Abstract
Gypsy moth cohorts from 10 near-wild strains (one to six previous generations in culture), six wild strains (field-collected egg masses), and the standard "New Jersey" lab strain (34th and 35th generation in culture) were reared on Otis wheat germ-based artificial diet, in a constant environment. Rearings were begun with newly-hatched first instars; pupae were later collected daily, sexed, and weighed. Pupal lengths and maximum body widths were measured for some lab strain females. Collected pupae were classified as morphologically "normal" or as possessing at least one of seven types of morphological abnormalities, then reared individually to adult eclosion.
