Behavioral Tracking for American Cockroach
Periplaneta americana
Escape behavior, locomotion, and circadian biology in Periplaneta americana. ConductVision delivers automated tracking and quantitative parameter extraction across the full assay catalog below.
Why American Cockroach in Behavioral Research
The American cockroach is a classical model for ultra-fast escape responses driven by giant interneurons, locomotion, and circadian rhythms. Its size, robustness, and well-mapped sensory-motor circuits make it a workhorse of invertebrate neuroethology.

What We Measure in American Cockroach
Validated assays with quantitative parameter tracking for Periplaneta americana.
Cerci-evoked giant-interneuron escape produces an ultra-fast turning response away from puff direction. Latency, turn angle, and accuracy are the canonical readouts.
| Parameter | Unit | Description |
|---|---|---|
| Response latency | ms | Puff to first leg movement |
| Turn angle | deg | Heading change away from wind |
| Run distance | cm | Distance traveled in escape |
| Accuracy index | % | Correct turn direction |

Cockroaches show robust tripod gait and dynamic stability, supporting biomechanics and motor-control research. Speed, gait phase, and turning index motor output.
| Parameter | Unit | Description |
|---|---|---|
| Walking speed | cm/s | Translational velocity |
| Stride frequency | Hz | Step rate |
| Tripod-gait phase | rad | Inter-leg timing |
| Turning rate | deg/s | Heading change |

Periplaneta has a strong circadian rhythm with a nocturnal activity peak. Free-running period and entrainment quantify the optic-lobe pacemaker.
| Parameter | Unit | Description |
|---|---|---|
| Peak activity time | h | Phase of nocturnal peak |
| Free-running period | h | τ in DD |
| Activity onset variance | min | Phase precision |
| Total daily activity | min | Locomotor output |

Cockroaches learn the position of cool refuges in a heated arena. Trials to criterion and target latency benchmark spatial cognition in a non-eusocial insect.
| Parameter | Unit | Description |
|---|---|---|
| Trials to criterion | count | Acquisition speed |
| Target latency | s | Time to reach refuge |
| Reversal learning | trials | Cognitive flexibility |
| Spatial-search efficiency | index | Path length vs optimum |

Cockroaches follow odor plumes (food or pheromone) using surge-and-cast strategies. Path tortuosity and source-localization time index plume tracking.
| Parameter | Unit | Description |
|---|---|---|
| Source localization time | s | To plume source |
| Path tortuosity | index | Search efficiency |
| Cast frequency | casts/min | Out-of-plume turns |
| Surge length | cm | In-plume bouts |
