Ultrastructure of the ovary of Dermatobia hominis (Diptera: Cuterebridae): III. Gonial cell degeneration [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 1992
We studied the ultrastructural aspects of pre-pupae and pupae ovaries of Dermatobia hominis. Physiological degeneration of gonial cells was observed: (a) after the ovarioles differentiation, in the oogonia residing in the apical region of the ovary; (b ...

Defense reactions of Dermatobia hominis (Diptera: Cuterebridae) larval hemocytes [PDF]

open access: yesBIOCELL, 2003
The defense reactions against biological (Histoplasma capsulatum and Escherichia coli) and non-biological materials (China ink and nylon thread) were tested in vivo in third instar larvae of Dermatobia hominis. The cellular defense performed by larval hemocytes was observed under electron microscopy.
