Abstract:
Ultrastructural changes in the prothoracic gland cell cytoplasm of larvae of the L4 and L5-stages of the tobacco hornworm Manduca sexta (Johansson 1763) were investigated in untreated controls and animals injected with the natural insectizide azadirachtin [Aza]: At each dosage, tested Aza treatment results in a significant prolongation of both larval stages. In each larva injected with more than 0.5 .mu.g/g body weight, growth is reduced and ecdysis retarded. The development of the prothoracic gland cells is inhibited but no cytotoxical effect can be observed. The prothoracic gland cells of those Aza treated larvae of the L5-stage that form a praepupa differ markedly from those that moult incompletely to a L6.
