Figure 4From: The synergistic action of imidacloprid and flumethrin and their release kinetics from collars applied for ectoparasite control in dogs and catsDose response curves of flea mortality for flumethrin or imidacloprid or a 1: 1.85 combination of flumethrin and imidacloprid. The dose response curves show mean % mortality after 24 hours contact against Ctenocephalides felis on glass vial surfaces treated with different doses of flumethrin, imidacloprid or a 1: 1.85 combination of flumethrin and imidacloprid (mean data from 2 separate trials; curves including 95% confidence interval as dashed lines calculated with SigmaPlot for Windows 11.0 (Build 11.0.0.75, © 2008 Systat Software, Inc.).Back to article page
