Calamusenone [3,8-dimethyl-5-（1-methylethylidene）- 1,2,3,4,5,6,7,8-octa- hydroazulene-6-one, C15H22O] from Acorus gramineus Soland rhizome was tested in the laboratory for its insecticidal activities against adults of sitophilus zeamais Motsch. and Rhizopertha dominica （Fab.）, using dry film contact and fumigation methods. Responses varied with insect species, dosage and exposure time. in the dry film contact experiment, the highest insecticidal effects of calamusenone against S. zeamais and R. dominica adults were produced at 170.32μg/cm2 after treatment for 72 h, with 96.2% and 98.7% mortalities, respectively. The median lethal concentration （LC50）（72 h） values of calamusenone against S. zeamais and R. dominica adults were 67.00 μg/cm2 and 77.30 μg/cm2, respectively. As a potential fumigant, calamusenone showed moderate insecticidal effect on the adults of S. zeamais and R. dominica in fumigation experiment, with their LC50 （120 h） values of 125.71μL/L and 93.64μL/L respectively. Calamusenone isolated from A. gramineus rhizome showed promise as a novel pesticide candidate for stored-product pest control.

i>Sitophilusi> zeamais is a primary pest of stored maize, which can cause quality and quantity losses. Maize is cultivated in several West African countries where different agro-climatic and agro-ecological conditions exist. These conditions could influence the i>Sitophilusi> zeamais morphology. Thus, the purpose of this study is to identify the i>Sitophilusi> zeamais morphological groups in the four countries. This was carried out through the morphometric study of 30 male i>Sitophilusi> zeamais individuals taken from the yellow maize in each country, by measuring with a binocular magnifying glass, 16 variables of the different tagmas belonging to the insect. Subsequently, statistical analyses were firstly carried out with the raw measurements, such as the principal component analysis, in order to extract the contribution of the variables on each factorial axis and to visualise the correlations between the variables. Taking the case of the transformed measurements, in addition to the principal component analysis, a discriminant factorial analysis was carried out to find out the best factor for gathering individuals according to their morphology, a confusion matrix to summarise the individualily:Verdana;">ily:Verdana;">ily
