of adult </span><i style="line-height:1.5;">Periplanata</i><span style="line-height:1.5;"> </span><i style="line-height:1.5;">americana</i><span style="line-height:1.5;"> was the highest (92) in 50 g leaf powder and the lowest (2) in the control.
The result also showed that the highest mortality (125) was recorded in 96 hr
exposure time while the lowest
(28) was recorded in 24 h exposure time. The
Analysis of Variance (ANOVA) for the mean mortality in the experiment and the
control indicated that there was significant difference (P-value = 0.05) in the
mortality with increase in grams and exposure time of leaf powder and the
control at 5% level of significance the mean mortality count of adult </span><i style="line-height:1.5;">P. americana</i><span style="line-height:1.5;"> was the highest (108) in 50 ml ethanoic extract an</span><span style="line-height:1.5;">d the lowest (3) in the control.
The result also showed that the highest mortality (144) was recorded in 96 hr
exposure time while the lowest

Analysis of Variance (ANOVA) for the mean mortality in the experiment and the
control indicates that there is significant difference (P-value = 0.05) in the
mortality with increase in grams and exposure time of leaf powder and the
control at 5% level of significance. The
efficacy of</span><i style="line-height:1.5;"> Azadirachta indica</i><span style="line-height:1.5;"> Ethanol extract is more than the leaf
powder. There was significant difference in mortality in both increase in concentration
levels and exposure time at 5% level of significance in both leaf powder and
ethanol extract.</span>
