[Evaluation of the biological control potential of Metarhizium anisopliae toward Boophilus microplus in pen trials].
The aim of the present study was to evaluate the capacity of the fungus Metarhizium anisopliae to control Boophilus microplus tick in pen trials. Infested calves were held in individual pen and treated with fungus suspension through aspersion bath. The results were evaluated based on ticks' mortality rate for 28 days after treatment, and on the analysis of biology of tick's samples which were transferred to an incubation chamber. It was reported 33% of mortality during the total period analyzed, and the production of eggs and nutritional rates were decreased only for a short period after treatment.
