The repellent activity of essential oil from Artemisia absinthiumArtemisia absinthium
was evaluated against adults of Tribolium castaneum. The repellency
test was conduced using an experimental arena consisting of
in five circular glass boxes, the central box was united to the other
boxes with glass tubes, diagonally. The samples and the controls
were distributed respectively in two opposed boxes containing 4 g
of treated and untreated diet with solvent alone. The solvent used
was hexane. In the central box forty adults were released. After 24
h the number of adults present at the boxes were counted. Each
concentration was tested three times. Preference Index was calculated
as PI= (% of insects at treated diet)-(% of insects at untreated
diet) / (% of insects at treated diet)+(% of insects at untreated diet)
where PI = -1 to 0,10, repellent plant; PI= -0,10 to +0.10, Neutral
plant and PI= +0,10 to +1, attractant plant. At 0.04% PI was -0.42
and at 0.4 PI was -0.77.Tribolium castaneum. The repellency
