Implementation of control strategies for sterile insect techniques

Area of Science:

• Entomology
• Mathematical Modeling
• Vector Control

Background:

• Mosquito-borne diseases pose significant public health challenges.
• Effective vector control strategies are crucial for disease prevention.
• Sterile insect technique is a promising method for mosquito population suppression.

Purpose of the Study:

• To develop and analyze a sex-structured entomological model for mosquito control.
• To evaluate the efficacy of sterile male mosquito releases for population elimination.
• To compare different release strategies: constant, periodic impulsive, open-loop, closed-loop, and mixed.

Main Methods:

• Development of a sex-structured mathematical model for Aedes mosquitoes.
• Analysis of periodic impulsive control strategies for sterile male releases.
• Simulation and theoretical analysis of open-loop, closed-loop, and mixed control strategies.
• Derivation of sufficient conditions for population elimination.

Main Results:

• Sufficient conditions for mosquito population elimination were established for different release strategies.
• Open-loop control (constant releases) guarantees elimination under specific release size and frequency conditions.
• Closed-loop control (adaptive releases) and mixed strategies offer enhanced efficiency in terms of time and resource utilization.

Conclusions:

• Sterile male mosquito releases, particularly using periodic impulsive strategies, are effective for vector population elimination.
• Mixed control strategies combining open-loop and closed-loop approaches yield the best results for rapid and resource-efficient elimination.
• The proposed model provides a framework for designing optimized sterile insect release programs.
