Behavioral responses of the potato psyllid (Hemiptera: Triozidae) to volatiles from dimethyl disulfide and plant essential oils
Journal of Insect Behavior 26 (3), 336-351
Abstract: The behavioral responses of the potato psyllid, Bactericera cockerelli (Sulc) to dimethyl disulfide (DMDS) and to 12 plant essential oils were examined in a glass Y-tube olfactometer. DMDS at doses of 0.5, 1, 2 and 5 g showed a significant repellent effect on the psyllids. Cedar wood, lime, savory, thyme and tea tree oils significantly repelled adults over a wide range of doses tested (1, 10, 100, 500, 1,000 and 2,000 μl). The oils of clove and peppermint also had a significant repellent effect on adults at all doses except at the lowest dose (1 μl). The residual effect of 1 g of DMDS persisted for 10 consecutive days whereas five oils (thyme, tea tree, peppermint, savory and clove) remained repellent for the 20-day longevity residual trial.
