Abstract
This present study shows the potential of five different essential oils Citronella oil, Ylangylang oil, Clove oil, Lemon Grass oil and Thyme oil, showed biochemical activities against Muscadomestica larvae. Newly hatched 2nd instar larvae were collected from the mass culture maintained under the laboratory condition. The larval bioassay was evaluated by using dipping method Protein estimation was determined according to Modified Lowry's method. The total lipids were estimated by Knight et al. (1972) method. DNSA Method was used to determined amylase activity. In the present investigation the total protein, lipid and amylase contents levels are higher in 3% concentration when compared with that of 1% and 2% concentration of each essential oils. The total protein, lipid and amylase in the supernatant homogenated 2nd larval instar of M. domestica larvae was highly decreased as compared to control groups at all different concentrations. These changes indicate that various biochemicals specific changes occur at different concentration. The present findings seem promising and therefore suggest that the usage of essential oils are more effective to reduce the protein, lipid content and amylase activity in 3% concentration.
