abstract
Studies on succession and incidence of pod borers on Indian bean, Lablab purpureus var. typicus (L.) Sweet were carried out to savvy the knowledge regarding influence of weather parameters on pest appearance. The spotted pod borer, Maruca vitrata (Geyer) and gram pod borer, Helicoverpa armigera (Hubner) were found to infest the crop with varying intensities during Kharif, 2019. The incidence of spotted pod borer and gram pod borer started in second week of August (33^rd SMW). The peak population of spotted pod borer, M. vitrata (9.80 larvae/ five plants) was recorded in the second week of September (37^th SMW), gram pod borer, H. armigera (7.90 larvae/ five plants) in the third week of September (38^th SMW). The minimum temperature showed a positive significant correlation with population of both spotted pod borer and gram pod borer (r= 0.87 and 0.81 respectively). The other meteorological parameters, viz., maximum temperature, relative humidity and rainfall had non-significant correlation with population of the two pod borers.
