mortality rate of insect population (%) = number of dead insects/total number of treated insects × 100
Corrected mortality (%) = [ (population mortality in treated group-population mortality in control group)/(population mortality in 1-control group) ] × 100
Virulence index TI = (standard drug LC) 50 Test agent LC 50 )×100
