Physiological index of ticks in the TβRI knockdown experiment.

Physiological index	untreated	ds TβRI	dsNC
recycle Ticks number	31	33	32
the number days of engorgement	10.78 ± 0.229	8.23 ± 0.384	11.69 ± 0.400
the weight after engorgement (g)	1.095 ± 0.0174	0.4044 ± 0.0270	1.098 ± 0.0190
the spawning rate	62.98%	39.02%	62.39%

Each data point is the mean ± SEM of three independent experiments (n = 3). Different letters on the same line indicate significant differences (P < 0.05).
