Abstract

Pilocarpine fed to Drosophila larvae in concentrations of 1, 10, 100, or 1000 p.p.m. induced depletion of all synthesized material from the larval salivary gland cells, as shown by loss of cytoplasm granularity and changes in cell shape.

Determination of the nuclear and nucleolar diameters of salivary gland cells from the several treatments showed a reduction in nuclear to nucleolar diameter ratio after 10 or 100 p.p.m. treatments.
