Acyl sugars and whitefly (Bemisia tabaci) resistance in segregating populations of tomato genotypes.
The wild tomato, Solanum pennellii, is an important source of resistance genes against tomato pests. This resistance is due to the presence of acyl sugars (AS), which are allelochemicals that have negative effects on arthropod pests. There are no commercially available tomato cultivars that exhibit significant levels of resistance to arthropod pests. Therefore, this study evaluated resistance t...
متن کاملInsecticide resistance in Bemisia tabaci (Homoptera: Aleyrodidae) populations from Crete.
The resistance levels to alpha-cypermethrin, bifenthrin, pirimiphos-methyl, endosulfan and imidacloprid were determined in Bemisia tabaci (Gennadius) from Crete. Five B tabaci populations collected from greenhouse and outdoor crops were bioassayed and compared with a reference susceptible strain. Bemisia tabaci collected in a floriculture greenhouse exhibited the highest resistance against all ...
متن کاملAcylsucrose-Producing Tomato Plants Forces Bemisia tabaci to Shift Its Preferred Settling and Feeding Site
BACKGROUND The whitefly Bemisia tabaci (Genn.) causes dramatic damage to plants by transmitting yield-limiting virus diseases. Previous studies proved that the tomato breeding line ABL 14-8 was resistant to B. tabaci, the vector of tomato yellow leaf curl disease (TYLCD). This resistance is based on the presence of type IV glandular trichomes and acylsucrose production. These trichomes deter se...
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 کاملDetection of tomato leaf curl geminivirus in its vector Bemisia tabaci.
Geminiviruses are single-stranded DNA plant infecting viruses that cause major losses in important crops in tropical and subtropical countries. Tomato leaf curl virus (TLCV) belonging to the genera Begomovirus, is a whitefly-transmitted geminivirus that causes a severe leaf curl disease in tomato (Lycopersicon esculentum). The importance of this disease has prompted a great need for a rapid ide...
