Interpretive Summary:

Technical Abstract: The sweetpotato whitefly, Bemisia tabaci is a major insect pest of vegetables world-wide. We evaluated the effect of commercial plant oils – garlic oil, hot pepper wax, and mustard oil against B. tabaci. Cucumber plants served as the control. Additional treatments included no plants or oil (clear air). Using an odor-detecting equipment (olfactometer), we measured repellency of these oils to the whitefly. We found that mustard oil and garlic oil showed repellency against the whitefly. In another olfactometer experiment, we measured the effects of arugula (Eruca sativa cv. Nemat) and 2 mustard variety plants, (Brassica juncea cv. Caliente 19 and giant red mustard), as whitefly repellents. Preliminary results showed that mustard and arugula are promising repellent plants against the sweetpotato whitefly. These results indicate that mustard and garlic oils, and mustard and arugula plants can be used as a “push” component in the “push-pull” management of the sweetpotato whitefly in vegetables.
