Lymantria Dispar Multicapsid Nuclear Polyhedrosis Virus (LdMNPV)
This virus is a naturally occurring virus specific to gypsy moth caterpillars (Lymantria dispar). It spreads like the common cold and is effective at reducing high-density gypsy moth populations. The virus is always present in
gypsy moth populations and can be transmitted from a female moth to her offspring. It spreads naturally
through the gypsy moth population, especially when caterpillars are abundant. During a gypsy moth outbreak, caterpillars become more susceptible to this virus because they are stressed from competing with
one another for food and space. NPV is especially important during gypsy moth outbreaks in North America.
Caterpillars killed by the NPV disease hang in an upside down V shape. Their bodies liquefy and rapidly disintegrate.

''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.
Often referred to as Gypchek, the virus goes by multiple names. Gypchek is an insecticide which uses the virus to control the gypsy moth population. Because the virus only infects.. more
