“…Extracts of many Solanum species were also reported to have high biocidal effects against B. microplus larvae (Rosado-Aguilar et al, 2010). Moreover, Aloe yavellana latex was report to be very effective against Amblyomma variegatum tick larvae (Hailesillassie et al, 2018). Choudhury (2009) reported that 20 to 100% neem seed oil results in 100% mortality of B. decoloratus larvae in 24 to 27 hrs.…”

Livestock tick infestation and tick-borne diseases cause significant loss in the livestock sector. This problem is especially severe for livestock owners in developing countries who have limited or no access to modern veterinary information and services. Therefore, the use of medicinal plant-based formulations is better alternatives for tick control. Solanum incanum L. is one of the medicinal plants used against livestock tick infestation in Ethiopia. However, limited efforts were made to investigate the larvicidal effects of extracts of the plant against the larvae of the most common tick species. This study reports the larvicidal effects of crude aqueous extracts of the aboveground parts of S. incanum L. against Boophilus decoloratus. Fruit, leaf, and stem extracts were effective in killing B. decoloratus larvae at 5%, 10%, 20%, and 40% (w/v) concentration after 24 and 48 hrs of treatment. Fruit crude aqueous extract at 40% (w/v) concentration resulted in the highest mortality rate after 24 (92.0 ± 6.3) and 48 hours (97.6 ± 2.1) (p ≤ 0.05). The larvicidal effects of crude leaf extract (at 20 and 40% (w/v)) were also high. The fact that leaf crude ABOUT THE AUTHOR
