The systems approach, utilizing detailed system conceptualization and iterative simulation model development, was used to help direct field and laboratory research on the population dynamics of the onion maggot, Delia antiqua (Meigen) (Diptera: Anthomyiidae) and its naturally occurring fungal pathogen Entomophthora muscae (Cohn) (Entomophthorales: Entomophthoraceae) in the onion agro-ecosystem. The structure and interconnections of this biological system, including an alternate disease host (Delia platura, the seed corn maggot), are outlined as are additional relationships between these components of primary interest and other components closely associated within the onion agro-ecosystem. A structural approach to model development was used as a base for system design and analysis. The model structure and simulation methodology, including program verification and model validation, are described. Examples of simulation results are presented to illustrate the application of the model.
