* The original insect mortality data were corrected by Abbott's formula and then transformed into arcsin √percentage values before ANOVA and DMRT test.
* The figures in parentheses represent transformed arcsin √percentage data
* Values followed by different letters within a column, are significantly different at the 5% level of probability (Duncan's multiple range test)
* HAT = Hours after treatment
* Sx = Standard error of mean
