Effect of Different Management Treatments on Whitefly Parasitization by Encarsia spp. under Field Condition on Cotton

Effect of different management modules on Encarsia spp. at different intervals during Kharif, 2015 was studied. Maximum parasitization 32.28 and 31.50% was recorded in T12 [Control (without water spray)] in both the intervals (5- and 10-days interval) followed by 30.30 and 29.85% in T2 nimbecidine (six sprays at 5 days interval) + Yellow sticky trap in both the intervals, respectively. While minimum parasitization (15.02 and 14.91%) was recorded in T5 [First spray of dimethoate followed by imidacloprid, thiamethoxam, triazophos, imidacloprid and thiamethoxam (at 5 days interval)] and T8 [first spray of nimbecidine followed by dimethoate, triazophos, novaluron (at 10 days interval)], respectively. It is concluded that high whitefly pupae parasitization was found in neem treated plots than insecticide treated plots. So, nimbecidine was found relatively less toxic and much safer to natural enemy.
