DescriptionRecent experimental findings demonstrate that two distinct waves of mortality of gypsy moth larvae from nuclear polyhedrosis virus (NPV) occurs during larval development. The evidence suggests that early instars acquire lethal doses of NPV from the surface of the egg mass and the cadavers of these larvae produce inoculum that causes a second wave of mortality among late instars. Transmission of NPV between gypsy moth generations appears to occur primarily by way of contamination of egg masses from environmental sources during oviposition. Other factors influencing NPV epizootiology including Foliage chemistry, weather and genetic effects are discussed.
