title: Toxic effect of Atalantia monophylla essential oil on Callosobruchus maculatus and Sitophilus oryzae.
abstract: The hydrodistillated essential oil of Atalantia monophylla was subjected to GC-MS. Forty compounds were presented in the essential oil. Eugenol (19.76 %), sabinene (19.57 %), 1,2-dimethoxy-4-(2-methoxyethenyl) benzene (9.84 %), beta-asarone (7.02 %) and methyl eugenol (5.52 %) were found the predominant compounds. The oil was tested for fumigant toxicity and repellent activity against Callosobruchus maculatus and Sitophilus oryzae. The development stage of C. maculatus fecundity, adult emergence and also ovicidal activities were studied by the treatment of A. monophylla oil. The oil exhibited considerable fumigation toxicity (70.22 %), repellent activity (85.24 %) and ovicidal activity (100 %) against C. maculatus. The oil significantly reduced the protein, esterase, acetylcholinesterase and glutathione S-transferase on C. maculatus and S. oryzae. It can be considered that A. monophylla has a potential insecticide against stored product pests.
