The succinic dehydrogenase activity of eptocephalus dichotomus Baird

Summary The succinic dehydrogenase activity in Streptocephalus dichotomus in the entire animals as well as in the different regions of the body, increased with increase in temperature up to 30°C and at 33°C it decreased.In both males and females there exists a linear relationship between body weight and enzyme activity.Analyses of covariance revealed that the F ratios are not significant in the case of rate of succinic dehydrogenase activity between the two sexes or when the comparison is made within the sexes at the different temperatures.The succinic dehydrogenase activity in the thoracic region is higher than in the head and abdominal regions.This work formed a part of a thesis submitted for the Degree of Doctor of Phylosophy to the University of Madras in 1970.
