Modeling Mosquitoes and their Potential Odonate Predators Under Different Land Uses

Area of Science:

• Ecology
• Conservation Biology
• Public Health

Background:

• Accelerated landscape transformation impacts biotic communities and ecosystem services.
• Odonate insects (damselflies and dragonflies) are generalist predators sensitive to land-use change, making them potential indicators for vector-borne disease control.

Purpose of the Study:

• To identify land uses in Mexico where odonates co-occur with medically relevant mosquitoes.
• To understand the potential role of odonates in natural mosquito control within changing landscapes.

Main Methods:

• Modeled 167 odonate species, 4 mosquito species, and 51 land-use categories across central Mexico's hydrological basins.
• Utilized data mining and complex network analysis to infer spatial co-occurrence patterns.

Main Results:

• Identified the ecological network between odonates and mosquitoes.
• Found that 34% of odonate species co-occur with medically relevant mosquitoes.
• Co-occurrence was observed in both preserved forests (cloud forest, rainforest, dry forest) and human-modified areas (settlements, crop fields, pastures).

Conclusions:

• Odonates show potential for mosquito predation across diverse land uses, including human-dominated environments.
• Community-regional studies are crucial for assessing public health impacts of landscape change.
• Findings support integrating odonate conservation into vector-borne disease management strategies.
