| the olive fly endosymbiont, "candidatus erwinia dacicola," switches from an intracellular existence to an extracellular existence during host insect development. | as polyphagous, holometabolous insects, tephritid fruit flies (diptera: tephritidae) provide a unique habitat for endosymbiotic bacteria, especially those microbes associated with the digestive system. here we examine the endosymbiont of the olive fly [bactrocera oleae (rossi) (diptera: tephritidae)], a tephritid of great economic importance. "candidatus erwinia dacicola" was found in the digestive systems of all life stages of wild olive flies from the southwestern united states. pcr and micros ... | 2009 | 19767463 |
