The ecology of Aphis craccivora Koch and Subterranean Clover Stunt Virus in south-east Australia. II. A model of cowpea aphid populations in temperate pastures.
In the work reported in this part of a series [cf. RAE/A 60, 2210], various components of the biology of Aphis craccivora Koch, the subterranean clover stunt virus and their host-plant (subterranean clover (Trifolium subterraneum) or burr medic (Medicago polymorpha)) were assembled in a simulation model, and the relation is examined against a profile of a temperate environment. It is concluded that the species is primarily a warm weather species and that is is not adapted to breed in the temperate climate of south-eastern Australia. The potential of different types of mortality factors is also examined.
