EFFECT OF CARBARYL AND LINDANE ON THE ACTIVITY LEVELS OF SOME SELECTED ENZYMES IN THE MATERNAL AND EMBRYONIC-TISSUES OF THE VIVIPAROUS SCORPION, HETEROMETRUS-FULVIPES (KOCH)

Levels of activity of the enzymes aspartate aminotransferase (AAT), alanine aminotransferse (ALAT) & glutamate dehydrogenase (GDH) in the maternal & embryonic tissues of Heterometrus fulvipes were determined following administation of the first and the second sublethal doses of the pesticides, carbaryl & lindane. The pesticides administered brought an elevation in the activity levels of AAT, ALAT and GDH of maternal tissues after 48 hours which persisted for a period of one month. Lindane exerted a greater effect than carbaryl. The levels of activity in the embryonic tissues were not significantly altered. The results are diseussed in the light of protein metabolism in the maternal and embryonic tissues under the stress of the pesticides.
