    Description

    The effect of semiochemical interruptants was examined for Ips latidens (LeConte) and Ips pini (Say) using artificial trees (tall-traps) consisting of an array of seven Lindgren multiple-funnel traps suspended vertically on a rope ladder. S-(+)- Ipsdienol reduced the numbers of I. latidens captured in (±)-ipsenol-baited funnel traps relative to funnel traps immediately above them and to control tall-traps. The combination of (±)-exo-brevicomin and cis- and trans-verbenol reduced the number of I. pini captured in (±)-ipsdienol-baited funnel traps relative to funnel traps immediately above them and to control tall-traps. These results provide support for semiochemical-based pest-management tactics that utilize a point source of interruptant at the base of a tree while noting limitations in behavioural effects and efficacy.
