Overview
- MIT and Georgia Tech released a peer-reviewed model and a public interactive app that forecast mosquito trajectories under different sensory cues.
- The model defines three behaviors: fast visual ‘fly-by,’ CO2-driven ‘double-take,’ and sustained ‘orbiting’ when visual and chemical cues co-occur.
- Combined visual and CO2 signals produce a distinct circling response rather than a simple sum of single-cue behaviors, according to the analysis.
- Researchers tracked female Aedes aegypti in 3D around spheres emitting visual or CO2 cues and a protected human volunteer, generating over 53 million data points and 477,000 flight paths.
- Authors say the findings can guide specifically calibrated, multisensory lures and suggest time-varying strategies for suction traps to improve capture rates.
