Blood intake of fourth instar nymphs from the saline injected group (control), β-lactamase gene double-stranded RNA (dsRNA) injected group (BLA) and brasiliensin dsRNA injected group (Brasiliensin) after one (columns 1-3) or two (columns 4-6) injections. The nymphs were allowed to feed on hamsters 48 h after the final injection. Asterisks indicate groups with significant statistical differences (P < 0.05). Results are represented as the average ± standard error.
