Abstract

The present study was conducted to study the population dynamics of spotted pod borer, Maruca vitrata Fab. in vegetable cowpea for two consecutive seasons viz., summer and kharif 2021. The highest number of larval population was recorded during 15th Standard Meteorological Week (SMW) in summer 2021 and 36th Standard Meteorological Week (SMW) in kharif 2021, coinciding with the peak flowering stage (days to 50% flowering) of vegetable cowpea. The results indicate the key pest the population dynamics and seasonal abundance status of this pod borer species in the region.

Keywords

Maruca vitrata, population dynamics, seasonal abundance, vegetable cowpea

Conclusion

An analysis of the population dynamics of M. vitrata, considering the phenology of crop development, will provide information on the specific time when the presence of this species is at its highest and when its activity is at its lowest. This data may be utilised to modify the duration of agricultural cultivation, determine the optimal dates for planting, and implement plant protection strategies to control insect populations. The highest occurrence of M. vitrata was recorded during the period of peak flowering and pod formation stage.
