The strawberry aphid Chaetosiphon fragaefolii (Hemiptera: Aphididae) is one of the main pests of the crop, causing significant economic damage. There are synthetic insecticides for aphid control. However botanical insecticides from aromatic plants and essential oils may present potential to repel or kill these insects. The objective of this work was to test the lethal effect of Eucalyptus dunni essential oil (3%), as well as the action of the commercial products Matrine®, Prev-am®, Boveril®, Prev-am®+Boveril® and Pirate® on nymphs of strawberry aphid. E. dunni essential oil (EO) was obtained from fresh leaves by the hydrodistillation process in a Clevenger graduated apparatus. The chemical composition of E. dunni EO was analyzed by gas chromatography. For the bioassay, strawberry leaves infested with 10 nymphs per leaflet were used. 1mL of each sprayed treatment was used on each leaflet. The design used was completely randomized, with seven treatments and five replications. The major compounds in the E. dunni EO were α-pinene (15.51%) and 1,8-cineol (50.33%). Mortality was assessed every 24 hours for three consecutive days. The E. dunni EO showed a mortality rate of 88%, similar to commercial products Prev-am® (98%), Matrine® (98%) and Prev-am®+Boveril® (100%), showing efficacy in controlling C. fragaefolii in laboratory.
