The initial spring infestations of the cotton leaf worm, Alabama argillacea (Hbn.) are generally considered to originate from moths migrating from southern regions perhaps thousands of miles away (Walcott 1929). There is no evidence that this insect can undergo a diapause in any of its stages and thus survive unfavorable conditions in any area. Very little is known about the insect throughout South America where it is one of the major pests of cotton, and where infestations in the United States are thought to originate. A knowledge of such movements may throw some light on the origin of the pest.
