In vitro feeding of ticks
| Species | Life stage | Engorgement rate (%) | Engorgement weight (mg) | Duration of feeding (days) | Time until oviposition | Molting rate (%) |
|---|---|---|---|---|---|---|
| Ixodes ricinus | Adults | 49 ± 15 | 186.2 ± 61.8 | 14.5 ± 3.1 | 14.7 ± 4.9 daysa | – |
| Nymphs | ~ 50 | 3.0 ± 1.0 | 7.9 ± 1.8 | 10 ± 5 weeks | 92 | |
| Dermacentor margiatus | Adults | 29 | 414.6 ± 136.7 | 14.8 ± 3.4 | 4 daysb | – |
aDays until oviposition of I. ricinus were calculated from 15 egg-laying ticks
bIn the D. marginatus experiment, only 1 tick laid eggs after 4 days
