The green peach aphid, Myzus persicae (Homoptera: Aphididae) and the tobacco flea beetle, Epitrix hirtipennis (Coleoptera: Chrysomelidae) are serious pests of tobacco in Virginia. Recently tobacco producers have used imidacloprid (Admire 2F) as a preventative treatment for control of these pests. Several other neonicotinoids are now being developed for use on tobacco as transplant and foliar treatments. These include thiamethoxam (Platinum and Actara), flonicamid and clothianidin. This study was conducted to assess tobacco flea beetle and green peach aphid control with these new chemicals and to determine the resulting impact on tobacco yield. Thiamethoxam, imidacloprid and clothianidin applied to the seedlings at or before transplanting usually provided excellent control of aphids and flea beetles. Foliar applications of flonicamid gave excellent control of aphids. Information from 2003 tests will also be included.
