A Conceptual Model for Assessing the Minimum Size Area for an Area-Wide Integrated Pest Management Program

Table 1

Biological dispersal model parameters used in the models to estimate a minimum area for an area-wide IPM program, including the sterile insect technique.

Parametera	Units	Description	Notes
𝛽	day^−1b	Birth rate	May vary between fertile and sterile insects
𝛿	day^−1	Death rate	May vary between fertile and sterile insects
𝜎	—	Sterile male competitiveness	Dimensionless. Ranges from 0 to 1
𝐷	km^2day^-1	Diffusion coefficient	Scales the rate of population spread. May vary between fertile and sterile insects
𝑅	indc km^-2day^-1	Sterile release rate
𝐴	ind km^-2	Ambient population density	Used to estimate density dependence parameters

aAdditional parameters will be necessary to model density-dependent population growth and will be species specific.
