Table 2 Percent insecticidal efficacy against Phlebotomus perniciosus observed at 4 h in dogs treated with the combination of fipronil and permethrin (Experiments A & B) based on Geometric means

From: Repellent and insecticidal efficacy of a new combination of fipronil and permethrin against the main vector of canine leishmaniosis in Europe (Phlebotomus perniciosus)

  2. Right column gives the % insecticidal activity based on geometric means obtained for each dog, pooling the two experiments, it is not the simple mean of the two % of insecticidal activity calculated for each experiment.
