*Test performed on S. oryzae and R. dominica two weeks old adults and P. interpunctella their instar larvae.
**LT50 and LT95 values significant difference (p < 0.05) is based on non-overlap of the 95% C.I.
***Since Chi square goodness of fit test is not significant (p > 0.15), no heterogeneity factor is used in the calculation of fiducial limits.
