Seasonal Incidence of Thrips (Megalurothrips usitatus) and Pod Bug (Clavigralla gibbosa) on Kharif Mungbean in Tropical Zone

A two-year study (2022-2023) investigated the seasonal incidence of thrips (Megalurothrips usitatus) and pod bug (Clavigralla gibbosa) on Kharif mungbean in relation to weather parameters. The maximum thrips population during 2022 was observed in early, timely and late sown crops, with 2.60, 2.00 and 2.60 adults/10 flowers in 36^th and 37^th standard meteorological weeks (SMW), respectively. In 2023, peak thrips populations were 2.40, 0.60, and 1.32 adults/10 flowers for early, timely, and late sown crops during the 37^th SMW. Correlation studies revealed a significant positive association of M. usitatus with temperature parameters in 2022 and with relative humidity and rainfall in 2023. The highest C. gibbosa populations in 2022 were 5.20, 3.50, and 4.26 adults/plant during the 37^th SMW across early, timely, and late sown crops. I n 2023, C. gibbosa first appeared in the early sown crop during the 33^rd SMW (0.42 adults/plant), with peak at 3.80 adults/plant in the 38^th SMW. Timely and late sown crops recorded peak C. gibbosa during the 37^th SMW (2.76 and 3.34 adults/plant).
