Corrigendum to “Coexistence states of a Holling type-II predator-prey system” [J. Math. Anal. Appl. 369 (2) (2010) 555-563]

We present the asymptotic behavior of the coexistence states near the point of bifurcation from infinity of the form

Comment on “Existence and stability of periodic solution of a Lotka-Volterra predator-prey model with state dependent impulsive effects” [J. Comput. Appl. Math. 224 (2009) 544-555]

In this paper, according to integrated pest management principles, a class of Lotka-Volterra predator-prey model with state dependent impulsive effects is presented. In this model, the control strategies by releasing natural enemies and spraying pesticide at different thresholds are considered. The sufficient conditions for the existence and stability of the positive order-1 periodic solution are given by the Poincaré map and the properties of the LambertW function.
