In conclusion, we think obligatory
Wolbachia
symbiosis in insects may represent a ÑslaveryÒ
association, where the bacteria, for their own advantage, have captured their host. In this sense, as
considered for the other reproductive alterations induced by
Wolbachia
, obligatory
Wolbachia
could
also be qualiÝed as parasites that have manipulated host reproduction to the point of rendering the
host incapable of independence. These new cases of reproductive parasitism could therefore be
qualiÝed as Ñobligatory parasitism.Ò
