Chronic effect of carbaryl on the levels of total protein, total free amino acids and total glucose in the male reproductive system of Iphita limbata stål. (Heteroptera: Pyrrhocorridae)

the application of sub-lethal dose (0.6 μg/2 μl/insect) of carbaryl for a period of 60 days caused changes in the biochemical constituents in the male reproductive system of a heteropteran bug, Iphita limbata. the difference in total protein up to 15^th day was not significant, thereafter the levels of total protein declined from 30^th day onwards and significant reduction in the levels of total protein total free amino acids and total glucose was observed on 45^th day (p < 0.05) and 60^th day (p < 0.001) of treatment. similarly treated insects showed significant (p < 0.001) decrease of total free amino acids and total glucose on 45^th and 60^th days of treatment period.
