Abstract :European grapevine moth, Lobesia botrana insert ignore into journalissuearticles values(Denis & Schiffermüller); insert ignore into journalissuearticles values(Lepidoptera: Tortricidae); is the most serious pest of vineyards on a worldwide scale. The study aimed to determine the adult and larval population fluctuations and the generation number for the control of the L. botrana. The present study was conducted in a 1 ha vineyard in Serik district of Antalya province during 2014 and 2015. After the first adult in traps, adult and larval population of pest monitored, weekly. The study findings revealed that L. botrana adults were initially observed in nature in mid-March and remain active for almost eight months in both years. The second peak in the adult count was observed on June 2 and June 12, in 2014 and 2015, respectively. The highest adult density was observed on July 7, 2014 insert ignore into journalissuearticles values(72.5 adults trap-1); and July 14, 2015 insert ignore into journalissuearticles values(54 adults trap-1);); during the third peak. The highest larval count was determined on July 14, 2014 insert ignore into journalissuearticles values(1.72 larva bunch-1); and on July 22, 2015 insert ignore into journalissuearticles values(1.45 larva bunch-1);. The data obtained show that L. botrana gives four full generations in Antalya province conditions. Based on the data, it could be suggested that pest population could partially generate a fifth generation in September. It is recommended to consider the determined second and third peak dates in the pest control strategy in Antalya province.
