Abstract: | | Helicoverpa punctigera (Wallengren) larvae have been recorded on native non-crop hosts in the inland regions of Australia. However, there are few records of their survival on these non-crop hosts, especially on plants with the C4 photosynthetic pathway. We investigated larval survival on four C4 plant species (Atriplex numularia Lindl. Atriplex vesicaria Heward ex Benth., Portulaca oleraceae L. and Tribulus terrestris L.) and two C3 plant species (Medicago polymorpha L. and Cullen cinereum (Lindl.)) under glasshouse conditions. Larvae fed on all C4 plants, although performance varied among these plants being higher (32.2 ± 6.9 and 31.7 ± 6.9% survival) on the Atriplex plant species and lowest (15.9 ± 7.9% survival) on P. oleraceae. Larval survival was similar between the two Atriplex species. A direct comparison of larval performance between the C4 plant A. nummularia and the known H. punctigera C3 host plants C. cinereum or M. polymorpha suggested that this C4 plant might be a suitable food source in the field, particularly in situations where it is growing nearby to C3 plants as is common in inland Australia.
