Lymantria Dispar Multicapsid Nuclear Polyhedrosis Virus (LdMNPV)

Lymantria Dispar Multicapsid Nuclear Polyhedrosis Virus


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.
