Figure 1

Mean Mortality (%±SE) of adults of red flour beetle, T. castaneum treated with different concentration of deltamethrin and phosphine. Error bars sharing different means are significantly different at 5 % level (P < 0.05; Tucky HSD test; n=20). 

Figure 2

Mean Mortality (%±SE) of adults of lesser grains borer, R. dominica treated with different concentration of deltamethrin and phosphine. Error bars sharing different means are significantly different at 5 % level (P < 0.05; Tucky HSD test; n=20).
