A periodic delay single-species difference system with
feedback control is established. With the help of analysis method and Lyapunov
function, a good understanding of the permanence and global attractivity of the
system is gained. Numerical simulations are presented to verify the validity of the
proposed criteria. Our results show that feedback control has no influence on the
permanence while it has influence on the global attractivity of the system.
