Pest Control of Jatropha curcas Plant for Different Response Functions

Nowadays Jatropha curcas plants are being considered as a renewable energy feedstock for the production of biodiesel to overcome the crisis of natural fuel. The seeds of this plant contain oil which is one of the significant resources for alternative fuel production i.e. biodiesel. Though Jatropha curcas plant is proven to be toxic to many insects and animals, it is not pest and disease resistant. On this regard our research article presents formulation and analysis of a mathematical model for Jatropha plantation with a view to control its natural pests through application of biological pesticide. We assume linear and hyperbolic functional responses of predator for susceptible pest, where for infected pest the functional response is linear, as infected pests are weaker than susceptible pest and easy to catch. We study the dynamics of the system around each of the ecological feasible equilibrium. The reduction of disease eradication and predator-pest coexistence are observed around the predator free and disease free equilibrium respectively.
