  • Non-host volatiles as repellents for conifer-infesting bark beetles
    Patent number: 6217891
    Abstract: This invention relates to the use of volatiles from the bark of non-host angiosperm trees to protect coniferous trees from attack by bark beetles. Individual compounds or mixtures selected from 18 non-host bark volatiles, identified by coupled gas chromatographic-electroantennographic detection analysis, and deployed alone or with an antiaggregation pheromone or a green leaf volatile, or mixture thereof, are demonstrated to repel conifer-infesting bark beetles from attractant-baited traps, and to protect attractant-baited trees from attack.
    Type: Grant
