Extinction Criteria in Stage-Structured Population Models with Impulsive Culling
We propose stage-structured population models for species whose adult members are subject to culling, with a view to understanding the culling regimes that are likely to result in eradication of the species. A purely time-dependent model is proposed in which culling occurs at particular discrete times, not necessarily equally spaced. Then a reaction-diffusion model is proposed for a situation i...
متن کاملOn impulsive integrated pest management models with stochastic effects
We extend existing impulsive differential equation models for integrated pest management (IPM) by including stage structure for both predator and prey as well as by adding stochastic elements in the birth rate of the prey. Based on our model, we propose an approach that incorporates various competing stochastic components. This approach enables us to select a model with optimally determined wei...
متن کاملStability and Permanence of a Pest Management Model with Impulsive Releasing and Harvesting
and Applied Analysis 3 (1) V is continuous in ((n − 1)T, (n + τ − 1)T] × R + , ((n + τ − 1)T, nT] × R + and for each x ∈ R + , n ∈ N, lim (t,y)→ ((n+τ−1)T + ,x) V(t, y) = V((n + τ − 1)T + , x) and lim (t,y)→ (nT + ,x) V(t, y) = V(nT, x) exist. (2) V is locally Lipschitzian x. Definition 1. Letting V ∈ V 0 , one defines the upper right derivative of V with respect to the impulsive differential s...
متن کاملExtinction and Permanence of a Three-Species Lotka-Volterra System with Impulsive Control Strategies
A three-species Lotka-Volterra system with impulsive control strategies containing the biological control the constant impulse and the chemical control the proportional impulse with the same period, but not simultaneously, is investigated. By applying the Floquet theory of impulsive differential equation and small amplitude perturbation techniques to the system, we find conditions for local and...
متن کاملExtinction and Permanence of a General Predator-Prey System with Impulsive Perturbations
A general predator-prey system is studied in a scheme where there is periodic impulsive perturbations. This scheme has the potential to protect the predator from extinction but under some conditions may also serve to lead to extinction of the prey. Conditions for extinction and permanence are obtained via the comparison methods involving monotone theory of impulsive systems and multiple Liapuno...
