Fig 3. Motility measurement following deltamethrin exposure in concentration- and time-dependent manner for An. Gambiae susceptible (G3) and resistant (Tiassale) strains as well as for Ae. Aegypti susceptible (New Orleans) and resistant (Cayman) strains.
The normalized movement index, which is the movement index (see Methods) divided by the index recorded before the application of insecticide, is plotted against the concentration after 60 min applications (A) and the time following exposure (B) to 10−6 M deltamethrin. Increased rate of movement inhibition is apparent in the larvae from adult susceptible strains (blue: G3 (G), New Orleans (N)) as compared to the adult resistant strains (red: Tiassale (T), Cayman (C)). The dotted line indicates the value before insecticide application. Error bars indicate ± 1 s.e.m.
