“…Among monopartite begomoviruses, TYLCD‐associated viruses (Navas‐Castillo et al ., ) are excellent candidates for investigating aspects related to begomovirus–plant–vector interactions, due to the large and interesting amount of biological information available for them. This includes virus species and strains that differ in their host range/induction of symptoms (Navas‐Castillo et al ., ; Monci et al ., ), or the ability to confront resistance genes (García‐Andrés et al ., ; Tomás et al ., ). The present investigation demonstrated that A. thaliana was a suitable host to support local replication and systemic accumulation of TYLCV by using A. tumefaciens ‐mediated inoculation.…”

Tomato yellow leaf curl disease is one of the most devastating viral diseases affecting tomato crops worldwide. This disease is caused by several begomoviruses (genus Begomovirus, family Geminiviridae), such as Tomato yellow leaf curl virus (TYLCV), that are transmitted in nature by the whitefly vector Bemisia tabaci. An efficient control of this vector‐transmitted disease requires a thorough knowledge of the plant–virus–vector triple interaction. The possibility of using Arabidopsis thaliana as an experimental host would provide the opportunity to use a wide variety of genetic resources and tools to understand interactions that are not feasible in agronomically important hosts. In this study, it is demonstrated that isolates of two strains (Israel, IL and Mild, Mld) of TYLCV can replicate and systemically infect A. thaliana ecotype Columbia plants either by Agrobacterium tumefaciens‐mediated inoculation or through the natural vector Bemisia tabaci. The virus can also be acquired from A. thaliana‐infected plants by B. tabaci and transmitted to either A. thaliana or tomato plants. Therefore, A. thaliana is a suitable host for TYLCV–insect vector–plant host interaction studies. Interestingly, an isolate of the Spain (ES) strain of a related begomovirus, Tomato yellow leaf curl Sardinia virus (TYLCSV‐ES), is unable to infect this ecotype of A. thaliana efficiently. Using infectious chimeric viral clones between TYLCV‐Mld and TYLCSV‐ES, candidate viral factors involved in an efficient infection of A. thaliana were identified.

“…In most cases, the transgenic plants were tested under laboratory conditions, making it hard to predict how these plants will perform under field conditions. It can also be anticipated that the exposure of resistant transgenic plants to natural virus populations in the open field, will initiate an evolutionary process in the virus population through mutation and recombination events and the formation of new virus strains that may threaten resistance stability (Garcia-Andres et al 2009). …”

This review presents and discusses the merits of the methodologies available for implementing integrated pest management (IPM) of B. tabaci populations: namely, chemical control with selective insecticides, biological control, crop plant resistance and physical/mechanical methods. Insecticides, by their poisonous nature, are often harmful to natural enemies and therefore, disruptive to overall pest management. However, the more modern materials that are effective for B. tabaci control are relatively specific to the target pests, and therefore are less harmful to natural enemies and the environment; consequently, they are also more suitable for integrative combination with other methods. Natural enemies, by themselves, usually do not form a suitable solution of B. tabaci-caused problems. However, their occurrence and use greatly reduces the pest's populations. Since viral plant diseases transmitted by B. tabaci are not curable, the principal tactics for their management should be based on prevention of transmission by physical-mechanical methods and/or on utilization of host-plant resistance. The correct implementation of natural enemies will help to reduce whitefly numbers, which can then be more readily managed using cultural and, only if necessary, chemical countermeasures.

Viral diseases are a serious limitation to the tomato crop in the region of Vale`ncia, Spain. A survey of tomato viruses in open field cultivation plots was made in the three provinces of this region. A total of 228 plots classified according to the origin of the seed (farmer seed plots or commercial seed plots) were surveyed, from which 1300 individual plants were sampled and tested for Cucumber mosaic virus (CMV), Pepino mosaic virus (PepMV), Parietaria mottle virus (PMoV), Potato virus Y (PVY), Tomato mosaic virus (ToMV), Tomato spotted wilt virus (TSWV) and for the tomato yellow leaf curl disease (TYLCD). Virus infection was detected in 58.9% of the plants sampled and in 86.0% of the plots surveyed. All these viruses were detected, and the most prevalent were ToMV and PVY (34.1% and 27.1% of infected plants, respectively), but PMoV and TYLCD were the less prevalent (1.2% and 1.3% of infected plants, respectively). Differences among provinces and seed origin were found for most of the viruses studied. In particular, both ToMV and PVY had a higher level of infection in plants from farmer seed plots than in commercial seed plots, which accounts for the higher percentage of virus-infected plants in the former (64.2%) when compared to the latter (49.1%). Single and multiple infections were found in 42.38% and 16.54% of the samples, respectively. The most common multiple infection was of ToMV, PVY or both. These results show that the percentage of infected plants and plots in open field cultivation is very high in this region and the origin of the seed is an important factor in the incidence of virus infection. In this respect, preventive measures, including virus-free seed, resistant cultivars and improved cultural practices, could reduce the incidence of virus infection.
