b Dispersing males and females of Ips grandicollis , whether mated or virgin, initiated galleries on experimental logs held in a naturally infested P. radiata plantation. A few females initiated galleries despite the presence of adjacent male‐initiated galleries. Males responded to logs bearing females by entering 41% of the female‐initiated galleries. The pattern of entry of these males differed depending on whether the entrance to the female‐initiated gallery was blocked by frass or not. The findings of this study has led to interesting speculations about the behaviour and biology of this species.
