Zika virus infection is a vector-borne disease transmitted by Aedes mosquitoes, with humans and mosquitoes as primary carriers. This research examines Zika virus transmission patterns and control measures using five mathematical models, employing dynamical systems stability theory, optimal control theory, and ODE45 numerical simulations. It initiates by investigating the effectiveness and details of increased medical investments, restricted access to infection zones and reducing human-mosquito exposure. Findings reveal that none of these measures alone can control the virus spread in the area. The first model is created by introducing a mosquito-harvesting measure, shown to be effective in reducing virus spread. However, caution is needed when applying this measure alone to prevent disproportionate consequences. Next, a Zika virus transmission model incorporating biodiversity dilution is created to analyze its regulatory role. The research findings indicate that biodiversity can suppre.....
