The present work is carried out to observe the biochemical effect of Malathion on the glucose, glycogen and protein levels in the larvae of rice moth. The objective was to examine the changes in carbohydrate (glucose & glycogen) and protein contents. The larvae were released on treated as well as normal dietary medium. After 24hrs 50% mortality was found at 8ppm dose level. Then 1/5th of LC50 concentration were mixed with dietary medium and allowed larvae to feed for 168hrs, the surviving larvae were taken for estimation of glucose, glycogen and protein. The result shows carbohydrate contents (glucose & glycogen) were found to be normal in the larvae fed on normal diet while pesticidal treatment caused an overall decrease where as the protein content has been found to be increased after pesticidal treatment. Later on all remaining larvae were transferred to normal dietary medium, after 168hrs the recovery changes were noted.
