Ca. Erwinia dacicola
The close association between the olive flyBactrocera oleae(Rossi) (Diptera: Tephritidae) and bacteria has been known for more than a century. Recently, the presence of a host-specific, hereditary, unculturable symbiotic bacterium, designated ‘CandidatusErwinia dacicola’, has been described inside the cephalic organ of the fly, called the oesophageal bulb. In the present study, the 16S rRNA gene sequence variability of ‘Ca.E. dacicola’ was examined within and between 26 Italian olive fly populat
