Distribution of <I>Bemisia tabaci</I> (Hemiptera: Aleyrodidae) Biotypes in Florida–Investigating the Q Invasion

Viral infection of tobacco plants improves performance of Bemisia tabaci but more so for an invasive than for an indigenous biotype of the whitefly

“…Two major recent events associated with B. tabaci have been the widespread invasion of the B biotype of the whitefly [also known as the silverleaf whitefly Bemisia argentifolii (Perring et al, 1993)] from its presumed origin in the Mediterranean-Asia Minor region to much of the rest of the world in the past 20-25 years (Brown et al, 1995;Boykin et al, 2007;Liu S.S. et al, 2007), and the rapid, widespread invasion of the Q biotype from its presumed origin in the Mediterranean region to other parts of the world from 2003 to 2008 (Horowitz et al, 2003;Chu et al, 2006;Ueda and Brown, 2006;Martinez-Carrillo and Brown, 2007;Mckenzie et al, 2009). In many regions of the world, epidemics of plant diseases caused by begomoviruses transmitted exclusively by B. tabaci have been occurring soon after the invasion of the B and Q biotypes of the whitefly (Varma and Malathi, 2003;Seal et al, 2006;Hogenhout et al, 2008).…”

Bemisia tabaciBiotype Q Determined for the First Time on Poinsettia Crops in Finland and Sweden

“…Of these, biotype B (currently B. tabaci Middle East-Asia Minor 1, or MEAM1) spread globally in 1986-1992 (Bedford et al 1994), whereas biotype Q (B. tabaci Mediter-ranean, or Med) started spreading within Europe in the 1990s (Perring 2001, Rauch & Nauen 2003, reached other continents in the 2000s (e.g. Chu et al 2006, Ueda & Brown 2006, Hsieh et al 2007, McKenzie et al 2009, Dennehy et al 2010, Grille et al 2011, possibly due to increasing resistance to neonicotinoids and other insecticides (Fernández et al 2009, Dennehy et al 2010, Luo et al 2010, Wang et al 2010, Sun et al 2013. Following its introduction to new areas, B. tabaci Med is replacing the previously common B. tabaci MEAM1 (e.g.…”

Insights into the transcriptomics of polyphagy: Bemisia tabaci adaptability to phenylpropanoids involves coordinated expression of defense and metabolic genes

“…The focus of this study was the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), which is a polyphagous (generalist) agricultural pest of field and horticultural crops world-wide (McKenzie et al, 2004(McKenzie et al, , 2009). Our experimental system utilized transgenic N. tabacum plants that constitutively express the PAP1/ AtMYB75 transcription factor which was shown to activate, relatively specifically, the phenylpropanoid/flavonoids biosynthetic pathway (PAP plants) (Tohge et al, 2005).…”
