Eugenol-hyperactivated nymphs of Triatoma infestans become intoxicated faster than non-hyperactivated nymphs when exposed to a permethrin-treated surface

Table 2 Knockdown time 50% (KT50) for permethrin in T. infestans nymphs exposed simultaneously to eugenol vapor

Simultaneous exposure to:	KT50 (min)	95% CI	Slope ± SE
Acetone	51.90^a	46.9–56.7	8.70 ± 1.39
Eugenol (33 μg/cm²)	39.50^b	34.9–44.8	6.30 ± 0.89

Abbreviations: KT50, knockdown time 50%; 95% CI, 95% confidence interval
Notes: Permethrin was applied as a film on filter paper (1840 mg/m²). KT50 values followed by different letters are significantly different (based on their respective 95% CI not overlapping; P < 0.05)
