Observation and experimental analysis of the mating behavior of Xylotrechus pyrrhoderus were carried out. The mating behavior consists of at least two phases : (1) The flying female approaches the resting male, (2) The male is stimulated by the alighting female and copulates with her. Experimental analysis indicated that in the first phase, the female is attracted by the sex pheromone released by the male.
