Studies the physiology of haemolymph innon-diapausing and diapausing generation of A. mylitta in its ontogenticstages. A. mylitta is a widelyexploited wild sericigenous insects, but little was known about itshaematological aspects. It was further noticed that A. mylitta shows a wide range of variation in haemocytes picture and haemolymph compositionin different insect species. Hence the need for this study.
