The investigation on Seasonal Incidence and Management of Sucking Insect Pests of Green Gram [Vigna radiata (L.) Wilczek] under semi-arid condition was conducted at Agronomy Farm, S. K. N. College of Agriculture, Jobner (Rajasthan) during Kharif, 2015. The initiation of jassid and whitefly population recorded in the first week of August (32 SMW) which reached its peak in first week of September, i.e. 36^th SMW (12.90 jassid and 14.20 whitefly/ three leaves) when maximum temperature, minimum temperature and relative humidity was 36.1 and 21.7 ⁰C and 90 percent, respectively and gradually decline thereafter. The relationship between jassid, Empoasca motti population with maximum temperature, minimum temperature, relative humidity and rainfall revealed negative correlation (r=-0.621, r=-0.289, r=-0.425, r=-0.329, respectively). The whitefly, Bemisia tabaci population with maximum temperature revealed significant positive correlation (r=0.764) but minimum temperature, relative humidity and rainfall revealed negative correlation (r=-0.288, r=-0.515, r=-0.282, respectively).The population of sucking pest (jassid and whitefly) and Coccinella septempunctata had a significant positive correlation (r=0.886).
