BIOCHEMICAL ASSIMILATIONS IN THE GONADS OF CHROTOGONUS TRACHYPTERUS (BLANCHARD)(ORTHOPTERA: ACRIDIDAE) EXPOSED TO SUB LETHAL DOSE OF CHLORPYRIFOS AND FENVALERATE

To evaluate the effects of sub-lethal doses of chlorpyrifos (303.5 and 74.9 ppm) and fenvalerate (52.5 and 42.7 ppm) on gonads of adult male and female of chrotogonus trachypterus (blanchard) were analysed respectively. biochemical analysis on different parameters such as protein, cholesterol, alkaline phosphatase and atpase were evaluated at 12, 24 and 48 h treatment. hypoproteinemia (p<0.01) exhibited at 12, 24 and 48 h after applying chlorpyrifos in both sexual category. fenvalerate led to hyperproteinemia (p<0.01) at 24 and 48 h in males and females, while at 12 h non-significant boost in males. cholesterol level was highly significantly (p<0.001) decline after exposed to chlorpyrifos till 48 h whereas, introduced to fenvalerate, accumulation of cholesterol level in gonads was highly significantly (p<0.001) enhanced at 12, 24 and 48 h of adult male and female. a non-significant decrease in alkaline phosphatase activity was recorded at 12 h in males, subsequently more significant (p<0.01) at 24 and 48 h after using chlorpyrifos. fenvalerate showed fluctuation in alkaline phosphatase level like gradually significant (p<0.05) increase at 12 h and after that significantly declined at 24 and 48 h in both cases. chlorpyrifos and fenvalerate both explained highly significant (p<0.001) increase in the storage level of atpase at 48 h in male and female adults. to achieve the potential toxicity among insecticides in biochemical activity of pest management by affecting their reproductive physiology through gametogensis and fertility control.
