ABSTRACT
The correlation between the disease and the prey-predator system is a topic of significant interest, and the joint study of ecology and epidemiology is a relatively new branch of study, known as eco-epidemiology. It is a well-known fact that the predator is more likely to attack the infected prey because the latter gets weaker and less active due to infection, and hence became more vulnerable to the predator. This concept was modeled by various researchers [87, 88, 184, 185]. But, there is also a possibility that the predator gets infected due to consumption of the infected prey and dies out more rapidly. In this case, the growth of the predator will depend on the healthy prey. Further, there will be a lack of the healthy prey due to disease in the prey population and therefore, the predator starts depending on the alternative foods for their
the predator populations take some time to give birth to a new offspring after mating is known as gestation delay. The simplest prey-predator models cannot capture the rich variety of dynamics and the inclusion of the gestation delay in these models makes them more realistic [83, 99-101].
