The III International Workshop on Innovative Technologies for Ectoparasite Control – 2026, organized by the Universidade Federal de Goiás (UFG) and the Centro de Excelencia em Saúde Única (CESU), will bring together national and international researchers to discuss advances in entomopathogenic fungi, fungus–arthropod interactions, infection and virulence mechanisms, and innovative biotechnological approaches for biological control. The workshop aims to promote scientific collaboration and knowledge exchange, strengthening the development of sustainable strategies for the management and control of pests and arthropods of agricultural and public health importance.
