Conteúdo: 	Intraplant distribution of eggs, larvae and predators of the bollworm (Heliothis zea (Boddie) on cotton (Gossypium hirsutum L.) was studied in field trials during 1986 and 1987 in Oklahoma. The largest proportions of eggs were found and the main stem terminals and upper parts of the plant. The total bollworm eggs on terminal and total eggs on the whole plant showed significant relationships, which suggests that the main stem terminal can be used as sampling site for bollworm eggs. Larvae were more commonly found on squares, bolls and flowers. Although large proportions of eggs were laid on the main stem terminals and on leaves, very small proportions of larvae were found on these parts. Chi-square tests between total numbers of eggs, total numbers of larvae on the upper of the plant and total numbers of predators on the whole plant showed no dependence in all planting dates.
