We previously examined the physiological role of the anticoagulant salivary protein 14 () in adult and showed that Salp14 played a role in tick feeding and engorgement. We now analyze whether the disruption of the family expression by RNA interference affects tick weight in naïve nymph expression after dsRNA injection was significantly reduced, as shown by mRNA and protein analysis. However, nymph engorgement weight was not altered in ( paralog) dsRNA-injected ticks. We also determined and acquisition in nymphs that had reduced Salp14 expression. and acquisition was not affected 72 hours after feeding. Our results suggest that different mechanisms govern nymph and adult feeding in .
