Seasonal incidence of spotted pod borer [Maruca vitrata (Geyer)] on green gram [Vigna radiata (L.) Wilczek]

The present investigation was conducted at the research plot of the Department of Entomology at Central Research Farm (CRF), Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, during the Kharif season of 2024-25. The incidence of spotted pod borer Maruca vitrata In greengram was appeared during 35th SMW (1.55) and remained active till the 40th SMW the peak activity was observed on 38th SMW (4.07) larvae/ten plant. The population of spotted pod borer showed significant positive correlation with maximum temperature (r = 0.61*) and minimum temperatures showed positive but non-significant correlations (r = 0.24NS). Regarding humidity, both maximum and minimum humidity levels displayed non-significant positive correlation(r = 0.05NS and r = 0.12NS respectively). Rainfall exhibited a non-significant negative correlation (r = -0.11NS).
