. Vibrations of the thorax and electrical activity (EMG) of gypsy moth flight muscles were recorded during wing fanning following pheromone stimulation. The percentage of positive responses and durations of bursts of flight muscle activity increased with the logarithm of pheromone dose, whereas latency decreased. The results correlated well with wing fanning responses of freely moving gypsy moths exposed to nearly identical stimulus conditions. Typical dose‐response curves in the range of 0.04‐400ng disparlure were obtained in both types of experiments. These methods provide an electrical analogue of wing fanning behaviour.
