THE NATURE OF CYSTS FOUND IN PUPAE AND ADULTS OF NEODIPRION SWAINEI
Published online by Cambridge University Press: 31 May 2012
Abstract
The cysts sometimes observed in the intestinal cavity of pupae and in the abdominal cavity of adults of Neodiprion swainei Midd. are not typical tumors. No cell proliferations were observed but rather a precipitation of the cells that accumulated and formed a membrane composed of many layers. The cysts appear to result from encapsulation of incompletely lysed or unlysed cells of the midgut epithelium. They are not necessarily the result of a viral infection.
