Lymantria dispar multicapsid nuclear polyhedrosis virus

"Lymantria dispar" multicapsid nuclear polyhedrosis virus or LdMNPV is a viral infection in gypsy moths that causes infected larvae to die and disintegrate. Infected larvae climb to the top of a tree and die. The larvae then melt or disintegrate, falling onto the foliage below, where they infect more larvae.
