Abstract

The Otis New Jersey gypsy moth (Lymantria dispar L.) strain is considered the "white rat" of gypsy moth research. This strain has been laboratory reared for 34 generations. It currently consists of 35 subcolonies or cohorts that have been genetically isolated from one another for several generations. Usually, larvae that hatch at the same time develop synchronously; however, in recent years this strain has been plagued by periods of asynchronous larval growth (straggling) and other performance abnormalities. These abnormalities are now collectively called Abnormal Performance Syndrome (APS).
