ABSTRACT
In this study, an alternative control method was developed for camel tick (Hyalomma dromedarii Koch) and cattle tick (Hyalomma impeltatum Schulze & Schlottke), to replace the widely used traditional acaricides. Huwa-San TR50 is a formulation of hydrogen peroxide, stabilized by the addition of a small quantity of silver and is extensively used as a disinfectant. Both tick species were susceptible to certain concentrations of Huwa-San TR50: 4,000, 8,000, 10,000, 12,000 and 14,000 ppm. A marked reduction in the movement of both tick species was observed 24h of applying Huwa-San TR50, at 10,000 ppm and above. This study recorded an increase in percentage mortality with increasing concentrations of Huwa-San TR50 and this resulted in mortalities of 66.5% for H. dromedarii and 76.5% for H. impeltatum after 24 h of direct exposure (direct spray treatment) whereas in the dipping treatment, the mortality was 60% and 70% for H. dromedarii and H. impeltatum at 14,000 ppm of Huwa-San TR50. Huwa-San TR50 was found to be moderately effective in killing both tick species. Therefore, it can be used to develop a new and safe strategy for controlling ticks, so as to produce dairy and meat products with minimal residual contamination.
