“…Polyhouses are used extensively in Mediterranean countries and are frequently associated with reports of begomovirus disease problems. Screen nets on windows and doors were reported to be effective in reducing incidence of TYLCV but, additionally, weekly insecticide treatments for the first 6 weeks may have had an effect (Arsenio et al , 2002). Similarly, in spite of the fact that screens limited the entry of B. tabaci , numerous insecticide treatments were also required (Polizzi & Asero, 1994).…”

1 In two experiments carried out in Guadeloupe, barriers were used to reduce the entry of the virus vector Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) to tomato plots. The barriers erected around the crop were of insect-proof cloth fences (<50 mesh), 1.5 m in height, in the first experiment with a deltamethrintreated, insect-attracting strip facing inwards, and, in the second, with the barrier but no insecticide-treated strip. 2 A mathematical model of epidemic development was fitted to the symptom data from the treated and control (unprotected) tomato plots. There were two viruses present, tomato yellow leaf curl and potato yellow mosaic; specific detection confirmed that symptoms gave an accurate indication of infection and that the two virus diseases had similar progress curves. 3 Parameter estimates obtained by model-fitting suggested that the barriers reduced vector immigration by approximately 12-fold but that B. tabaci retention within the plots was also increased slightly despite the mortality caused by the insecticide-treated strips. Disease establishment was delayed by approximately 2 weeks. The results obtained in the second experiment involving barriers deployed without insecticide-treated strips could be explained by a large increase in B. tabaci retention within the barriers resulting in more rapid virus disease progress than in controls. The results of mathematical modelling indicate that partial insect barriers can be worse than none because sufficient whiteflies can enter to establish a population and, at the same time, large numbers are retained in the barrier plot, with the net effect being a more rapid population increase than in the absence of barriers.

“…TYLCV can be controlled by eliminating or reducing the initial source of inoculum through uprooting diseased plants. Berlinger et al (2002) proposed that physical barriers are most common and popular approach being experienced for protection of tomatoes in the Mediterranean from 1990 and other regions (Arsénio et al, 2002). Antignus et al (2001) narrated that another approach practiced in protected culture is Ultraviolet absorbing plastic films have presented good results.…”

The tomato crop is affected by various biotic and abiotic factors. Among the biotic factors, Tomato Leaf Curl Virus (TLCV) is one of the most devastating viruses of tomato. The virus belongs to Begomovirus and family Gemniniviridae. The genome of virus is single-stranded-DNA. It is naturally transmitted through whitefly (Bemisia tabaci). The virus is responsible for causing severe economic losses up to 80% in tomato crop-growing regions and continuously threatening the tomato crops. The increasing severity of TLCV has compelled plant virologists to develop accurate detection and identification of the virus. TLCV is responsible for certain biochemical changes and considerably affecting the plant growth. Tomato Leaf Curl Virus is significantly influenced physiological parameters and metabolic activities of all tomato varieties. The biochemical changes of cellular components are caused due to morphological deviation of infected virus plants, and symptoms expressed by the plants can determine the magnitude of the vegetable losses. It is evident from the previous reports, that nutrients were effective in reducing TLCV from a tomato plant. Moreover, the usage of resistant varieties and controlling of whitefly population and management of TLCV by different nutrients are some of the economical and recommendable ways to manage TLCV. Among the organic management strategies, the compost is also considered best in suppressing disease severity. Moreover, epidemiology plays a vital role in the spread and progress of the disease. Keeping in view the importance of TLCV and its effects on tomato crop, the present review will highlight the etiology, physiology and management of TLCV.
