An outbreak of pediculosis at primary schools was recorded in the Czech Republic in 1992.
Almost 20% of children in some schools were intested.
This outbreak can be attributed to the resistance of head lice to permethrin, which has not been mentioned in literature yet.
The resistance factors established in three towns range between 2 and 385 and between 5 and 557 for LC50 and LC90 values, respectively.
This resistance has developed after exclusive use of pyrethroids lotion and shampoo in the Czech Republic since 1978, and it was accompanied by a cross-resistance to d-phenothrin and bioalethrin.
But the susceptibility of head lice to malathion and pirimiphos-méthyl in 1992 was very similar to that found in 1981.
The lotion containing 0.3% and 0.7% of primiphos-méthyl respectively were found to be effective as well.
