In conclusion, the results of the present study provide
evidence that essential oils from plants within the
Lamiaceae family and their volatile constituents interfere
with the feeding activity of T. tabaci females. If
effective in field cultures of leek, application of plant
volatiles might prevent qualitative crop losses due to
severe feeding damage on green leaf parts. The prospect
of crop protection against thrips pests by means of
behavior-controlling natural products such as plant
volatiles is promising since theyare generally regarded
as not toxic to non-target organisms and do not persist
in the environment (Isman, 1999).
