| contents | Modeling the effects of insecticides and external effortson crop production A.K. Misraa Rahul Patela1,2 Navnit Jhab Matemáticas stability crop production external efforts Hopf bifurcation Mathematical model In this paper a nonlinear mathematical model is proposed and analyzed to understand the effects of insects, insecticides and external efforts on the agricultural crop productions. In the modeling process, we have assumed that crops grow logistically and decrease due to insects, which are wholly dependent on crops. Insecticides and external efforts are applied to control the insect population and enhance the crop production, respectively. The external efforts affect the intrinsic growth rate and carrying capacity of crop production. The feasibility of equilibria and their stability properties are discussed. We have identified the key parameters for the formulation of effective control strategies necessary to combat the insect population and increase the crop production using the approach of global sensitivity analysis. Numerical simulation is performed, which supports the analytical findings. It is shown that periodic oscillations arise through Hopf bifurcation as spraying rate of insecticides decreases. Our findings suggest that to gain the desired crop production, the rate of spraying and the quality of insecticides with proper use of external efforts are much important. 2021 artículo científico 1392-5113 https://www.redalyc.org/articulo.oa?id=694173172002 https://www.redalyc.org/journal/6941/694173172002/ https://www.redalyc.org/journal/6941/694173172002/html/ https://www.redalyc.org/journal/6941/694173172002/694173172002.epub https://www.redalyc.org/journal/6941/694173172002/movil https://doi.org/10.15388/namc.2021.26.24442 en http://www.redalyc.org/revista.oa?id=6941 Nonlinear Analysis: Modelling and Control application/pdf Vilniaus Universitetas Nonlinear Analysis: Modelling and Control (Lituania) Num.6 Vol.26 |
