Resumo:  Five larval instars of the bollworm, Heliothis zea Boddie were fed on five cotton plant parts and an artificial diet. Their effects on larval development and survival were analysed. The results showed that the highest mortality in first instar was for those placed on bolls. For the second and third instars, flowers, bolls, squares and leaves proportionated the highest percentages of survival. The lowest survival rate for the fourth instars was found on squares. The fifth instars showed high rates of survival on bolls, leaves and the artificial diet. Larval establishment was highly significant for larvae fed on flowers when compared with those fed on bolls. Larvae fed on terminal, leaves and squares took the longest time to reach the sixth instars. Pupae from artificial diet, bolls, and leaves were the heaviest.
