摘要：

In the Canberra region [Australia] the larvae of the Australian bushfly [Musca vetustissima Walker] feed in cattle dung, and the quality of this dung is an important determinant of the population dynamics of the insect. A measure of this quality is provided by the mean mass of puparia reared under standard conditions in the laboratory. A simulation model is presented by means of which this measure and its seasonal variation can be predicted from standard observations of rainfall, temperature and 09h00-humidity. The model is based on the growth index of Fitzpatrick and Nix [1970], but incorporates a simple model for the phenological changes occurring in the pasture from which the dung derived. The model successfully simulates the masses of pupae reared in dung derived from a number of distinct pastures within 200 km of Canberra throughout the seasons 1970-71, 1971-72 and 1972-73.
