[Identification of a new invasive Q biotype of Bemisia tabaci (Hemiptera: Aleyrodidae) in Taiwan by molecular markers]
Formosan Entomologist 28 (3-4), 211-224
Abstract: Bemisia tabaci (Gennadius), among the top 100 world's worst invasive alien species, causes serious agricultural damage. It is divided into many biotypes. Biotype Q, which originated in the Mediterranean region, is a new invader in Taiwan which has been transmitted by poinsettia and has caused great economic losses in the USA, Mexico, China, and Japan. In this study, 481 samples were collected in Taiwan. Molecular markers indentified not only the indigenous An and Nauru biotypes and the invasive B biotype but also the new invasive biotype Q were found. Sequence characterized amplified region (SCAR) analysis, cleaved amplified polymorphic sequence (CAPS) markers, and a phylogenetic tree based on the mitochondrial cytochrome oxidase I (COI) support the new invasive biotype Q being present in Taiwan. However, biotype Q is not being monitored in the field, and we hypothesize that it is in the early stages of invasion. Biotypes B and Q of B. tabaci have different inherent levels of resistance to insecticides, thus their coexistence will not be easy to control. Therefore, a quarantine of agricultural crops will be necessary to prevent future multiple invasions of biotype Q in Taiwan and avoid potentially serious agricultural economic losses.
