The occurrence of Bemisia tabaci in greenhouses has been monitored in Korea since the first report about the introduction of Q biotype in 2005. The Bemisia tabaci B biotype has occurred only in rose greenhouses of a middle region (Jincheon county) in Korea since 1998. The host plant of the Q biotype, however, was sweet pepper, hot pepper, tomato, eggplant, and cucumber in the southwest (total 24 cities or counties) of Korea. The biotypes and genetic differentiation of the whiteflies collected in each regions were analyzed by mitochondrial 16S DNA and CO1 gene sequences. The Q biotype spread rapidly to other regions from invaded southern region in Korea, and various host plants during the year. Tomato yellow leaf curl virus (TYLCV), however, has not yet been found in tomato or sweet pepper greenhouses in Korea.
