Abstract
An electron microscopical study on hemocytes of last instar larvae of Orthoptera (Acrida cinerea Thunberg, Paratenodera sinensis De Saussure, Atractomorpha lata Hotschulsk was performed to observe cell types, structures and their origins. Prohemocytes are the smallest round cells with large, nucleus, poorly developed cytoplasmic organelles and lower composition ratio, accouting for less than 1% of all cell types. Little remarked differences were revealed among different species. Plasmatocytes are relatively large cells with higher composition ratio, accounting for 5 to 20%. The majority of the plasmatocytes are oval forms with numerous external cytophismic projections., relatively well developed cytoplasmic organelles. Granular cells are characterized by various granules in cytoplasm. Some considerable remarked differences were revealed among different species. Furthermore the granules themselves differ in fine structures. Adipohemocytes were found only in Acrida cinerea Thunberg.
방아깨비, 사마귀, 섬서구메뚜기의 종령유충을 재료로 하여 전자현마경적 관찰을 하였다. Prohemocyte는 세포중 가장 작고 구성비도 낮으며 그 구조상 다른 혈구의 기원이 되는것 같다. Plasmatocyte는 나비류에서 와는 달리 그 형태가 대부분 난형이고 허족과 소기관을 가장 많이 가진다. Granular Cell은 종에 따라 그 형태가 뚜렷이 구분되며 어느 경우나 구성비는 높았다. 같은 세포의 과립이라 할지라도 그 미세구조가 몇 가지로 구분되고 이것은 아마도 축적단계에서 오는 결과인듯 하다. Adipohemocyte 는 방아깨비에서만 나타났고 구성비는 대단히 낮았다.
