Abstract

This study aimed to evaluate the bioactivity of some active ingredients of plant extracts , menthol, camphor and their combination, on the adults of clover land snail, Monacha obstructa (Montagu) by two methods of application, leaf dipping method and contact method (thin layer film). Also, sub-lethal concentration (¼ LC50) of the combination using the contact method (thin layer film) was used to measure some biochemical parameters as alanine amino transaminase (ALT), aspartate amino transaminase (AST), alkaline phosphatase (ALP) and acid phosphatase (ACP). The results revealed that, the combination of camphor and menthol was more effective than each ingredient alone, by the two application methods, with LC50 11757.11 and 8907.73, respectively. However, the results of all biochemical parameters, (ALT, AST, ALP & ACP) for the tested samples were significantly different from control.
