Tracking Resources through Space and Time; It may be cost-effective to undertake pre-emptive biosecurity activities such as slowing the spread of H. Helicoverpa armigera is recorded from 68 plant families worldwide, but only 14 families are recorded as containing a host in all geographical areas [ 19 ].

Our confidence in the modelled potential distribution presented here is bolstered by the similar distribution of the closely-related H.

In Australia, the apparent southern latitudinal limit for persistent populations was similar for both mechanisms, but the fit elsewhere throughout the poleward range was far better using the degree day model e.

Populations have been high there, impacting significantly on key crops such as corn, soybeans, tomatoes and cotton to name a few [ 5 ].
