Identification of Sodium Channel Mutations in Human Head Louse (Anoplura: Pediculidae) from Denmark [PDF]
Journal of Medical Entomology, 2005 The presence of the two mutations T9291-L932F in the voltage-sensitive sodium channel gene associated with permethrin resistance (kdr-like) was shown in head louse, Pediculus humanus capitis De Geer, populations in Denmark. The existence of one susceptible and one T929I-L932F haplotype based on the limited single nucleotide polymorphism (SNP) of these ...

Geographical Distribution of Pyrethroid Resistance Allele Frequency in Head Lice (Phthiraptera: Pediculidae) From Argentina [PDF]
Journal of Medical Entomology, 2014 The human head louse, Pediculus humanus capitis De Geer (Phthiraptera: Pediculidae), is an obligate ectoparasite that causes pediculosis capitis and has parasitized humans since the beginning of humankind. Head louse infestations are widespread throughout the world and have been increasing since the early 1990s partially because of ineffective ...

Parasitology Research, 2014 Head lice lay eggs in human head hairs in order to reproduce. There is a difficulty associated to the process of detaching these eggs: they are tightly gripped to the hair by a secretion produced by female head lice. The physical removal of eggs has become an important part of treatment of louse infestations.
