Biıonomics of walnut pest, Chaetoprocta odata (Hewitson, 1865) (Lepidoptera: Lycaenidae) under laboratory conditions

Abstract : Chaetoprocata odata (Hewitson, 1865) is one of the economical important pest found on walnut trees. It is a serious leaf defoliator feeding on parenchymatous tissues of the new leaflets. The life history of the pest was observed under laboratory conditions. Eggs were laid in masses and on an average of 20.33 (±2.51) eggs were laid by female. Three larval instars were observed and mean duration of all the three larval instars was found 35.93 days. Larval feeding activity was observed increasing with each developing stage. Pupation was witnessed on hidden leaves and lasted for 18.5 days on an average. At the time of emergence of adults, the pupal colouration gets lighter. Females showed more longevity in the present experiment with an average of 22.33 (±3.05) days compared to males with 18.66 (±3.21) days.
