Comparative trial demonstrates lower mite infestation in Rous sarcoma regressor lines, suggesting inherited resistance from Jungle Fowl.

To evaluate genetic resistance to the northern fowl mite among Arkansas Rous sarcoma regressor and progressor lines alongside Giant Jungle Fowl.
Arkansas regressor lines (B1B1R, B2B2R, B3B3R), progressor lines (B1B1Pr, B2B2Pr, B3B3Pr), and Giant Jungle Fowl were simultaneously infested with northern fowl mites at 28 weeks of age.
Chickens were housed in similar environments, and mite ratings were scored weekly across a 5-month follow-up duration.
No evaluated chicken strains exhibited complete resistance to northern fowl mites.
Mite infestation differed significantly among strains (P <= 0.05), with regressor lines demonstrating significantly lower infestation rates than progressor lines in both males and females (P <= 0.05).

Devaney et al. (1982) studied this question.
