Abstract
A cuticular structure was found in the larva of
Manduca sexta (Johannson) and studies were carried out
to determine whether it gives rise to the internal
ocellus of the imago. A study using light and scanning-
electron microscopy was made of the structure, termed
the "larval ocellus", and ablation techniques (cautery
and surgery) were used on M. sexta larvae and tested for
effects on the imaginal ocelli. A similar study using
only cautery was made for comparative purposes on
Trichop1usia ni (Hubner.)
