Impact of Diseases on the Biochemical Contents of Tropical Tasar Silkworm Antheraea Mylitta D

The present communication accounts for the biochemical variation in percent ; carbohydrate, protein, lipid, moisture and ash contents in relation to different diseases, viz; sporozoasis, bacteriosis, virosis and mycosis of tropical tasar silkworm Antheraea mylitta. The results obtained are indicative of the fact that the estimated biochemical contents at larval, pupal and adult stages are significantly lesser in diseased tasar silkworms in comparison to control (non diseased), during the seed crop (July - Aug ) and commercial crop (Sep - Oct) season. Further the biochemical concentrations are comparatively better in a commercial crop season than the seed crop season. The significant decrease in the percent biochemical contents among the infected stages of tasar silkworm is presumed due to the adverse effects of different pathogens causing different diseases with different mode of actions, since the pathogens have different physio-genetic makeup as they belong to different species with different nature manifestations.
