A thread tethered flight method was developed to analyze insect flight behaviour using straingauge transducers. A moth was tethered by a thread attached to a thin cantilever of phosphorbronze fitted with two strain-gauges. The moth could fly and maneuver within the length of the thread. To record the flight propensity and intensity, a sensor plate was placed horizontally to detect vertical flight movements. The outputs from the sensors were connected to a data analysis system which collected data and automatically integrated and calculated the flight propensity, flight interruption, and peak flight intensity. To record flight direction and pattern, two sensor plates were crossed at right angles and suspended vertically. The unit could detect both back and forth, and right and left movements ; both outputs were recorded simultaneously as oscillographic and synthesized resurgent figures. This system made it possible to quantify the response and turning of the flying moth when exposed to stimuli. The results are represented in three dimensions (flight power, flight direction, and temporal progress).
