Technical teams in Santiago del Estero, Argentina, successfully controlled a lobster sleeve outbreak in the Fernández town, using both aerial and terrestrial phytosanitary treatments across over 350 hectares. This outbreak, along with others, was effectively managed through a collaborative effort of provincial and national agencies, producers, and Senasa, with particular challenges due to the sleeves' fragmentation and the ongoing COVID-19 pandemic. Ongoing surveillance and control measures are being implemented across the province, with producers encouraged to report any pest sightings to Senasa to enhance pest management efforts.
