  • Vasantrao Naik Marathwada Krishi Vidyapeeth, Department of Agricultural Entomology, India


Highest population of Coccinella septempunctata after first spray was observed in untreated control (1.92) followed by Bt (1.70), Beauveria bassiana (1.66) whereas during second spray more number of C. septempunctata observed in untreated control (2.01) followed by Azadirachtin 1500 ppm (1.77) and NSKE 5% (1.74). The population of Chrysoperla arabica was highest in untreated control (1.47) followed by NSKE 5% (0.99) and Beauveria bassiana (0.96 ) during first spray and after second spray observed in untreated control (1.30) followed by Beauveria bassiana (0.94) and Nomuraea rileyi (0.93).
