| phylogenetic relationships between flies of the tephritinae subfamily (diptera, tephritidae) and their symbiotic bacteria. | the tephritinae is considered the most specialized subfamily of fruit flies, predominantly infesting flowerheads of asteraceae. some species are known to host specific non-culturable symbiont bacteria ("candidatus stammerula spp.") in the midgut. in this work we (i) examined the phylogenetic relationships among the insect hosts, (ii) investigated the presence of bacteria in other hitherto unexamined species, and (iii) evaluated the phylogenetic congruence between insects and symbionts. a total o ... | 2010 | 20171292 |
| presence of specific symbiotic bacteria in flies of the subfamily tephritinae (diptera tephritidae) and their phylogenetic relationships: proposal of 'candidatus stammerula tephritidis'. | the presence of symbiotic bacteria in flies belonging to the subfamily tephritinae, which predominantly infest the flower heads of composite flowers (asteraceae), was investigated. twenty-five species of flies, collected mainly in northern italy, were examined. the bacteria adhered to the midgut epithelium in a space external to the peritrophic membrane and therefore not in direct contact with the gut contents. specific, unique and live, but unculturable bacteria were consistently found in the m ... | 2008 | 18523165 |
