For this purpose, the Larva Immersion Test was performed. Twice dilutions of both oils were tested from a starting dilution of 40% to 2.5%. There were three repetitions for each concentration and for each oil. The control solution in which these larvae were treated consisted of Tween-20, diluted at 2% in distilled water. The experimental groups were stored in an incubator at 27 ± 1 °C and at 85-90% of relative humidity for 24 hours. The larvae mortality was greater than 55% in all tested groups and reached 100% at the 40% concentration for&nbsp;<em>A. muricata</em>, while the control group had a 0% mortality. The LC<sub>50</sub>&nbsp;and CL<sub>90</sub>&nbsp;obtained were respectively 4.0331% and 10.7594% for&nbsp;<em>A. muricata</em>&nbsp;and 7.0942% and 41.4247% respectively for&nbsp;<em>T. peruviana</em>. These results clearly indicate that these oils all have acaricidal effects on&nbsp;<em>Rhipicephalus (Boophilus) microplus&nbsp;</em>larvae. However,&nbsp;<em>A. muricata</em>&nbsp;oil is the most toxic. It can therefore be used as an effective alternative to control the&nbsp;<em>Rhipicephalus (Boophilus) microplus&nbsp;</em>tick and there is a high probability that it can be used for other ticks affecting cattle and even other ectoparasites in Benin and worldwide, thereby reducing the use of synthetic acaricides which are toxic to the environment and ineffective against this tick.</p>}, number={3}, journal={Scientific Journal of Veterinary Advances}, author={Justin Adinci, Kossi and Akpo, Yao and Tonouhewa, Arétas and Eric Yessinou, Roland and Sessou, Philippe and Yovo, Mahuto and Bienvenu Adehan, Safiou and Adoligbe, Camus and Appolinaire Mensah, Guy and Napoléon Assogba, Marc and Abdou Karim, Issaka Youssao and Farougou, Souaïbou}, year={2017}, month={Mar.}, pages={162-169} }
