7. SUMMARY Fatih DA?LI (M.S. Thesis) t Resistan.ce levels, potential and stability to dicofol and tedion vere investigated in populations of T. cinn&b&rinus j collected f rom greenhouses in Antalya, Kumluca, Demre, Serik, Manavgat, Aksu, Gazipaşa, Alanya and from cotton in Serik and Manavgat. Responses of T. cinn&b&rinus populations to dicofol and tedion vere measured vi th leaf residue and direct exposure assays (using a Potter Spray-Tover), and then LC50 and LC95 vere calculated. Resistance levels vere determined by dividing the LC50 and LC95 value of each population to LC50 and LC95 value of susceptible populations treated vi th the same doses in laboratory. According to leaf residue assay vith dicofol in females obtained from greenhouses in indicated localities resistance detected, as folds of the susceptibles at LC50 and LC95, respectively, vas 58.2-58.9 in Topçular,18.6-15.4 in Kumlucal, 18.1-7.2 in Kumluca2, 7.4-10.2 in Demrel, 9.3-5.0 in Demre2,43.2-24.8 in Serik,2.6-9.l in Manavgat, 2.2-8.4 in Aksu,13.2-6.2 in Gazipaşa and 57.9-41.7 in Alanya. These values vere 4.0-6.4 and 1.3-1.5 folds in females from cotton grovn in Serik and Manavgat, respectively.In direct exposure assays with dicofol in females from greenhouses in indicated localities resistance levels, as fold of the susceptibles at LC50 and LC95, respectively, were 11.4-17.5 in Topçular, 3.5-2.6 in Kum 1 uca 1, 10.6-5.0 in Kumluca2, 3.3-3.9 in Demrel, 5.5-7.2 Demre2, 10.6-15.8 in Serik, 2.5-8.0 in Manavgat, 4.5-15.8 in Aksu, 25.9-23.9 in Alanya and 7.0-4.3 in Gazipaşa. These values were 2.9-3.3, 1.3-1.2 folds in Serik and Manavgat, respectively. According- to direct exposure assays with tedion in eggs of populations from greenhouses in indicated localities: resistance, as folds of the susceptibles at LG50 and LC95, respectively, ' 2.0-1.6 in Topçular, 4.3-4.9 in Kumlucal, 1.7- 2.3 in Kumluca2, 1.2-4.7 in Demrel, 2.0-20.0 inDemre2, 8.9- 75.9 in Serik, 2.1-1.7 in Manavgat, 10.4-1.4 in Aksu, 7.0- 49.0 in Alanya 6.6-27.5 in Gazipaşa. These values were 3.0- 1.9, 3.7-12.0 folds in Serik and Manavgat, respectively. T, cinnabarinus has a potential to develop resistance to both dicofol and tedion. The resistance level increased to 100 folds (LC50) in T. cinnabar inus populations which were treated with dicofol 16 times in nearly 7 months' period. Resistance to tedion was 50 folds (LC95) in another T. cinnabarinus population which was treated alternatively with dicofol and tedion (each applied 6 and 8 times, respectively). Five months after the selection ceased, resistance level decreased from 100 only to 99 folds (LC50) in populations selected using only dicofol. In another selected population using tedion and dicofol, resistance to tedion decreased from 50 to 2 fold (LC95). These results suggest that the resistance to dicofol was relatively stable for the period tested. The resistance to tedion was, however, shown to decrease significantly in 5 months. Because of instability of tedion resistance, tedion can be used after some time in areas where resistance to tedion already exists. 57
