Life stages of groundnut bruchid Caryedon serratus was studied in the laboratory of Seed Technology Research Unit, Dr Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2019-20. The bruchid was multiplied under laboratory conditions at 25± 2°C and 70% RH on groundnut pods. Egg, grub and pupal periods, adult longevity and total life period were examined. The mean life period of male groundnut bruchid was 69 days and for female it was 76.50 days. The grub (damaging stage) period lasted for 33 days.
