A harmful bee, nicknamed the 'gal bee' or 'killer bee', has been spotted in the Sinop province of Turkey, posing a threat to chestnut trees. First detected in the Marmara Region in 2014 and spread through the sale of chestnut saplings, this bee, originally from China, has prompted concerns among villagers and honey producers. Despite quarantine measures, the bee has spread from Düzce to Bartın, Kastamonu, and now Sinop. The Sinop Provincial Directorate of Agriculture and Forestry has confirmed the pest's presence and is investigating its spread, believing it may have been transmitted by flight rather than through the movement of saplings.
