Present study focus on the potential use of neem extracts in controlling Xanthopimpla predatorinfestation on Anthereae mylitta drury(Daba T.V)cocoons. Effectiveness of neem extracts against Xanthopimpla predatorinfestation was studied during first, second and third crops of Anthereae mylitta drury (Daba T.V). Neem leaf and neem seed extracts were evaluated against Xanthopimpla predator under field conditions. Spraying of neem seed extract (T3) increased the effective rate of rearing in all the three crops compared to neem leaf extract (T2) and the control batch (T1). It was found that in all the three batches the infestation % was high in third crop. The maximum Xanthopimpla infestation was observed in control cocoons (without any spray). The neem leaf extract sprayed on Daba T.V cocoons had reduced 51.42-73.18 of Xanthopimpla infestation in all the three crops while neem seed extract reduced 71.43-82.93% of Xanthopimpla predator infestation during the three crops. It is also found that in T1, T2 and T3 batches, the percentage of female cocoons infested was less than the male cocoons in all the three crops Present results also show that, the pupa of 4, 5 and 6 days old were selected for maximum infestation in all the three batches. Meteorological data pertaining to the rearing field report the peak period of Ichneumon fly incidence as November, December and January (Third crop).
