Mortality percentages of the following concentrations 0.5, 1, 2, 3gram (w/w) of powders which were mixed with crushed wheat grains were calculated after 96 hours, percentage of the repellency effect of the same concentrations were calculated after 48 hours. The results showed highly significant differences among concentration of powder. Also results showed significans effect of Piper nigrum powder at concentration 3g , for repellency effect with value 9.590% while the value for C. annuum and Z. officinale powders at the same concentration were 8.665% and 6.000% respectively well as the insecticidal effect for concentration 3g were 6.312%, 7.360%, 4.000% C. annuum, P. nigrum and Z. officinale powders respectively . | ||
