| patterns of inner chorion structure in anastrepha (diptera: tephritidae) eggs. | the inner chorion structure of anastrepha eggs from 16 species of various infrageneric taxonomic groups is described by scanning and transmission electron microscopy. the layers of the chorion, the outer egg membrane, are structurally similar. furthermore, an additional trabecular layer (atl) that exists in some species, together with other characteristics, facilitates the recognition of four patterns of chorion structuring: pattern i, in which the atl layer is absent, is found in anastrepha ami ... | 2017 | 27847335 |
