一个概念模型的基础上开发的两个基本的空间要素的区域范围内的综合虫害管理（AW-IPM），一个核心区和一个缓冲区，以确定保护区的最小规模的程序是技术上可行的，经济上合理的。该模型由生物部分（昆虫扩散）和经济部分组成。生物部分使用随机游走和扩散方程来描述昆虫的扩散，并确定保护核心区不受外来害虫入侵所需的缓冲区的最小宽度。在经济部分，计算核心区域的大小，以确定核心区域的收入等于控制成本的点。这一模型需要针对每个物种和地理位置进行校准和验证。采采蝇和地中海果蝇作为案例研究来说明该模型。
A conceptual model was developed based on the two basic spatial elements of area-wide integrated pest management (AW-IPM), a core area and a buffer zone, to determine the minimum size of the protected area for the program to be technically feasible and economically justifiable. The model consisted of a biological part (insect dispersal) and an economic part. The biological part used random walks and diffusion equations to describe insect dispersal and to determine the minimum width of the buffer zone required to protect the core area from immigration of pests from outside. In the economic part, the size of the core area was calculated to determine the point at which the revenues from the core area equal the control costs. This model will need to be calibrated and validated for each species and geographic location. Tsetse flies and the Mediterranean fruit fly are used as case studies to illustrate the model.
