Abstract
A study was conducted to characterize stem and leaf gall tissues induced by Dryocosmus kuriphilus. Galls were collected from Qing Chinese chestnut trees growing in Mantua, Ohio on 3 May 2012 and prepared for light or transmission electron microscopy.
Uni-and multi-chambered galls had ovoid-shaped larval chambers containing one larva per chamber.
Damaged plant cells with broken cell walls and disorganized organelles in the cytoplasm were evident adjacent to the larval chambers.
A continuous layer of nutritive cells with hypertrophied nuclei and nucleoli, abundant lipid bodies and mitochondria, and fragmented vacuoles was visible.
At the outermost region of the nutritive tissue, cells had recently divided.
Vascular tissue within the gall cortex was connected with that of the plant host tissue.
