Beauveria bassiana (Ascomycota: Hypocreales) as a management agent for free-living Amblyomma americanum (Acari: Ixodidae) in Ohio.

ABSTRACT

Unfed adult Amblyomma americanum were exposed to the entomopathogenic fungus Beauveria bassiana and placed in the field. Ticks exposed to the fungus experienced higher mortality than those in the control group (P = 0.001). It is recommended that for inclusion in a tick management program, the fungus be applied in the late evening during the months March through June as this is when ticks are most active and conditions suitable for fungal activity occur.
