Ticks are usually common parasites that disturb and destroy some livestocks of sheep, cows and others. That is why, most agricultural and livestock sectors depend on using chemical pesticide or acaricide to terminate these ticks. Most of the pesticidal users are unaware of the impacts of these chemicals to their health and environment if used continually. Ticks maybe able to adapt resistance from these acaricides and may lead to an increase of dosage of chemicals same as its price. Finding a

This study was conducted to test the biocontrol agent of the available fungi in the Department of Agriculture-General Santos City, against the increasing number of cow ticks, Rhipicepalus microplus within the study area. Two fungi were used in the treatment, the Trichoderma viride and Metarhizium anisopliae. The three stages of ticks were treated with these fungi in direct application using suspension method. The treated ticks were then placed to their designated Petri dishes. Significant results and observations were then recorded and total number of dead specimens was counted. Graphical representation and statistical analysis using PAST and Microsoft Excel software were provided for better and simplified discussion of the result. It was shown that M. anisopliae exhibits a higher effectivity compared to the T. viride in killing cows ticks. This fungus can be an alternative pesticide against the said parasite.
