The longhorned tick, Haemaphysalis longicornis, is one of the vectors of severe fever with thrombocytopenia syndrome virus (SFTSV) in human. The use of pyrethroid insecticides induced pest resistance and environmental residual toxicity. Here in this work, our interest was given to the selection of highly virulent fungi against longhorned tick. A total of 101 fungal pathogens were assayed by dipping the nymph stage of ticks into a conidial suspension. Interestingly of the several species, one species showed high virulence and mycosis were observed in 7-15 days. Highly virulent strains were selected, and semi-field experiments were conducted. As a result, the control efficacy of the isolate was over 80% at 30 days of treatment. This work suggests that entomopathogenic fungi could be used to effectively control longhorend ticks.
