DescriptionThe Lymantria dispar multicapsid nucleopolyhedrovirus (LdMNPV) is used on a limited basis as a gypsy moth (L. dispar) control agent. In an effort to improve the efficacy (i.e., killing speed) of the LdMNPV, we generated a recombinant viral strain (vEGT-) that does not produce the enzyme ecdysteroid UDP-glucosyltransferase (EGT). We compared the potency and efficacy of vEGT- to wild-type virus (A21-MPV) and the impact of vEGT- and A21-MPV on larval weight gain. Bioassay of L. dispar 1st, 4th, and 5th instars showed no significant difference in the LC50 values in larvae infected with vEGT- or A21-MPV.
