The first record of economic pest on Tunceli Mountain Garlic (Allium tuncelianum): Garlic moth Dyspessa ulula (Borkhausen, 1790) (Lepidoptera: Cossidae)

Abstract : This study was conducted in Ovacık district of Tunceli province between 2021-2023. During the surveys carried out to determine the pests and diseases causing economic loss in the plantation planted on 50 decares of land in Ovacık district in order to popularise Tunceli garlic (Allium tuncelianum), Dyspessa ulula (Borkhausen, 1790) (Lepidoptera: Cossidae), which is a problem in Turkey and in the world from time to time in cultivated garlic plantations, was encountered for the first time in Tunceli mountain garlic. In order to determine the damage status of the species, the number of damaged teeth (single onion) in 1000 garlic bulbs taken randomly at harvest time (2021, 2022, 2023) was calculated and it was determined that the damage rate was 15% in 2021, 35% in 2022 and 48% in 2023. Pest larvae belonging to different larval stages were found in garlic bulbs at a rate ranging from 2-10. It is thought that if the pest is not combated, the contamination and damage of the species will increase and it will threaten the endemic Tunceli garlic, which is an important product for the region and our country, economically. When the product losses are evaluated as of 2023; it is seen that a 100 kg harvest at a price of 500 TL (170 USD) per kg corresponds to a foreign currency loss of 170 USDx48=8160 USD. It is understood from the losses over the years that this loss will continue to increase in the following years.
