Abstract

Five types of haemocytes were identified in Poecilocerus pictus (Fab.) and their ultrastructural details and differential counts were studied. The types identified are the prohaemocyte, plasmatocyte, granular haemocyte, oenocytoid and coagulocyte. In response to the injection of yeast cells into the haemocoel, changes in haemocyte morphology and differential counts occurred. The predominant cell involved in phagocytosis is the plasmatocyte, followed by granular haemocyte.

Résumé

Clinque éspéces des hemocites ont été identifeiée en Poecilocerus pictus (Fab.) et leur détails ultrastructural et comptes différentielle ont été étudiés. Les espèces identifiées sont prohemocite, plasmatocite, granulocite, oenocitoid et coagulocite. Par suite d'injection de suspension cellulaire de la levure dans le haemocoel, la morphologie des ces celluss a été modifiées et les conptes différentielle ont été variées. Le rôle prédominant est joué par plasmatocites suivre par granulocites dans le processus de phagocitosis pour le mécanism de défence.
