Intraspecific variation in calorific content of two phytophagous insects Hieroglyphus banian and Belenois mesentina.
The calorific values of the acridid Hieroglyphus banian and the pierid Belenois mesentina [Anaphaeis aurota] were studied using individuals collected in Haryana, India. Various developmental stages reared from eggs of H. banian laid on Desmostachya bipinnata in the laboratory and eggs of A. aurota laid on Capparis decidua in the field were used for the determinations. There was a gradual increase in calorific content of successive instars in both species, which was attributed to a greater deposition of body tissue with an increase in body size. The calorific content of the young adult of H. banian was slightly less than that of the pupa. Females of H. banian had higher calorific values than males.
