  • Chemical attractant for smaller European bark beetle
    Patent number: 4034080
    Abstract: 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.
