Evaluating the effect of seven plant essential oils on pollen beetle (Brassicogethes aeneus) survival and mobility

Plant essential oils (EOs) represent an area of interest for managing agricultural pests. We examined the insecticidal efficacy of seven plant EOs on the survival and mobility of the pollen beetle Brassicogethes aeneus , a primary pest of oilseed rape ( Brassica napus ) in Europe. Topical dosing tests showed the EO of the inner bark of Cinnamomum verum (cinnamon) to be the most effective EO examined in our study. Subsequent bioassays, exposing...
