Abstract
The present study aimed to investigate the effect of a synthetic
pyrethroid insecticide, cypermethrin, on the salivary glands of the American
cockroach, Periplaneta americana. Insecticide cypermethrin of the concentrations
0.0005% and 0.005% was provided in feed to adult cockroaches to examine the
alterations from normal histology of salivary glands after treatment. Results
indicated that salivary glands were highly affected after 24 hours post-treatment.
The changes observed in the cypermethrin-treated salivary gland were
categorized by alteration in shape and size, degeneration and swelling of
central and peripheral cells, elongation of duct epithelial cells, and
contraction of duct lumen as compared to the control group. The damage caused
by cypermethrin in the salivary gland acini and duct developed more extensively
as the concentration of cypermethrin increased.
