Table 1 Percent mortality (mean ± SE, n = 5) of 2nd instar Pectinophora gossypiella larvae due to Beauveria bassiana, Verticillium lecanii, Metarhizium anisopliae concentrations and Azadirachta indica extract (alone and in combination) at different exposure intervals. Means sharing with same lower case letters are not significantly different from each other at 0.05 level of significance, i.e., P < 0.05
