Haemoproteus - Effect On Vectors

Effect On Vectors

H. columbae infects rock pigeons (Columba livia) and is vectored by a hippoboscid fly (Pseudolynchia canariensis). Both sexes of vector can transmit the parasite. Species of the Hippoboscoidea the superfamily to which Ps. canariensis belongs do not lay eggs. Instead the larvae hatch in utero, are fed internally by 'milk glands' and pass through three morphological stages before being deposited to pupate. The survival of female flies is significantly reduced when they were infected with the parasite. In contrast no effect is seen on male fly survival. Additionally the females produce fewer offspring when infected but the quality of the offspring does not seem to be affected.
