Data shown are a compilation from the four assays. Feeding rates were scored on day 1 of the assay, immediately following removal of the feeding devices from the hens. Oviposition and mortality were scored on day 7. Data were analyzed statistically to compare results between mites fed on vaccinated and control hens by GLMM (F = 6.06, p = 0.014, gL1 = 1, gL2 = 747). Fed mites = total of fully engorged adult female mites recovered. Unfed mites = total unfed adult female mites were counted after 3 h placed on the hen. Fed reduction = 1–(Average Feeding Deg-AKR/Average Feeding Control)] × 100. Eggs = total accumulative count of eggs laid at day 7. Oviposition = eggs laid/number fed adult female mites. Oviposition reduction = [1–(Average Oviposition Deg-AKR/Average Oviposition Control)] × 100. GLMM: F = 6.060, p = 0.014. Dead mites = total number of fed adult female mites which shows no response to stimuli and looks dehydrated at day 7. Mortality = dead mites/number fed adult female mites. Mortality effect = [1–(Average Mortality Deg-AKR/Average Mortality Control)] × 100.
