Retama Raetam's In-Vitro Acaricidal Action on The Hyalommaaegyptium Tick, Infecting Testudo Graeca Turtles in The Southern Algeria District of Laghouat

This research develops the narrative on investigating the efficacy of the plant extracts of Retama raetam that is essential in treating the tick, Hyalommaaegyptium, developing in Testudo graeca. These Tortoise species lives in the Laghouat region of Southern Algeria.Various extracting solvents are used to extract the essential components of the Retama raetam plant. The Hyalommaaegyptium tick is a member of the species of tortoises, which pose a risk to other animals' existence, particularly that of turtles. Solvents, including methanol, ethanol, and acetone, extract the retama raetam plant. These extracts examine the plant extract to treatHyalommaaegyptium ticks. Ethanol-based Retama raetam plant extract has the highest efficacy. 100% of the ticks die after being exposed for 15 days. The mortality rate of acetone is 33%, while methanol has a 42% mortality rate. Medium lethal concentration tests (LC50) determined the extract concentration, which required the death of 50% of Hyalommaaegyptium ticks. Plant extracts based on ethanol tests have a concentration of 70 mg/ml, methanol; LC50 tests have an 80 mg/ml concentration, and acetone; LC50 tests have a 95 mg/mL concentration. These ticks can be effectively treated using ethanol-based plant extracts, which is crucial for animals' well-being and survival.
