The Effect of Trellis System on Some Performances of Lobesia botrana Den. Schiff. (Lepidoptera: Tortricidae)

16265

The present study was conducted in the sub-station of the Manisa Viticulture Research Institute in Alasehir district (38º 34 15 N, 28º 66 54 E) in 2009 and 2010. The study aimed to explore impacts of different trellis systems on some vital activities such as oviposition and feeding of Lobesia botrana Den. Schiff. (Lepidoptera: Tortricidae). The experiment was carried out in four replications. The experiment area was arranged according to randomized complete block design on four different trellis systems, including U-shaped, V-shaped, cordon and pergola trellis system, beinga natural population of Lobesia botrana. The experiment area was composed of four blocks, each of which had one row of every trellis system with a total of 16 rows. The study counted eggs, larvae and pupae of the pest in five clusters from each of the 12 vines per row in weekly intervals. The eggs, larvae and pupae of the pest in clusters were counted by observing during experiment. As a result of the study, trellis systems had impacted on egg-laying preference of females with larval survival indicating an inherent parallel tendency. The most and the least trellis systems preferred by the pest were pergola trellis system (5.0 eggs, 3.1 larvae) and U-shaped trellis system (2.8 eggs, 1.2 larvae), respectively. Using less-or non-preferred trellis systems by the pest considering the location of the vineyard and cultivar features will cause a decrease in the population level of larvae and pupae. Thus, population level of fertile adult with high fecundity will further decrease. Therefore, control against the pest in accordance with integrated pest management will have been begun yet at the stage of setting up facilities. This too will have an important role in the control of the pest.
