Stage-Structured Impulsive SI Model for Pest Management
نویسندگان
چکیده
An SI epidemic model with stage structure is investigated. In the model, impulsive biological control is taken, that is, we release infected pests to the field at a fixed time periodically. We get a sufficient condition for the global asymptotical stability of the pesteradication periodic solution (0,0, ̃ I(t)), and a condition for the permanence of the system. At last, a brief discussion shows that our results will be helpful for pest management.

A Stage-Structured SI Eco-Epidemiological Model with Time Delay and Impulsive Controlling
This paper formulates a robust stage-structured SI eco-epidemiological model with periodic constant pulse releasing of infectious pests with pathogens. The authors show that the conditions for global attractivity of the ‘pest-eradication’ periodic solution and permanence of the system depend on time delay, hence, the authors call it “profitless”. Further, the authors present a pest management s...
متن کاملA Pest Management Epidemic Model with Time Delay and Stage-Structure
In this paper, an SI epidemic model with stage structure is investigated. In this model, impulsive biological control which release infected pest to the field at a fixed time periodically is considered, and obtained the sufficient conditions for the global attractivity of pest-extinction periodic solution and permanence of the system. We also prove that all solutions of the model are uniformly ...
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 کاملDynamics of a Stage Structure Pest Control Model with Impulsive Effects at Different Fixed Time
Many existing pest control models, which control pests by releasing natural enemies, neglect the effect that natural enemies may get killed. From this point of view, we formulate a pest control model with stage structure for the pest with constant maturation time delay through-stage time delay and periodic releasing natural enemies and natural enemies killed at different fixed time and perform ...
متن کاملIntegrated pest management with stochastic birth rate for prey species
Song and Xiang (2006) developed an impulsive differential equations model for a two-prey one-predator model with stage structure for the predator. They demonstrate the conditions on the impulsive period for which a globally asymptotically stable pest-eradication periodic solution exists, as well as conditions on the impulsive period for which the prey species is permanently maintained under an ...
