Repellency of Rosemary Oil Against Myzus persicae in a Laboratory and in a Screenhouse

"Aphids were released in a screenhouse and allowed to choose between tobacco plants in an area permeated with rosemary oil odor and plants in a control area. The number of aphids in the treatment area was about 70% of that in the control area. These results indicated that the landing of M. persicae on host plants was influenced by odors and that it may be possible to control aphids with repellents."
