Several species of Frankliniella flower thrips are known to vector plant viruses such as Tomato Spotted Wilt Virus (TSWV) in a variety of vegetable crops, often causing significant economic losses to growers. Little is known, however, of their propensity to move about within or between host plant species and how this behavior may be mediated by landscape architecture. A mark-recapture protocol was designed to estimate thrips movement within and between 2 cultivated hosts (cucumber and bell pepper) and 1 wild host (wild radish) in the field in Northern Florida during the spring and summer of 2004. Population dynamics on each host were tracked and results for F. occidentalis, F. tritici, and F. bispinosa were compared. Implications of population dynamics of each thrips species and their movement within and between hosts are discussed.
