Behavioral Tracking for Yellow Fever Mosquito
Aedes aegypti
Host-seeking, flight behavior, and vector biology in Aedes aegypti. ConductVision delivers automated tracking and quantitative parameter extraction across the full assay catalog below.
Why Yellow Fever Mosquito in Behavioral Research
Aedes aegypti is the principal vector for dengue, Zika, and yellow fever and a key model for chemosensory and host-seeking behavior. Behavioral assays of CO₂ tracking, host preference, and insecticide response underpin global vector control research.

DeGennaro M, et al. (2013). orco mutant mosquitoes lose strong preference for humans and are not repelled by volatile DEET. Nature, 498(7455), 487-491. PMID: 23719379
What We Measure in Yellow Fever Mosquito
Validated assays with quantitative parameter tracking for Aedes aegypti.
Aedes aegypti integrates CO₂, body heat, and skin odors to locate human hosts. Wind-tunnel and cage assays measure flight initiation, plume tracking, and approach behavior to host cues.
| Parameter | Unit | Description |
|---|---|---|
| Flight activation | % | Fraction taking off to CO₂ |
| Attraction index | ratio | Test vs control approach |
| Plume tracking accuracy | deg | Heading vs odor source |
| Approach latency | s | Cue onset to host contact |

Female Aedes probe and engorge to repletion on host blood. Probing latency, feeding duration, and blood volume index vector competence and pathogen transmission risk.
| Parameter | Unit | Description |
|---|---|---|
| Probing latency | s | Landing to first probe |
| Feeding duration | s | Probe insertion to disengage |
| Blood volume | µL | Mass change |
| Re-feed rate | % | Multiple-host visits |

Gravid females select egg-laying sites by water cues, organic content, and conspecific eggs. Egg counts and visit duration across substrates inform breeding-site control.
| Parameter | Unit | Description |
|---|---|---|
| Egg count per site | count | Substrate preference |
| Visit duration | s | Pre-oviposition exploration |
| Skip-oviposition events | count | Distribution across sites |
| Site-revisit rate | % | Memory for sites |

WHO bottle and tube assays expose mosquitoes to discriminating doses of insecticide. Knockdown time and 24-h mortality benchmark resistance, while behavioral assays detect repellency and irritancy.
| Parameter | Unit | Description |
|---|---|---|
| Knockdown time (KT₅₀) | min | Time to 50% knockdown |
| 24-h mortality | % | Lethal endpoint |
| Excito-repellency | ratio | Time on vs off treated surface |
| Resistance ratio | fold | LD vs susceptible reference |

Aedes aegypti shows bimodal crepuscular flight activity controlled by an endogenous clock. Activity recording quantifies peak times, total flight, and clock-gene phenotypes.
| Parameter | Unit | Description |
|---|---|---|
| Peak activity time | h | Phase of flight peak |
| Total daily flight | min | Activity sum |
| Bimodality index | ratio | Dawn vs dusk peaks |
| Free-running period | h | Circadian τ |
