Silkworm was infected with Bacillus thuringiensis then treated with  three concentrations (0.5, 0.75 and 1%) of three specific oils (citrus specific Orange, chamomile and Lavander)  to determine their ability as antioxidants and anti-bacterial for recovering the damage occurred in silkworm heamolymph through evaluating some biochemical changes in Lipid peroxidation (MDA) , Protein Carbonyl Contents (PCC) as a biomarker of damage happened in Lipids and protein, also Alanin Transaminases(ALT) , Aspartate transaminases (AST)  and antioxidant capacity. The results showed that (0.5 and 0.75%) of citrus oil was the most effective oil, followed by (1% and 0.75%) chamomile oil which recorded the least damage for PCC and MDA, respectively and highly antioxidant capacity however (0.5% , 0.75%)  citrus oil recoded the least value in (ALT) and (AST) of the two concentrations compared with other oils and control.
