Abstract This paper monitored the population dynamics of Bemisia tabaci cryptic species and status of its carrying TYLCV and ToCV in Foshan，Guangdong Province．The results of species identification showed that the population of B. tabaci from Sanshui District was MED cryptic species，and population from Chancheng District，Nanhai District，and Shunde District were mixture of MED and MEAM1．The results of monitoring virus carried rate indicated that B. tabaci populations collected from 6 locations of Foshan all carried TYLCV and ToCV．The TYLCV carrying rates，except Shimen Middle School in Shishan Town，were all above 50%．The ToCV carrying rates，except Danzao town，all reached 100%．Thus，high attention should be paid to the rapid expansion of TYLCV and ToCV transmitted by B. tabaci in Foshan．
