The lotka-volterra model is one of the earliest predator-prey models to be based on sound mathematical principles it forms the basis of many models used today in the analysis of population dynamics unfortunately, in its original form lotka-volterra has some significant problems.
The lotka-volterra equations, also known as the predator-prey equations, are a pair of first-order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its.

This paper investigates the complex dynamics of a harrison-type predator-prey model that incorporating: (1) a constant time delay in the functional response term of the predator growth equation and (2) environmental noise in both prey and predator equations. We found strong impacts of the strength and duration of disturbances on the transient dynamics and recovery time of predator and prey, and strong differences among the dynamics of the two species due to their position in the food web. The relationship between predators and their prey has always occupied a special place in the minds of ecologists, and the great interest in predator-prey systems makes them an ideal case for system dynamics. Predator-prey dynamics covers a subject that has not received enough attention by animal behavior and ecology researchers conover's book has laid the foundation for future research on olfactory predators and their prey.

Of insect predator—prey dynamics is the difference in the lower tempera-ture thresholds of the predator and prey as the ladybird's lower tempera. Objectives: to understand the basic concept of prey-predator dynamics using the established mathematical model of lotka-volterra equations, ie, how predators affect prey populations, and vice-versa.
