| histological comparisons of parasitism by schistonchus spp. (nemata: aphelenchoididae) in neotropical ficus spp. | syconia (enclosed infructescences) infested with host-specific species of schistonchus (aphelenchoididae) were collected from six species of ficus (moraceae) native to florida or panama. they were sectioned and histologically examined to assess the effects of parasitism. parasitism by schistonchus spp. was associated with hypertrophied cells, tissue necrosis, and the presence of an exudate in all species. occasional hypertrophy of the outer epidermal cells occurred on seed florets, wasp florets, ... | 1999 | 19270912 |
