Abstract
The structure of equations for a model of the dynamics of a forest population of leaf-eating insects is proposed. For the construction of the model and its experimental testing, the population of the green oak-leaf roller ( Tortrix viridana L.)—one of the most dangerous pests of oak stands—was taken. The explicit form of the main functional relations between the model variables, and also the methods of evaluation of some parameteres and coefficients are given. Experimental and calculated curves obtained by simulation of the oak-leaf roller development process in two foci of infection, from 1969 to 1976, are presented graphically. The suggested dynamics model of the relationship between leaf-eating insects population and foliage of the stand is based on a generalisation of presentations about the oak-leaf roller's biology and ecology, obtained by analysis of experimental and literature data.
