Abstract:
Chlorpyriphos were slightly harmful to the predator, Chrysoperla zastrowi. Higher egg mortality was recorded with chlorpyriphos at 2000, 1500, 1000 and 750 ml/ha (65.00%, 62.00%, 61.33% and 56.00% respectively). The low grub mortality was observed in chlorpyriphos 20 EC 750 ml/ha (51.00%) at 48 hours of treatment whereas it was high in chlorpyriphos 20 EC 2000 ml/ha (82.50%) followed by chlorpyriphos 20 EC at 1500 ml/ha (77.50%), chlorpyriphos 20 EC 1000 ml/ha (60.00%) and Dursban 20 EC 1000 ml/ha (62.50%). Treatment II also showed that, the per cent mortality after 48 h due to the concentration of chlorpyriphos 20 EC at 1000, 750, 500 and 250 was 70.00, 66.67, 60.00, 44.00, whereas it was also high in Dursban 20 EC 500 ml/ha recorded 63.33 per cent mortality compared to dimethoate 500 ml/ha 46.67 per cent mortality. Chlorpyriphos were slightly harmful to the predator, Chrysoperla zastrowi.
