Fig. 5From: Eugenol-hyperactivated nymphs of Triatoma infestans become intoxicated faster than non-hyperactivated nymphs when exposed to a permethrin-treated surfacePermethrin picked-up by hyperactivated T. infestans from an impregnated filter paper. Nymphs were topically pre-treated with acetone alone (empty bar) or a solution of eugenol in acetone (filled bar), then exposed to a filter paper treated with permethrin (1840 mg/m2). Each bar represents the mean of five independent replicates. Vertical lines represent the SE. Bars marked with different letters are significantly different (Student’s t-test, P < 0.05)Back to article page
