Resumen:
The use of pyrethroids to control head louse infestations have suffered
considerable loss of efficacy due to the development
of resistance. In the last past years, several new
alternative products to synthetic pyrethroids have been developed and
are
sold in the Argentinean market against head lice. The
present study investigated the efficacy of two new Argentinean products
Nopucid Qubit® and Nopucid Bio Citrus® and its comparison
with two reference products Nyda® and Hedrin®. Nopucid Qubit® is
a two-phase lotion containing geraniol and citronellol
(phase 1) and ciclopentaxiloxane (phase 2); while Nopucid Bio Citrus®
contains dimethicone, ciclopentaxiloxane, and bergamot
essential oil. These products are physically acting compounds. The
sensitivity of two laboratory assays for testing insecticide
activity of new formulations was also compared. Mortality (100%)
of motile forms occurred after they were exposed to any
product for 1 and 2 min, either by in vitro or ex vivo test. Concerning
ovicidal activity, the most effective pediculicides were
Nopucid Bio Citrus® and Nyda®, followed by Hedrin® and Nopucid Qubit®.
The present study revealed, for the first time, the efficacy
of over-the-counter commercial pediculicides available in Argentine
(Nopucid Bio Citrus® and Nopucid Qubit®) on either motile
stages or eggs against head lice.
