A contact and odor responsive device for trapping khapra beetles and their larvae in which fibrous paper or fabric strips are constructed to provide contact allowing forms containing pheromone attraction means, food attractive means and lethal means for destroying the beetles and a method of using said traps to detect and destroy the beetles and their larvae.

Method for the early detection, localization and control of khapra

A method is described for combating the bark beetle Scolytus multistriatis. The method uses an attractant mixture of three compounds: 4-methyl-3-heptanol; 2,4-dimethyl-5-ethyl-6,8-dioxabicyclo (3.2.1) octane; and .alpha.-cubebene. Traps containing the mixture are set out in or near infested areas. When a sufficient number of beetles have been lured into the traps, they are removed and destroyed. Alternatively, the traps contain an insecticide which enables the traps to remain onsite for a longer period.
