PERSISTENCE IN A PREY-PREDATOR SYSTEM WITH DISEASE IN THE PREY

This paper deals with a prey-predator system where the prey population is infected by a microparasite. The predator functional response is a function of the weighted sum of prey abundances. This type of functional response reflects the switching mechanism of the predator. We identify the parameters which influence the persistence of all the populations as well as impermanence. The role of delay in the above system is also discussed.
