Efficacy of indoxacarb applied to cats against the adult cat flea, Ctenocephalides felis, flea eggs and adult flea emergence

Table 3 Geometric mean percent adult emergence, predicted adult emergence and percent efficacy relative to non-treated controls for predicted adult flea emergence from eggs collected from cats treated with a 19.5% w/v indoxacarb topical spot-on

¹ Each of 8 cats in the control group received no treatment. Each of 8 cats in the 19.5% w/v indoxacarb group were administered the topical spot-on according to label directions on Day 0.
² Each cat was infested with 50 adult Ctenocephalides felis from the KS1 strain on days -2, 7, 14, 21, 28, 35 & 42.
³ Days post-treatment that eggs were collected.
⁴ % Adult emergence = (# of adults emerging/# of eggs collected) × 100.
⁵ Predicted emergence = (% emergence × geometric mean # eggs collected from Table 2).
⁶ % Efficacy = ((predicted adult emergence control-predicted adult emergence treatment)/geometric mean % adult emergence control) × 100.
NE = no flea eggs collected.
