Evaluation of Lousicidal Activity of Ziziphus mauritiana Alkaloids and Eucaylptus camaldulensis Terpenoids Leaves Extracts in Chickens: An In Vitro Study

The present study aimed to highlight and assess the in vitro poultry anti-lice properties of Ziziphus mauritiana alkaloids and Eucalyptus camaldulensis terpenoids leaves extracts. In vitro poultry antilouse effects of the extracts of various concentrations (1 mg/mL, 5 mg/mL, and 10 mg/mL) using filter paper contact bioassay was applied. Results revealed that lice mortality was concentration-dependent for both studied extracts. The median lethal concentration (LC50) values were 3.687 and 1.045 for alkaloids and terpenoids extracts respectively. The results indicate that terpenoids extract has strong lousicidal activity. Further steps should be pursued to make these extracts to be tested in vivo then may be used as a novel treatment for poultry lice in future, allowing lice control in a less aggressive way to the environment
