摘要

The tropical tasar silkworm, Antheraea mylitta Drury is sericigenous wild insect has own dictation on its life cycle stages. Being a poikilothermic organism, temperature decides the fate of A. mylitta during embryonic and postembryonic development. Silkworm eggs (seed) is very vital input of tasar silk industry but due to global warming elevation in temperature with less humidity during 1st crop grainage of A. mylitta negatively affects the quality and quantity of egg hatching. In the present study, impact of temperature stress on embryonic development and biochemical profile of A. mylitta eggs has been investigated. Data reveals that considerable alteration in temperature used to hamper the protein and carbohydrate profile which leads to affect the embryonic development and hatching of eggs. Fluctuation in temperature with low humidity causes delay in egg hatching and decrease in hatching percentage. But higher temperature with low humidity during embryonic development of eggs resulted in death of embryo during early age. The depressed eggs with fully formed dead larvae inside the eggs were found after high temperature stress. The concentration of the protein and carbohydrate steadily decreases during subsequent larval differentiation until hatching. Protein and carbohydrate profile also confirm the death of embryo during early stage. In un-hatched eggs, due to less metabolized utilization higher concentration of these nutrients are available. Our initial information indicates that protein and carbohydrate profile can be utilized as biochemical marker for testing appropriate embryonic development and hatchability of eggs.
