Interpretive Summary: The sweetpotato whitefly is a worldwide pest of horticultural crops. Whitefly feeding is directly harmful to crop plants. In addition, tomato yellow leaf curl virus (TYLCV) is transmitted exclusively by this whitefly during feeding. This report describes the effects of TYLCV on whitefly dispersal and management implications for both whitefly and TYLCV. This information will be useful for growers, extension agents, crop scouts, researchers and regulatory officials.

Technical Abstract: Bemisia tabaci MEAM1 (Gennadius) (Hemiptera: Aleyrodidae), the sweetpotato whitefly, is a worldwide pest of horticultural crops including tomato. Whitefly feeding directly damages tomato plants and also leads to infection with tomato yellow leaf curl virus (TYLCV), one of the most destructive tomato viruses worldwide. This study examined dispersal of viruliferous vs. non-viruliferous whiteflies on non-infected tomato plants, and non-viruliferous whiteflies on TYLCV-infected vs. non-infected tomato plants. Results indicate that a combination of environmental and human factors likely influence whitefly dispersal and the spread of TYLCV.
