Abstract
This study was conducted with the aim to evaluate efficacy of applying 4 different formulations of Beauveria Bassiana (BB) fungus spore to combat Hyalomma ticks. Formulations used included: 1) Distilled water with 2% Tween and BB; 2) Distilled water with 10% cottonseed oil, 0.01% sucrose, 0.2% tween and BB; 3) Distilled water with 10% liquid paraffin, 0.01% sucrose, 0.2% tween and BB, anddistilled water as the control group. Concentration of 1.76×108 was used in preparing formulations. The four prepared formulations were equally sprayed on 128 engorged mature ticks, in 4 groups. Number of dead tick due to spray of formulations were counted in the following days. Treatment effect on mortality of ticks, was assessed using time-survival analysis. 9 days after spraying different formulations, it was found that formulation containing BB fungus had eliminated 50 to 55% of the ticks. Due to the fatality of 55 percent Hyalomma ticks in this research, it can be hoped that in the future with further research, oil suspension containing BB fungus can be used to combat Hyalomma ticks.
