recorded at all trap locations in the two states, many of which were in arid inland areas devoid of agricultural crops. A better definition of the distribution of this species map assist in understanding the dynamics of pesticide resistance in populations within the cropping areas.
