Prophage strains used in this study.

Wp-Wolbachia pipientis; Rp- reproductive parasitism; CI – cytoplasmic incompatibility; NA – not applicable; Bp – Baseplate; Vir. – Virulence; Rec. – Recombinase; Rep. – Replication; Unchar. – Uncharacterized. WOVitA3 was not analyzed because the initial identification via PCR product published in [45] was found to be a chimera. For the purposes of this study, WOMelB1 and WOMelB2 are combined into one haplotype, WOMelB; see text for justification. Similarly, WORiA-1 and WOiRA-2 are analyzed as one haplotype, WORiA, since they are identical copies.
