There is a large variety of over-the-counter anti-louse products, but their efficacy is not always well assessed. Our objective was to test the pediculicidal and ovicidal efficacy of 21 over-the-counter head louse(More)

After a recall of different existing kinds of louse, pediculicides and their mode of action, the authors report the bio-clinical trials they carried out in Antananarivo using different associations and galenic forms of medicines. The objectives of these studies on the treatment of scalp pediculosis is either the development of efficient insecticides or the(More)
The obligation to prove pediculicides efficacy is relatively recent. Two tests are required by the authorities to obtain registration. In vitro test (with Pediculus humanus humanus) is the first step to evaluate the efficacy of new molecules. It must be followed by bio-clinical tests (with infested children by Pediculus humanus capitis). For those tests the(More)
A monthly study of populations of Littorina saxatilis (mollusc, gasteropod) very strongly parasited has allowed to establish relations between the said mollusc and some parasite trematodes which live in it. A selection of animals was done in two stations of the Roscoff region (Finistere). A total of more than 1.000 individuals have been examined in each(More)
