Abstract:

Black shading nets are commonly used to protect agricultural crops from excessive solar radiation, wind, and for water saving. Recent studies have demonstrated that when black nets were replaced by either red, yellow, or pearl nets (ChromatiNets®), of equivalent shading capacity, it increased the tomatoes fruit yield and improved their quality. Ben-Yakir and co-workers studied the effects of colored shading nets on the infestation by the sweet potato whiteflies (Bemisia tabaci) and the incidence of the viral diseases transmitted by these insects. These studies were conducted in the semi-arid Besor region in southern Israel. Colored nets with 30-35% shading capacity were used. Whiteflies landed 40 times more often on the yellow shading net compared to the black or red nets. Although these shading nets permit free passage of whiteflies, the infestation levels of plants in boxes and tunnels covered by the yellow net were consistently 2-3 folds lower than in the same structures covered by the black or red nets. The incidences of the whitefly-borne tomato yellow leaf curl virus (TYLCV) in tomato plants grown under the black nets ranged between 15-50%. However, the disease rates in tomato plants grown under the yellow net were 2-4 folds lower than under the black or red nets. We propose that an arresting response of the whiteflies to the yellow net is responsible for the protection achieved.
