Morphological and Immunological Characterization of Hemocytes in Larvae of Pentodon quadridens bidentulus (Famaire, 1887)

Dooseon Hwang, Young-Chul Jang, Saeyoull Cho


The purpose of this study was to analyze the characteristics of hemocytes in the hemolymph of the larvae of Pentodon quadridens bidentulus and the characteristics of the hemocytes responsible for cellular immunity during pathogen infection. Granulocytes, plasmatocytes, oenocytoids, spherulocytes, prohemocytes and adipohemocytes were found in the circulating hemocytes. Among them, granulocyte were observed as cells responsible for immunological phagocytosis during entry of foreign substances. In particular, it was observed that the most active phagocytic action occurred within 12 hours in vivo, and that after 24 hours, the immune activation was reduced and converted to a normal state. Plasmatocytes were occasionally observed as immunological response, but the remaining hemocytes were not related to immunological activation.
