The regression analysis of variance further confirmed that there was an increasing trend in mean mortality of insects after 48 hours of treatment [for SMH: b= 3.1± 0.9, F (1,4) = 106.78, P = 0.001, for KTCH: b= 3± 2.63, F (1,4) = 3.42E+ 32, P= 3.48E- 49 and for KLPT: b= 2.7± 0.1, F (1,4) = 729, P= 0.001) ( Fig. 1 – 3(a) ].
