Deleterious Effects of Cotton leaf curl virus on Longevity and Fecundity of Whitefly, Bemisia tabaci (Gennadius)

Efficiency of Bemisia tabaci (Gennadius) populations from different plant-hosts for acquisition and transmission of cotton leaf curl virus

Whitefly (Bemisia tabaci) populations collected from five crop plants, viz brinjal, cotton, potato, tomato, soybean and a weed, Sida sp., and maintained on respective host plants were studied for virus acquisition from diseased cotton plant and its subsequent transmission to healthy cotton plants. The presence of virus in whitefly and diseased plants was established by PCR amplification of CLCu...

Natural enemies of cotton whitefly bemisia tabaci gennadius homoptera aleyrodidae in fars province of iran

Long-term association of tomato yellow leaf curl virus with its whitefly vector Bemisia tabaci: effect on the insect transmission capacity, longevity and fecundity.

The association between tomato yellow leaf curl geminivirus (TYLCV, Israeli isolate) and its insect vector, the whitefly Bemisia tabaci, was investigated. Insects that emerged during a 24 h period were caged with TYLCV-infected plants for a 48 h acquisition access period, then with egg-plants--a TYLCV non-host--for the rest of their lives. While TYLCV DNA was associated with the whiteflies duri...

Replication 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...

Implication of the Whitefly Bemisia tabaci Cyclophilin B Protein in the Transmission of Tomato yellow leaf curl virus

Tomato yellow leaf curl virus (TYLCV) is a single-stranded (ssDNA) begomoviruses that causes severe damage to tomato and several other crops worldwide. TYLCV is exclusively transmitted by the sweetpotato whitefly, Bemisia tabaci in a persistent circulative and propagative manner. Previous studies have shown that the transmission, retention, and circulation of TYLCV in its vector involves intera...
