英文摘要	The present study aimed to highlight the insecticidal activity of the Algerian desert truffleTerfezia claveryiChatin against two post-harvest pests of rice and other cereal products, the rice weevilSitophilus oryzae(L.), and the lesser grain borerRhyzopertha dominica(F.), using direct contact application method with the filter paper impregnation technique. Soxhlet apparatus was used for extraction with chloroform as solvent. The major compounds in chloroform extract ofT. claveryiwere identified using gas chromatography-mass spectrometry (GC-MS). The two-way ANOVA was used for statistical analysis to determine the exposure time and doses with the greatest insecticidal activity. Findings of this study revealed that the major compounds were fatty acids: linoleic acid, methyl ester (14.84%), 11,14-eicosadienoic acid, methyl ester (11.55%), oleic acid, methyl ester (7.1%), and palmitic acid (6.96%). However, chamazulene (0.88%) was found to be minor compound. Our results describe for the first time the presence of chamazulene in desert truffle. The result showed also that the most potent insecticidal activity of chloroform extract ofT. claveryiwas found towardsS. oryzeawith LD(50)value of 162.11 mu g/mL. For concentrations of 250 and 300 mu g/mL, this extract was able to eradicate 96.65 +/- 1.15% and 100.0 +/- 0.0% ofS. oryzeaafter 24 h of exposure. However, it caused only 47.24 +/- 1.15% and 50.66 +/- 1.15% of mortality ofR. dominica, respectively, after 6 days. This work offers promising prospects for the use of desert truffles extracts as a potential insecticidal agent for improving quality and safety of stored foods against damage caused by stored-product pests.
