Pest and beneficial complex in organic viticulture at the conditions of Gokceada Island
1 Plant Protection Research Station, Genclik Caddesi No. 6, Bornova, Izmir, Turkey
2 Viticulture Research Station, Tekirdag, Turkey
Population densities of harmful and predatory insects have been compared in six table (Trakya İlkeren, Alphonse Lavallée, Tekirdağ Çekirdeksizi, Cardinal, Italia, Amasya beyazı x 28/259-1) and six wine (Cabernet Sauvignon, Merlot, Syrah, Kalabaki, Sauvignon Blanc, Özer Karası) grape varieties in Gokceada between 2008 and 2011. No difference was determined among table grape varieties. Trakya llkeren has been the most suitable grape variety for Gokceada as it is rarely infested by the pests. Population density of Colomerus vitis Pgst. was statistically different in wine varieties in 2010. Cabernet Sauvignon has continuously been infested by the pest. Arboridia adanae Dlabola and Thrips spp. were harmful in Cabernet Sauvignon in 2011. Merlot has been infested with higher populations of insect pests in some years. Hence, Cabernet Sauvignon and Merlot should not be preferred in Gokceada. Kalabaki had the lowest population density. Effect of four combinations of green manure, farm manure and olive cake compost was observed on the population density of harmful and beneficial insects on Trakya Ilkeren and Cabernet Sauvignon. The combinations tested had no important effect on the population density of insect pests and predators. Organic fertilization program should be selected according to what grape and vine tree need.
