The present investigation was carried out to study the seasonal incidence of brown plant hopper infesting rice during two consecutive seasons, viz., Kharif 2022 and Kharif 2023 at Agricultural Research Station Shirgaon Dist. Ratnagiri, under Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli. The results revealed that the seasonal incidence of BPH started during the 33^rd SMW (0.30) BPH/hill, and reached its peak level in the 39^th SMW (19.05) BPH/hill. The weather parameters such as maximum temperature, minimum temperature, morning relative humidity, evening relative humidity, bright sunshine, wind speed, and rainfall play an important role in the abundance of BPH. The investigation revealed that the weather parameters contributed to 58.0 percent in 2022 and 50.0 percent in 2023 of the total variation in the population of BPH on rice.
