LIFE CYCLE OF SMALL SALMON ARAB COLOTIS AMATA (LEPIDOPTERA: PIERIDAE)

Abstract

This work highlights the complete life cycle of Colotis amata Fabricius (Lepidoptera: Pieridae). It lays eggs singly on tender leafs of Salvadora persica. The life cycle from egg to adult emergence is relatively short and spanning over 19-26 days. Observations regarding, egg laying, egg hatcing, larval period, pupal period and adult emergence was recorded along with the stage specific life table. The time required for the egg to develop to the adult was 19 - 26 days (egg 3 - 4; larva 10 - 15; pupa 6 - 7). Maximum indispensable mortality (6.72) was encountered at early larval stage as compared to other stages. Data for K-value exhibited the highest value (0.06) at early larval stage.
