Popis:	Studies were conducted to determine the effect of pigmentation on the field survivorship of larvae of the tobacco hornworm, Manduca sexta (L.). Larvae of the white-mutant tobacco hornworm were found to have a lower mean survival rate as compared with black-mutant and wild-type strains. Tests in the greenhouse demonstrated the larvae of the white-mutant were able to establish on the tobacco plants as well as the black-mutant and wild-type strains. Differential predation seems to be an important factor in the low recovery of the white tobacco hornworm in the field. Parasitism rates by Cotesia congregata (Say) were low for all three strains.
