- Abstract
Fumigant toxicity of the essential oil from Artemisia haussknechtii (Boiss) belonging to the family Asteraceae, was assessed against the larvae (10 and 25 days old) and adults (1-7 days old) of the confused flour beetle Tribolium confusum (Jacquelin du Val) (Coleoptera: Tenebrionidae). Dry ground plant was subjected to hydrodistillation using a Clevenger-type apparatus. The resulting oil contained camphor (29.24%), 1, 8-cineole (27.62%), and yomogi alcohol (5.23%) as the major compounds. The essential oil was toxic on three insect stages with LC50 values ranging between 27.37 and 115.93 μl/l air, depending on the insect stage, concentration, and exposure time. From the three stages of T. confusum, the 25-day-old larvae were more tolerant, and adults were more susceptible than other stages. These results suggested that the essential oil of A. haussknechtii have potential as a control agent against larvae and adults of T. confusum.
