Effect of magnetic field on some biological and physiological aspects of the glassy clover snail Monacha cartusiana (Stylommatophora: Hygromiidae)‎

الملخص EN

The present work was carried out to investigate the effect of magnetic field (MF) on the biological and physiological responses of Monacha cartusiana (Müller) (Stylommatophora: Hygromiidae) and land snail one of the serious agricultural pests in Egypt.

Snails exposed to magnetic field (5 similar magnet piece each one with a magnetic power 18 milli– tesla).The obtained results showed reduction in the percentage of egg hatchability (fertility) which recorded 62.16% for magnetic field and 91.01% for control groups and mean incubation period of M.

cartusiana eggs for magnetic field was (35.5 days) compared to control (23.5 days).

Also, result showed that magnetic field caused significant increase in the activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the hemolymph of tested land snail.

While, exhibited significant decrease in the activity of alkaline phosphatase (ALP), acid phosphatase (ACP) and Lactate oxidase (LO) enzymes.

On the other hand, the levels of total protein, total lipid and cholesterol content were significant decrease after exposure M.

cartusiana to magnetic field.
