abstract
The investigation was carried out in Cuttack and Jagatsinghpur districts in the year 2018 with collection of data by several methods. Four months of study and survey yielded 52 insect species out of which 19 were found damaging the productivity of the pulse field. Although the insect pest population was high in the studied field but the damage caused by them was not significant because the beneficial insects are playing a crucial role in controlling the pest and increasing the yield indirectly. The pest species of Cuttack was found higher than Jagatsinghpur. Aphis craccivora, Euchrysops cnejus and Empoasca kerri were found to be the most abundantly present pest of Eastern Odisha. The incidence of Coleopteran pest was higher than the other 4 orders. Along with the pests, 23 beneficial insects were found which help in increasing the productivity of the pulse field in several ways. Ladybird beetle, Dragonfly and Praying mantis were found to be the most abundant beneficial insect of the field. The dominancy of beneficial insect was seen in the surveyed greengram field. Some predatory and parasitoid beneficial insects have the controll over the pest population. Ten neutral insects were also seen, which don’t have any significant role in the studied agroecosystem. A new insect species named Cossyphus depressus was found from the field which was never reported before from Odisha.
