Fig. 2From: Speed of flea knockdown of spinosad compared to afoxolaner, and of spinosad through 28 days post-treatment in controlled laboratory studiesPercent effectiveness, 1 and 3 h post treatment (Day 0) and post infestation (Day 7). Spinosad, Afoxolaner. Percentages based on geometric mean live flea counts (normal fleas, excluding those showing abnormal movement) of each group compared to an untreated control group. Different from control: a p = 0.0045; c p = 0.0133; d p = 0.0001; g p < 0.0001; j p = 0.0220. Different from afoxolaner: b p = 0.0059; e p = 0.0009; f p = 0.0276; h p < 0.0001Back to article page
