Adult survival of T. tabaci females on the leaf surface
was not significantly affected by essential oil application
after 24 h (Table 4). A similar result was found with four
of the five tested plant volatiles (Table 5).Application
of a-pinene, 1,8-cineole, linalool and eugenol had no
lethal effect on thrips females. In contrast, terpinen-4-ol caused 14.3%, 8.9% and 16.1% mortality at 0.01%,0.1%, and 1% concentration, respectively.
