Sub - lethal effect of phytopesticide nimbecidine on biochemical changes in the adult male insect Sphaerodema rusticum (Heteroptera: Belostomatidae)

Carbohydrate, protein and lipid are the major components of the body playing important role in the body construction and energy metabolism. Effect of sub -lethal concentration (0.00028 ppm 1/10th of LC50) of the phytopesticide nimbecidine was studied on Sphaerodema rusticum for 7, 14 and 21 days of exposure. A significant decline in the contents of glycogen, protein and lipid and an increase of glucose and amino acid contents of fat body, testis and seminal vesicle were observed. It was observed that the biochemical changes in the nimbecidine treated (7, 14 and 21days) fat body, testis and seminal vesicle were significantly differed than control.
