Research on Feeding Dynamics and Ecological-Economic Control of Lobesia botrana ([Denis & Schiffermüller, 1775]) (Lepidoptera: Tortricidae) Species

Abstract

Lobesia botrana ([Denis & Schiffermüller, 1775 (Lepidoptera: Tortricidae) species is commonly called “Grass Moth”. Although its main host is grapevine; L. botrana is a polyphagous species that also meets its nutritional needs with plants such as laurel, jujube, blackberry. This study, which is based on the determination and control process of the feeding dynamics of L. botrana; was carried out in two different vineyard areas where Emir and Parmak grape varieties were located in 2021-2022. Delta type traps were used to follow the biological process of the taxon. The traps were hung on the vines determined before the flowering period and after the temperature reached 12 degrees. The study was carried out in thermohygrographic values were taken from the observation trench in the vineyard area and these values were compared with the phenological values of the grapevine. As a result, it was seen that the nutrition and economic-ecological control of L. botrana are directly related to plant phenology and ecology. Here, it was also determined that the control process of the species varies according to the years and that grapes, which are considered as the main food of L. botrana, are effective on the development and density of the moth in the context of changes in plant biology caused by ecological factors such as temperature, disease and precipitation during the year.
