- Abstract
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.
