Abstract

In order to further understand the pheromone-oriented walking of the male silkworm moth Bombyx mori, we have analyzed the movement of free walking males in a laboratory wind tunnel using a continuous pulsed stimulation of various frequencies with pheromones. Single and brief pulsed stimulation (100 msec) with pheromones to either antenna elicited a long-lasting zigzag turing pattern (≤4 sec) which consisted of left and right turns or vice versa. The direction of the first turn of the zigzag turning was strongly related to which antenna was stimulated. While continuous pulsed stimulation was applied, similar zigzag turnings to those triggered by a single pulsed stimulation were repeatedly observed with each stimulation. The tempo and the angle of the zigzag turning gradually increased turn by turn and were successively reduced with each stimulation. We exposed two control mechanisms during upwind walking to the pheromone odor source: (1) a self-generated zigzag turning program triggered by a pulsed pheromonal stimulation, and (2) reset mechanisms of this program. We propose that walking B. mori males use similar control mechanisms for movements toward a pheromone source to those of flying moths.
