The studies entitled "Population build-up and seasonal occurrence of pod bug Clavigralla gibbosa (Spinola) in long duration pigeon pea ecosystem in Bundelkhand region of Uttar Pradesh" was conducted at the Student Research Farm, BUAT, Banda, India during kharif 2021-22 and 2022-23. Seasonal occurrence of pod bug in pigeon pea exhibited that the peak population of pod bug (7.90/plant) at 10th standard meteorological week (SMW) during 2021-22 while during 2022-23 peak population of pod bug was recorded at 9th SMW (11.40/plant). The average population of C. gibbosa of both years was recorded during 9th SMW (9.38/plant). Correlation studies of the average number of pod bugs in both years and weather variables found that the morning relative humidity was negatively associated (r = -0.568), whereas evening relative humidity had a substantial negative correlation value (r = -0.665). The regression analysis found that maximum temperature, morning relative humidity, evening relative humidity, and wind velocity were the most influential factors on the occurrence of pod bug populations, influencing 16.3, 32.2, 44.2, and 20.7%, respectively.
