The authors use the properties of $M$-cone and eigenspace of spectral radius of nonnegative matrices to prove a delay differential inequality of Halanay type with impulsive initial condition. Then, they apply such result to obtain an estimate for the exponential stability of the model. An example is given. rv: Marcia Federson (São Paulo)
