    Description

    The biological activities of the viral preparations Virin NSH and Gypchek were determined for two Western Siberia populations (Tatarsk and Altai) and for one American (New Jersey) population of gypsy moth, Lymantria dispar L. There were no significant differences in potency between the two preparations when tested against the Tatarsk population of L. dispar. Gypchek was significantly more active than Virin NSH against the New Jersey population of insects. The LD50 of Virin NSH for the Altai population of the herbivore was lower than the LD50 for the Tatarsk population. Both Virin NSH and Gypchek were more active against insects reared on artificial diet than those reared on foliage.
