Efficacy of either orally administered fluralaner or topically administered imidacloprid/flumethrin for controlling Rhipicephalus sanguineus sensu lato premises infestations

Table 1 Outcomes for engorged ticks (larvae, nymphs, or adult females) placed within ecdysis monitoring tubes in a different kennel at each tick release day and observed every 3–4 days for molting, oviposition, larval hatching or unfed tick survival

^aDeath of first and last specimen within each tube
^bPre-hatch period—the days between tube placement containing engorged females and the first hatched larvae appearance
^cFew unfed adults were alive on day 84; therefore, the maximum survival of these unfed adults was higher than the maximum value here
