Comparative analysis of sterile mosquito release strategies based on a population suppression model

Year: 2024

Type: article

Abstract: In this paper, we proposed a model for suppressing mosquito populations, evaluating various release strategies for sterilized mosquitoes, including constant continuous release, open-loop control, closed-loop control, and composite control strategies. We established release amount thresholds for each strategy to ensure the ultimate extinction of the wild population. Through numerical simulations, we validated our theoretical results and assessed the efficacy of each strategy. The results indicated that the closed-loop control mechanism significantly enhanced population suppression effectiveness. Higher intensity control notably shortened the control duration, and strategies that incorporated shorter release periods and more frequent population assessments markedly reduced the cumulative release quantity. Furthermore, we found that, compared to closed-loop control, the composite control strategy reduced single release amounts but did not show advantages in other aspects at low control intensities. However, it significantly decreased the cumulative release quantity at high control intensities.
