Table 1 Percent repellency of Phlebotomus perniciosus 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)

  1. *Significant difference between the population means of the treated and control groups (p < 0.05).
  2. Right column gives the % repellency based on geometric means obtained for each dog, pooling the two experiments, it is not the simple mean of the two % of repellency calculated for each experiment.
