Oscillation in Pest Population and Its Management: A Mathematical Study

Figure 7

Behavior of the system for larger delay . First two figures indicate the time series graphs of the pest and predator population, whereas the bottom one shows the solution curve for initial condition (1, 0.5). These figures show that period of oscillation increases when delay increases. It may be clearly observed from the bottom one that oscillation of pest ( ) is higher than its natural enemy ( ).
