Abstract
Arthropod sampling via periodic direct bird examination and regular light trapping was conducted between June 2000 and October 2002 to survey for potential vectors of
Haemoproteus lophortyx to nonnative, captive-raised bobwhite quail (
Colinus virginianus) in northern California, USA. Examination of individual bobwhite quail (from 5 weeks of age through adult, total
n
=
76) was conducted on several dates during the transmission period (June–October). No ectoparasites, including hippoboscid flies (reported as
Haemoproteus vectors to wild quail in early literature), were collected from the birds. Trapping with ultraviolet light suction traps near the quail revealed nine species of biting midges (
Culicoides spp.). Of these, 94% were
C. bottimeri, which was abundant near the birds, and 65% of collected
C. bottimeri were engorged with blood.
C. bottimeri adult activity began in late-April, slightly before the onset of disease in the quail. Activity peaked between July and late-September, coincident with maximum reported transmission, and adult activity ceased by early-November. Nonengorged
C. bottimeri had a parity rate of 43.6% overall, suggesting excellent survival for biological transmission of a pathogen like
H. lophortyx. A controlled study was done injecting a macerated slurry of pooled, nonengorged, wild-caught
C. bottimeri into the peritoneum of 1-day-old bobwhite quail hatchlings held in insect-proof containers. Blood smears 13–19 days later confirmed
H. lophortyx infection in zero controls but all insect-injected quail. Biting midges, especially
C. bottimeri, transmit
H. lophortyx to captive quail and probably are the dominant vector to native California quail (
Callipepla californica) as well.
