Resumen:
Abstract 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.
