Abstract： Discrete host-pathogen models including integrated pest management (IPM) interventions with impulsive effects at both fixed and unfixed times were analysed with regard to host-eradication, host-pathogen persistence and host-outbreak solutions. The condition which guarantees the global stability of host-eradication periodic solution with fixed moments is given. Periodic solutions also exist for models with unfixed moments for which the maximum amplitude of the host is less than the economic threshold. However, the results obtained here indicate that, in practice, it is a very difficult task to control the host population such that its density does not exceed economic threshold.
