abstract
The rice hispa (Dicladispa armigera) is a sporadic and occasional leaf feeding pest of rice. It is a one of those pests whose infestation has increased a lot in recent years. Present experiment was carried out to determine the relative bio efficacy of some newer insecticides against rice hispa. Among the nine insecticides application of Spinetoram 6SC+Methoxyfenozide 30SC @400 ml/ha was found to be most effective. But it was at par with Spinetoram 6%SC+ methoxyfenozide 30% SC@ 375ml/ha (0.74%). The highest damage of 7.14% LDH was observed in case of untreated crop of rice. The peak duration of the occurrence of rice hispa was almost from 25 days and onward period during both of years of the experimentation.
