Table 2 Lethal effects of different concentration of A. indica, J. curcas and Solignum on Coptotermes sjostedti (Isoptera: Rhinotermitidae) at different time of exposure on wood from Ceiba pentandra (L.) Gaertn

From: Termiticidal activity of oil from Jatropha curcas L. and Azadirachta indica A. Juss against Coptotermes sjostedti Holmgren (Isoptera: Rhinotermitidae)

Data (%) were transformed (arcsine) before the analysis of variance; Means (± Standard error) are values of four replicates; Means with the same lower case alphabet in a column are not significantly different from each other (DNMRT: P > 0.05); ^bconcentration (mL/ 100 m³ of wood surface); P = Probability value
