Abstract:
Diamond back moth (Plutella xylostella (Linn.)) (Lepidoptera: Plutellidae) is one of the major constraints for profitable cultivation of cabbage (Brassica oleracea var. capitata Linn.). Since the biology of an insect pest differs in different regions based on the weather factors of the particular area, the sufficient knowledge about the biology of an insect pest is necessary for adopting suitable control measures in a particular region. Almost no systematic works have been done on this aspect in Manipur. Therefore, the investigation of biology of diamond back moth is carried out on cabbage var. ‘Pride of India’ under Imphal agro-ecological situations during Rabi season of 2014-15. Based on the laboratory study conducted different biological aspects of DBM is discussed briefly in this paper.
