Comparative analysis of Dysdercus koenigii testis protein (quantitative) after the application of different insecticides

Estimation of total proteins and the effect of different concentrations of insecticides viz., multineem, neemjeevan, imidacloprid, monocrotophos, quinolphos and oxydemeton-o-methyl on the testis of D. koenigii was carried out. Fourth instar nymphs were treated with desired concentrations of different insecticides and the estimation was made at age interval i.e. 1-day, 4-day and 7-day old after emergence. The nymphs when transformed into adults were dissected and testis was taken out for the estimation purpose. The protein of male derived from IV instar was more inhibited by synthetic insecticides than neem products at different age intervals. 0.01, 0.02 and 0.04 percent concentration of multineem did not significantly inhibit the testis protein. In case of oxydemeton-o-methyl the inhibition was significant as compared to control. Quinolphos significantly inhibited the amount of testis protein in 1-day old males whereas in 7-day old it was insignificant.
