Internal and external drivers interact to create highly dynamic mosquito blood-feeding behaviour

Area of Science:

• Entomology
• Vector Biology
• Disease Ecology

Background:

• Mosquito blood-feeding is crucial for reproduction and pathogen transmission.
• External factors (light, temperature, humidity, interactions) and internal physiology (hormonal pathways) influence blood-feeding.
• Human activities like insecticide use and climate change impact mosquito behavior.

Purpose of the Study:

• To review and synthesize current knowledge on mosquito blood-feeding behavior.
• To identify knowledge gaps, particularly concerning lifespan changes and diverse environmental conditions.
• To emphasize the need for integrating internal physiology with external factors in epidemiological models.

Main Methods:

• Literature review focusing on mosquito blood-feeding drivers.
• Analysis of factors influencing host-seeking and selection.
• Examination of physiological and environmental influences on behavior.

Main Results:

• Mosquito blood-feeding exhibits remarkable adaptability.
• Significant knowledge gaps exist regarding determinants of host use and lifespan variations.
• Current understanding is biased towards a few tropical species, potentially skewing insights.

Conclusions:

• Integrating internal physiological factors with external environmental influences is critical for accurate disease transmission modeling.
• Further research is needed on understudied mosquito species and lifespan dynamics.
• A comprehensive approach is essential for effective mosquito-borne disease control in a changing world.
