Primary Assay — Desert Locust
Phase Transition (Solitary↔Gregarious)
Schistocerca gregaria
Crowding shifts solitary locusts to gregarious behavior within hours. Attraction to conspecifics, color, and activity benchmark phase state.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Schistocerca gregaria.
| Parameter | Unit | Description |
|---|---|---|
| Conspecific attraction index | ratio | Approach to dummies |
| Activity level | cm/min | Locomotion |
| Color score | index | Body coloration shift |
| Aggregation density | individuals/m² | Group cohesion |
