Effects of monoterpenes on digestive enzymatic activities and some constituents involved in intermediary metabolism of (Everts) (Coleoptera: Dermestidae).

Our study aims to evaluate the repellency and fumigant toxicity profiles of 3 essential oil components (EOCs) namely Limonene, Menthol and Linalool against last instar larvae. Limonene is the most toxic chemical tested. Various parameters are examined, including digestive enzymes, enzymes of intermediary metabolism (alanine aminotransferase (ALT), alkaline phosphatase (ALP) and aspartate transaminase (AST)), and oxidative stress biomarker (esterase).
