Although experimental and observational studies have shown that microparasites can induce the deterministic reduction, fluctuation and extinc-tion scenarios for its host population, most existing host-parasite interaction models fail to produce such rich dynamical behaviors simultaneously. We ex- plore the effects of explicit dynamics of parasites under logistic host growth and different infection rate function. Our results show that the explicit dynamics of parasites and standard incidence function can induce the host density fluctuation and extinction scenario in the case of logistic host growth.
