Effect of mercury on carbohydrate metabolism of sphaerodema rusticum (heteroptera: belastomatidae)

In the present study Sphaerodema rusticum were exposed to sublethal concentration of mercury. The key enzymes of the anaerobic glucose metabolism (Succinate dehydrogenase ,and Lactate dehydrogenase) activity were observed in testis and seminal vesicle of Sphaerodema rusticum . During the Sublethal concentration of mercury contamination, the Succinate dehydrogenase (SDH) and Lactate dehydrogenase (LDH) were altered. The present study showed that these changes suggest that the activity of enzymes is modified by a change in ambient water. The overall reduction in the glycolytic enzyme activities of mercury -exposed insect seems to reduce energy availability via glucose metabolism, thereby contributing to enhance mercury toxic effects in Sphaerodema rusticum
