| Abstract | We characterized individual morphological types of the rose sawfly, Arge ochropus (Gmelin) (Hymenoptera: Argidae), hemocytes for the first time by means of light and differential interference contrast microscopy and scanning and transmission electron microscopy. Four types of hemocytes were identified in the hemolymph of larvae and pupae of A. ochropus: prohemocytes, plasmatocytes, granulocytes, and oenocytoids. Prohemocytes are the smallest type of hemocytes, rounded to ovoid cells with large nuclei. Plasmatocytes are polymorphic and variable in size. Granulocytes are oval and spherical cells variable in size, with variable number of rough endoplasmic reticulum, mitochondria, and microtubules in the cytoplasm. Oenocytoids contain eccentric nucleus and cytoplasm with small mitochondria and few rough endoplasmic reticula. Differential hemocyte counts indicated that plasmatocytes are the most abundant hemocyte type during early instars while granulocytes are the most abundant hemocyte type in the last instar. The pattern of total hemocyte count changed during rose sawfly development and reached its peak in prepupae and then declined slowly in the pupal stage. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
