Pigeonpea (Cajanus cajan
) (L.) Millsp. is a tropical and subtropical species. Weather and pod borer complex is very important in the realization of potential yield. The present study was conducted during kharif
2020-21, at the Agriculture Research Farm of Birsa Agricultural University, Ranchi, Jharkhand.
The correlation coefficient revealed that maximum temperature (r=-0.72**), minimum temperature (r=-0.80**) and mean temperature (r=-0.76**) influenced the population of pod borer complex negatively, while the other abiotic factors were non-significant, with the exception of relative humidity at 7 am (r= 0.31), mean RH (r= 0.71) and HTI (r= 0.69 **), which showed a positive correlation with pod borer larval populations. Population dynamics of pod borer complex revealed that peak of the larval population was found on 1st standard week.
