Abstract: This study was aimed at determining the larvicidal properties of Balanites aegyptiaca, Calotropis procera and Eucalyptus globulus leaves and roots ethanolic extracts against fourth instar mosquito larvae. Twenty batches of fourth instar larvae were exposure to various concentrations of 2,4,6,8 and 10ppm for 24hrs and were assayed according to WHO guidelines for testing laboratory and field mosquito larvicides. Larval mortality was observed after 24hrs and recorded. Results are mean of three replicates. Percentage mortality was calculated using Abbott’s formula, while the LC50 was determined by a log dosage probit mortality regression line at 95%CI. One way ANOVA was performed to determine the difference in larval mortality between plant parts. Results obtained shows that B. aegyptiaca leaves and roots elicited the highest percentage mortality of 60% and 73% at 10ppm respectively. The lowest mortality was recorded in E. globulus leaves and roots as 63% and 64.67% at 10ppm respectively.
