The results depicted in Table 5 again showed that the sawtoothed
grain beetle was more sensitive to both essential oils
mainly to A. absinthium oil. The corresponding LD50 and LD95 values
were 0.209 and 1.963 L. Whereas, the red flour beetle was
more tolerant to both oils, mainly A. herba-alba oil with corresponding
LD50 and LD95 values of 7.432 and 133.323 L. Indeed,
results revealed significant statistical differences between lethal
doses means of oils (Table 5).
