In its symbiotic relationship with mosquitoes, Rhodococcus erythropolis can affect the survival, reproduction, and disease transmission abilities of mosquitoes through various mechanisms, playing a significant role in mosquito population control. Understanding these ecological mechanisms is crucial for exploring the potential of Rhodococcus erythropolis as a biological control method and for a better comprehension of the biological interactions within ecosystems. 2 Mosquito Control Efficacy and Limitations 2.1 Efficacy assessment of Rhodococcus erythropolis in mosquito control As a potential biological control method, Rhodococcus erythropolis has attracted widespread attention in recent years. Researchers have conducted a series of experiments and field studies to assess the efficacy of Rhodococcus erythropolis in mosquito control. Here are some findings on its efficacy in mosquito control: Reduction in Mosquito Numbers: Studies have found that Rhodococcus erythropolis can effectively reduce mosquito populations by inhibiting the growth and development of mosquito larvae, showing statistically significant results in some trials. Control of Mosquito Infectivity: The antibiotics secreted by Rhodococcus erythropolis can reduce the number of potential pathogens inside mosquitoes, thereby lowering the risk of mosquitoes as vectors for disease transmission, which is significant for controlling mosquito-borne diseases (Garrido et al., 2020). Impact on Mosquito Reproduction: Certain strains of Rhodococcus erythropolis can affect mosquito reproductive capabilities, leading to reduced reproductive success rates, which helps control mosquito population growth. Despite these positive effects, Rhodococcus erythropolis as a mosquito control method still faces challenges and limitations. 2.2 Limitations and potential issues of Rhodococcus erythropolis Environmental Uncertainty: The efficacy of Rhodococcus erythropolis may be affected by environmental uncertainties. Climate, soil, and ecosystem differences in various regions may impact the survival and reproduction of Rhodococcus erythropolis, thereby affecting its mosquito control efficacy. Potential Impact on Other Insects: Although Rhodococcus erythropolis shows antibiotic secretion and nutritional competition abilities in its symbiotic relationship with mosquitoes, its potential impact on other insects requires further investigation. Rhodococcus erythropolis might interfere with the ecological roles of other insects, having adverse effects on ecosystems. Production and Release Challenges: Mass production and effective release of Rhodococcus erythropolis are challenging. Ensuring a sufficient quantity of Rhodococcus erythropolis near mosquito breeding sites and releasing it at appropriate times and locations require suitable strategies and technologies. Potential Resistance Issues: Like chemical insecticides, long-term use of Rhodococcus erythropolis might lead to mosquito resistance, potentially weakening its efficacy as a mosquito control method (Yu et al., 2023). Uncertainty in Ecosystem Impact: While Rhodococcus erythropolis may be beneficial for mosquito control, its impact on ecosystems remains uncertain, necessitating more ecological research to assess potential ecological risks. 2.3 Other environmental factors affecting application efficacy Besides the inherent limitations of Rhodococcus erythropolis, other environmental factors might affect its efficacy in mosquito control. Here are some environmental factors that could constrain the application efficacy of Rhodococcus erythropolis:
