Table 2. Phenotypic changes of ticks injected with a single or a combination of different dsRNA(s).

aSixteen ticks were collected from the host for the subsequent experiments at 4 days after attachment.bThese ratios show the fecundity of engorged females. Values are the means of ±SD.cThese mortality rates show the percentages of number of dead ticks 20 days after drop-off to the total number of engorged ticks per treatment.dHatchings from eggs to larvae were examined at 25°C in an incubator for 60 days.*P**Pluc dsRNA-injected group vs. HlSRB-, HlVgR-, HlVg-1-, HlSRB/HlVgR-, HlSRB/HlVg-1-, HlSRB/luc-, and luc/HlSRB dsRNA-injected groups.
