Abstract: In the present study an investigational work was performed to find out the presence of neurosecretory cells in the ventral nerve cord of Spodoptera litura. The Insect Ringer solution was used for dissection. Specimens were kept in ringer solution and dissected out. A diluted solution of methylene blue was used for staining. Aqueous Bouin’s fixative was used for fixing specimens heads. After fixation heads were cut into sections ranges from 6 µ to 10 µ and stained by stained aldehyde fuchsin. ‘B’ and ‘C’ type of neurosecretory cells was observed in the ventral nerve cord of Spodoptera litura but ‘A’ and ‘D’ type of cells were absent in the ventral nerve cord of Spodoptera litura. Information regarding the size, shape and distribution of ‘B’ and ‘C’ type of cells is provided in detail.
