An investigation was carried out during 2015-16 to evaluate different bins and bags as storage structures for groundnut
pods against infestation by Caryedon serratus. The data was recorded upto six months at 15 days interval. Oviposition preference, adult emergence and per cent pod damage by count observed was least in magic cover followed plastic bin and triple layered polythene bag. The per cent pod damage by weight recorded was lowest in plastic bin followed by magic cover and triple layered polythene bag. Whereas, per cent weight loss recorded was least in magic cover followed by triple layered polythene bag and plastic bin. All the biological parameters viz., oviposition, adult emergence, per cent pod damage by count and weight and per cent weight loss due to C. serratus were noticed maximum in cloth bag and earthen pot
KEY WORDS: Caryedon serratus, storage bins and storage bags, oviposition, adult emergence, per cent pod damage, per cent weight loss.
