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...

Tomato is one of the most important vegetables in world. Presence diseases and pests growing area significantly affect choice variety tomato. Early-stage diagnosis plays an role determining whether tomato subject to effective economical chemical, mechanical biological controls, internal external quarantine. In this study, deep learning was used diagnose some tomatoes. For purpose, a novel CNN-b...

ABSTRACT The effect that Tomato yellow leaf curl virus (TYLCV)-infected resistant tomato plants may have on virus epidemiology was studied. Four tomato genotypes that exhibit different levels of viral resistance, ranging from fully susceptible to highly resistant, served as TYLCV-infected source plants. Viral acquisition and transmission rates by white-flies following feeding on the different s...

Yellow leaf curl disease caused by begomoviruses has emerged as a major limitation to the production of eggplant (Solanum melongena) in several regions world. Tomato yellow Kanchanaburi virus (TYLCKaV) is bipartite begomovirus isolated from diseased areas Indochinese peninsula, South China, and Maritime Southeast Asia. In this study, five species Indonesia, including TYLCKaV, were inoculated us...

The Middle East is a major producer of both processing and fresh market tomatoes (Solanum lycopersicum); and tomatoes are a main component of the local cuisines. Since Tomato yellow leaf curl disease was first reported in Israel in the early 1950s, it has become one of the major, if not the most important, constraint to production (see historical perspective in Part I, Chapter 1). This disease ...

A variety of fresh market vegetables, including watermelon and tomato are economically important crops in Florida. Whitefly-transmitted Squash vein yellowing virus (SqVYV) was first identified in squash and watermelon in Florida in 2005 and shown to cause a severe decline of watermelon vines as crops approach harvest. Florida is most economically impacted by SqVYV, although the virus has been d...

The complete sequence of 9871 nucleotides (nts) of parsnip yellow fleck virus (PYFV; isolate P-121) was determined from cDNA clones and by direct sequencing of viral RNA. The RNA contains a large open reading frame between nts 279 and 9362 which encodes a polyprotein of 3027 amino acids with a calculated M(r) of 336212 (336K). A PYFV polyclonal antiserum reacted with the proteins expressed from...

Greenhouse studies using a randomized complete block design were carried out to evaluate the effect of six insecticides on transmission of Tomato yellow leaf curl virus (TYLCV) by the silverleaf whitefly, Bemisia tabaci biotype B Gennadius (Hemiptera: Aleyrodidae) to tomato, Lycopersicon esculentum (Miller) (Solanales: Solanaceae), seedlings that were inoculated with whiteflies from a TYLCV col...
