New host record for Ornithomya variegata (Diptera: Hippoboscidae) in New Zealand with a review of previous records in Australasia

摘要: Among 22 fantails captured, 4 fantails were infected with louse flies (prevalence= 3.6%). The louse flies were found only on male fantails although similar number of males (N= 10) and females (N= 12) were examined. In 3 of 4 cases, only 1 lousefly per bird was recorded and 1 adult male fantail carried 2 louse-flies (average 1.25 flies per bird). Most of the louse flies were located on the abdomen and flank regions of the birds (Fig. 1). Flies were 4.7 to 5.6 mm in total length.This is the first report of O. variegata sp (Bigot, 1885) on the North Island subspecies of the New Zealand fantail and in the Family Rhipiduridae. This discovery represents also the lowest latitude of Ornithomya variegata distribution in New Zealand. Only 1 or 2 louse flies were observed per bird, but
