Özet
Grape is an important fruit consumed both fresh and dried in human nutrition. However, grapes are an important export product for the Turkish economy. There are many harmful insect and disease factors in terms of plant protection in vineyards. The main harmful insect species that affects the yield and quality negatively by feeding on flowers and clusters in vineyards is European Grapevine Moth [Lobesia botrana Denis & Schiffermuller (Lepidoptera: Tortricidae)]. This study was carried out by using sexual attractive traps in two vineyards of 10 decares each between the years 2021-2022 in Diyarbakir Province Hazro District, where the mazruni grape variety is grown intensively. It was aimed to determine the first emergence time, adult population change, the period of active presence in nature, the number of progeny and the infestation rate of the clusters in the vineyards of the cluster moth, which is the main pest in the vineyards. As a result of the study, it was determined that the adult flights of L. botrana were first detected in the traps on 18 April, ended on 21 November, and they were active in nature for about 8 months. A total of 296 adults/traps were counted in the Hurriyet neighborhood in 2021, the maximum weekly population density was 21 October (21 adults/traps), and a total of 1844 adults/traps were counted in Yazgi neighborhood, and the maximum weekly population density was 8 July (198 adults/traps).) was detected on in 2022, a total of 663 adults/traps were counted in Hurriyet neighborhood, the maximum weekly population density was 27 June (80 adults/trap), and a total of 2055 adults/traps were counted in Yazgi neighborhood, and the maximum weekly population density was 20 June (233 adults/traps). trap) was detected. Depending on the population density, it has been determined that the pest creates 4 peaks per year, three before harvest and one after harvest, and can give an estimated 4 generations under natural conditions. In the vineyard in Hurriyet neighborhood, the rate of pest and infestation of the clusters was determined to be 5% and 23%, respectively, and in the vineyard in Yazgi neighborhood, the ratio of L. botrana to the pest and infestation was 25% and 45%, respectively.
