Abstract
in the present study, the potential of inorganic sulphate salts (copper sulphate and iron (II) sulphate) as triggers for activation of stored SpliNPV in S. littoralis 4th instar larvae was evaluated under laboratory conditions. Obtained results showed that the ability of sulfate salts to activate infections varied according to the type of tested chemical. Results also showed that copper sulphate and iron sulphate triggered lethal effect of polyhedrosis disease in larvae with range of 10.0-20.0%. In addition, results showed that observed larval mortality due to treatment with copper sulphate and iron (II) sulphate ranged from zero to 45%. This might be due to the intrinsic toxicity of the tested compounds. It was noticed that copper sulphate alone at different concentrations caused higher mortality percentage than iron (II) sulphate. It could be concluded that trace metals such as copper and iron can clearly modulate baculovirus induced disease, probably due to their different roles in insect immune functions. Further work is required to identify useful virus activation substances under field conditions.
