Abstract: The experiment was undertaken to investigate the incidence of different species of white grub infesting groundnut. The appearance of various species of white grub beetles initiated in the 24^th week of 2023. Initially, two beetles were collected from a field-based light trap during this week. The beetle collection continued to rise consistently, reaching its peak during the first half of August, specifically in the 31^st week, where a total of 112 beetles were recorded. Starting from the 33^rd week, there was a decline in beetle collection from the light trap. By the 36^th week, only 6 beetles were observed. Subsequent observations in the 37^th week indicated fluctuating beetle numbers, with an increase to 9. These observations spanned from June to the first week of October, revealing that the highest beetle collections occurred in the months of July and August compared to other months.
