UTTAR PRADESH JOURNAL OF ZOOLOGY

The survey was conducted to record the population dynamics of major sucking pests of groundnut such as Aphid, Aphis craccivora, Thrips, Scirtothrips dorsalis and Leafhopper, Empoasca kerri during Rabi, 2019- Summer, 2020 and Kharif, 2020. Incidence of aphids was observed from the 52^nd Standard Meteorological Week (SMW) but a considerable population was recorded from the 06^th SMW to the 18^th SMW. Thrips were high during the 4^th SMW to the 18^th SMW but the peak incidence of thrips was observed 16^th to 18^th SMW. The infestation of leafhoppers was observed from the 2^nd SMW and the incidence increased and reached a peak during the 8^th SMW. A considerable level of incidence was observed from the 6^th SMW to the 17^th SMW during Rabi, 2019- Summer, 2020. The relationship between the weather factors and major sucking pests during Rabi-Summer and Kharif seasons revealed the positive relationship between aphids and thrips with maximum temperature, minimum temperature and mean temperature and the negative relationship with maximum humidity, minimum humidity, mean humidity and rainfall. Leafhoppers had a non-significant relationship with weather factors but had a significant negative relationship with rainfall.
