Its relatively efficient mode of action has made it a research direction that has attracted much attention in the prevention and control of mosquito-borne diseases. However, how to optimize the release strategy to make it more feasible and safer in practical applications still requires further in-depth studies. Through the ecological modeling of Culex quinquefasciatus and the optimization study of gene-driven release strategies, its role in the ecosystem can be better understood, providing scientific basis for the application of gene-driven release technology (Lopes et al., 2019). The aim of this study is to deeply explore the application of gene-driven release strategies in the control of bearded mosquitoes and seek to optimize the strategies to improve the prevention and control effects through the introduction of ecological models. In order to better understand and optimize the gene-driven release strategy, ecological models will be used as the basis of analysis in this study. Ecological models can help simulate the dynamic changes of mosquito populations under different environmental conditions and provide a scientific basis for optimizing gene-driven release strategies. This approach is expected to realize the sustainability and controllability of gene-driven release in a wider range of environments. This study will delve deeper into the importance of bearded mosquitoes and the diseases they transmit, introduce the potential advantages of gene-driven release strategies, and clarify the research objectives and the role of ecological models in optimizing the strategies. 1 Ecological Modeling and Its Application to Gene Drive Release 1.1 Overview of ecological modeling Ecological modeling is a tool for describing and simulating species interactions and dynamic changes in ecosystems. In the field of biology, ecological models are widely used to study biodiversity, energy flow, species distribution and other ecological processes. Through mathematical and statistical methods, ecological models can provide an understanding of complex ecosystems and provide ecologists with a basis for prediction and management (Huang and Jin, 2023). Ecological modeling plays a key role in the study of mosquito population dynamics. By simulating elements such as environmental factors, food chain relationships, and reproductive mechanisms, ecological models can help to understand seasonal changes in mosquito population size, patterns of geographic distribution, and responses to external disturbances. This provides important information for the optimization of gene-driven release strategies. 1.2 Basic principles of gene-driven release Gene-driven release is a strategy that utilizes genetic engineering technology to change the genetic structure of wild populations. The basic principle is to introduce specific genes to be transmitted in mosquito populations, thereby altering specific traits of the target species, such as preventing them from transmitting diseases or limiting their reproduction. This strategy uses a genetic "drive" to facilitate the spread of a desired genetic change in a population. Using gene editing techniques, scientists have designed and constructed Culex quinquefasciatus with a specific genetic variant that may include regulation of reproduction, survival, or other physiological traits in order to cause the target mosquito to exhibit the desired trait (Liu and Teng, 2023). Rigorous laboratory testing and validation ensures that the effects of the introduced genetic variation on mosquitoes are controlled, stable, and do not have maladaptive effects on other organisms. This step is critical to the successful application of gene-driven release technology and requires a full understanding of the biology and ecology of the target mosquito. By releasing gene-edited mosquitoes, they are mated with wild mosquitoes. Since these mosquitoes carry gene drive elements, the offspring after mating will carry the corresponding gene variants. In this way, the target gene will be gradually spread in the mosquito population. Through continued release and reproduction, the targeted gene gradually achieves targeted transmission in the population, altering the characteristics of the targeted mosquito population. This could include reducing the ability to transmit disease, controlling the population size, etc., thus achieving the goal of biological control.
