Quantification and Localization of Watermelon Chlorotic Stunt Virus and Tomato Yellow Leaf Curl Virus (Geminiviridae) in Populations of Bemisia tabaci (Hemiptera, Aleyrodidae) with Differential Virus Transmission Characteristics
Bemisia tabaci (Gennadius) is one of the economically most damaging insects to crops in tropical and subtropical regions. Severe damage is caused by feeding and more seriously by transmitting viruses. Those of the genus begomovirus (Geminiviridae) cause the most significant crop diseases and are transmitted by B. tabaci in a persistent circulative mode, a process which is largely unknown. To an...
متن کاملSweet potato leaf curl virus: Efficiency of acquisition, retention and transmission by Bemisia tabaci (Hemiptera: Aleyrodidae)
The sweetpotato whitefly, Bemisia tabaci (Gennadius), vectors numerous plant viruses, including Sweet potato leaf curl virus (SPLCV), a begomovirus. Experiments were conducted on seedlings of an indicator plant, the Brazilian morningglory (Ipomoea setosa Ker Gawl.), and sweet potato [Ipomoea batatas (L.) Lam.] to assess acquisition, retention and transmission of SPLCV by B. tabaci. Assays were ...
متن کاملFemale-Biased Symbionts and Tomato Yellow Leaf Curl Virus Infections in Bemisia tabaci
The female-biased infection of facultative symbionts has been found in Bemisia tabaci; however, whether there are any differences in tomato yellow leaf curl virus (TYLCV) and obligate symbiont infection rates between females and males is unknown. Determining whether such differences exist would be very important for understanding the spread of the plant virus and of the symbionts. We compared b...
متن کاملReplication of Tomato Yellow Leaf Curl Virus in Its Whitefly Vector, Bemisia tabaci.
UNLABELLED Tomato yellow leaf curl virus (TYLCV) is a begomovirus transmitted exclusively by the whitefly Bemisia tabaci in a persistent, circulative manner. Replication of TYLCV in its vector remains controversial, and thus far, the virus has been considered to be nonpropagative. Following 8 h of acquisition on TYLCV-infected tomato plants or purified virions and then transfer to non-TYLCV-hos...
متن کاملTomato yellow leaf curl virus alters the host preferences of its vector Bemisia tabaci
Bemisia tabaci, the whitefly vector of Tomato yellow leaf curl virus (TYLCV), seriously reduces tomato production and quality. Here, we report the first evidence that infection by TYLCV alters the host preferences of invasive B. tabaci B (Middle East-Minor Asia 1) and Q (Mediterranean genetic group), in which TYLCV-free B. tabaci Q preferred to settle on TYLCV-infected tomato plants over health...
