Changes in Protein Profile in Haemolymph of Bombyx mori Larvae in Response to Aloe vera Essential Oil

The present study was undertaken to evaluate the total protein content in nistari race of multivoltine mulberry silkworm. The experiments were conducted with different amount of Aloe vera essential oil viz. 0.25, 0.50, 0.75 and 1.00 ml with respect to the single, double and triple treatment of Bombyx mori larvae. The maximum level of the total protein content in the haemolymph of Bombyx mori larvae in initial (30.245±0.423 μg/ml) and final (23.023±0.204 μg/ml) was noticed in case of triple treatment with 0.75 ml Aloe vera essential oil. The minimum total protein content in the haemolymph of Bombyx mori larvae in initial (22.217±0.210 μg/ml) and final (15.553±0.280 μg/ml) was recorded in case of triple treatment by 1.00 ml Aloe vera essential oil. Since protein is major and chief constituents of silk thus, the treatment of larvae with Aloe vera essential oil may be boon for sericulture industries to increase the production of silk and cocoon character at commercial scale.
