The activity of phenoloxidase in haemolymph plasma is not a predictor of Lymantria dispar resistance to its baculovirus
PO activity was measured in haemolymph plasma of 4th insar larvae. The challenging was done perorally with two different strains of LdMNPV: LdMNPV-27/0 isolated in Asia and LdMNPV-NY isolated in North America. PO activity is normalized to 1mg of protein (A) or to 1 μl of haemolymh (B). The results of the ANOVA comparision are given within the figure.
