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.

Non-host volatiles as repellents for conifer-infesting bark beetles

This invention relates to a novel composition for attracting mullein bugs, Campylomma verbasci, a pest of tree fruit orchards in North America. The invention also pertains to methods of attracting mullein bugs and predicting future population levels of these insects. The composition for attracting male mullein bugs, Campylomma verbasci, comprises a mixture of butyl butyrate and 2 (E)-crotyl butyrate.
