Abstract

Populations of Heliothis punctigera and H. armigera in the arid and semi‐arid rangeland areas of southwestern Queensland and northern South Australia were studied by pheromone and fermentation trapping of adults and by sweep netting of larvae. H. armigera was captured approximately 450 km further inland than previously recorded, but only in low numbers. No evidence of breeding was found. By contrast, H. punctigera was commonly collected, particularly after winter and spring rain. Larvae were found on daisies and other ephemeral plants. The results are discussed in relation to the migratory behaviour of Heliothis spp. and the implications for management in cropping areas. Copyright © 1989, Wi..
