# Turkey continues brown marmorated stink bug control > Live situation record from CLSTR: https://clstr.news/situations/turkey-brown-stink-bug-control > Updated: 2026-08-04T09:24:24.000Z. Sources: 32. Developments: 10. Turkey’s integrated pest‑management programme against the brown marmorated stink bug, launched in 2025, has been expanded to 40 provinces. By early August 2026 the Ministry of Agriculture and Forestry reported that 1.156 million samurai wasps – described in the statement as Vespa velutina – had already been released, with a target of 1.65 million for the year. The effort combines these parasitoids with winter‑site control actions in 859,329 households, distribution of pheromone traps, protective gear and limited chemical treatments for hazelnut growers. International cooperation continues: 20,000 wasps were shipped to Azerbaijan for a joint release, and technical support is being provided for ongoing work in Georgia. Farmer education, informational brochures and two research projects – one on economic‑damage thresholds and another on optimizing chemical‑use limits – are also part of the plan. The wasp releases aim to protect hazelnuts and more than 300 other plant species from the invasive pest. ## Timeline ### 2026-08-04: Turkey releases 1.65 million samurai wasps to combat brown marmorated stink bug Turkey's agriculture minister announced a 2026 release of 1.65 million samurai wasps to fight the brown marmorated stink bug, with 40‑province coverage, farmer training and cooperation with Azerbaijan and Georg 14 sources. https://clstr.news/cluster/turkeys-agriculture-minister-ibrahim-yumakl-warns-of-heightened-forest-fire-risk-in-izmir-region ### 2026-07-06: Giresun releases 130,000 samurai wasps to fight brown stink bug infestation Turkey released 130,000 samurai wasps in Giresun as part of an integrated fight against the brown marmorated stink bug, with annual production of 1.6 million wasps and some sent to Azerbaijan. 4 sources. https://clstr.news/cluster/turkey-releases-130000-samurai-wasps-in-giresun-to-fight-brown-marmorated-stink-bug ### 2026-07-06: Turkey's hazelnut crop faces surge in brown marmorated stink bug threat Turkey's hazelnut growers warn that a surge of brown marmorated stink bugs, compounded by fungal disease and weeds, could slash 2024 yields, prompting calls for coordinated government and farmer action. 5 sources. https://clstr.news/cluster/turkeys-hazelnut-crop-faces-surge-in-brown-marmorated-stink-bug-threat ### 2026-06-25: Turkey releases 1,200 crested quails in Kastamonu for pest control Turkey's Ministry of Agriculture and Forestry released 1,200 crested quails in Kastamonu province as a biological control effort against ticks, with officials and villagers present. 5 sources. https://clstr.news/cluster/turkey-releases-1200-crested-quails-in-kastamonu-for-pest-control ### 2026-06-22: Turkey deploys samuray bees to combat brown marmorated stink bug in hazelnut orchards Turkey is releasing samuray bees to curb brown marmorated stink bugs threatening hazelnut farms, with tens of thousands deployed in Giresun and Trabzon and a national total of 1.5 million. 4 sources. https://clstr.news/cluster/turkey-releases-samurai-bees-to-curb-brown-marmorated-stink-bug-in-hazelnut-orchards ### 2026-06-21: Turkey plans release of 51,000 quail and pheasants for biological pest control Turkey will release 51,000 quail and pheasants in 2026 to fight ticks and stink bugs, covering 62 provinces with three‑year hunting bans on release sites. 10 sources. https://clstr.news/cluster/turkey-releases-51000-quail-and-pheasants-to-combat-ticks-and-brown-hedgehog-beetles ### 2026-06-19: Turkey releases thousands of parasitic wasps to combat brown marmorated stink bug Turkey’s agriculture ministry released over 26,000 parasitic Samuray wasps in Artvin and Bartın to biologically control the invasive brown marmorated stink bug threatening crops. 2 sources. https://clstr.news/cluster/turkey-releases-thousands-of-parasitic-wasps-to-combat-brown-marmorated-stink-bug ### 2026-06-18: Turkey releases 300,000 samurai wasps in Ordu to combat brown marmorated stink bug threatening hazelnut crops Turkey releases 300,000 samurai wasps in Ordu to fight brown marmorated stink bug, while hazelnut growers are cautioned the pest still threatens the upcoming harvest. 2 sources. https://clstr.news/cluster/turkey-releases-300000-samurai-wasps-in-ordu-to-combat-brown-marmorated-stink-bug-threatening-hazeln ### 2026-06-16: Turkey releases 1.65 million samurai bees to combat brown marmorated stink bug in Black Sea farms Turkey’s agriculture ministry will release 1.65 million samurai bees nationwide to curb the brown marmorated stink bug, combining biological control with other pest‑management methods in the Black Sea region. 2 sources. https://clstr.news/cluster/turkey-releases-165-million-samurai-bees-to-combat-brown-marmorated-stink-bug-in-black-sea-farms ### 2026-06-10: Turkey expands hazelnut pest control to curb brown stink bug spread Turkey's Düzce and Samsun Çarşamba regions intensify hazelnut pest control, treating abandoned buildings and issuing alerts as brown stink bug numbers rise with heat. 2 sources. https://clstr.news/cluster/turkey-expands-hazelnut-pest-control-to-curb-brown-stink-bug-spread --- Cite as: Turkey continues brown marmorated stink bug control.
