Escape responses of <i>Aedes aegypti</i>¹ to different concentrations and coverage of alphacypermethrin under laboratory conditions.

1Four to seven day-old females, non-blood-fed, 24 hour sugar starved (PERU). 2For each trial (n = 6 replicates). 3Surface area coverage (SAC) of treated material. 4For each trial percentage escaping after correction based on escape in the control and knockdown in the metal test chambers using Abbott's formula. Means in the same column followed by the same letter were not significantly different. Multiple comparisons of means were done using Scheffe's test (α = 0.05). 5P values are from Wilcoxon 2-sample test for difference between the number escaping in a chemical treatment chamber and an acetone treatment (control) chamber. 6P values are from t-test examining the effect of treatment concentrations on corrected percentage escaping at each treatment coverage. 7WHO recommended field application rate (FAR) = 7.2 nm/cm2 or 0.03 g/m2. 8P values are from one-way ANOVA examining the effect of treatment coverage on corrected percentage escaping at each treatment concentration.
