摘要:This study was aimed at assessing the chemical composition and fumigant toxicityof Pistacia lentiscus L. essential oil leaves against Tribolium castaneum adults in thefloor mill conditions. GC/MS analysis showed that essential oil contains α-Pinene(18.48%), β-Myrcene (22.59%) and Sabinene (8.67%) as major compounds.Response surface methodology was used to optimize the fumigant toxicity ofPistacia lentiscus L. essential oil leaves from Tunisia against adults of Triboliumcastaneum L. (Herbst, 1797) developed during wheat flour storage. The effects oftwo parameters namely storage period and wheat flour occupation space, on Tcastaneum mortality were studied. Different storage periods (15, 30 and 45 days)and occupation spaces (0, 50 and 100 %) were experimented. The fittedmathematical model allowed us to determine optimal conditions of P. lentiscusleaves essential oil fumigant toxicity. Results clearly indicated that the spaceoccupation was the main factor influencing the mortality percentage of T. castaneumadults. The selected optimal conditions were obtained for an occupation space of30% and a storage period situated between 15 and 45 days. In these optimalconditions, mortality percentage can reach 85%.
