Transmission potential of the human head louse, Pediculus capitis (Anoplura: Pediculidae)
International Journal of Dermatology, 2004AbstractBackground Millions of people are infested by head lice every year. However, louse transfer between hosts is not well‐understood. Our goals were to determine: (1) which stages were most likely to disperse and why, (2) the likelihood of fomites transmission, and (3) if host blood gender affects louse development.Methods Various life stages of ...

Histochemical Analysis of the Nit of Pediculus humanus capitis (Anoplura: Pediculidae)
Journal of Medical Entomology, 1999Histochemical stainings of head louse nits were performed and observations indicated that the nit sheath was nonchitinous. One discernable membrane composed of hyaluronic acid was established that encircled the larvae within the egg. The structural framework of the egg included a definite lattice around each aeropyle of the operculum, through which ...

Permethrin-Resistant Head Lice (Anoplura: Pediculidae) in Argentina Are Susceptible to Spinosad
Journal of Medical Entomology, 2006The insecticidal activity of spinosad was evaluated against susceptible and permethrin-resistant human lice. In a permethrin-susceptible strain of the body louse, Pediculus humanus humanus L. (Anoplura: Pediculidae), the toxicity of spinosad was similar to that established for permethrin, with an LD50 value of 1.2 ng/insect and 2.4 ng/insect ...

Systemic Activity of Ivermectin on the Human Body Louse (Anoplura: Pediculidae)
Journal of Medical Entomology, 1990Eighty-one to 100% of nymphs and females of the human body louse (Pediculus humanus humanus) that fed artificially on blood containing 2.5-10 ng ivermectin/ml died. The mortality of nymphs and female lice fed on rabbits treated with 200 micrograms/kg ivermectin was very high during the first two to three days, then declined sharply, reaching the level ...

Pediculosis capitis is a prevalent and highly communicable condition infesting millions of elementary school students annually. Topical insecticides are the present standard treatment for this condition. Because resistance of head lice to insecticides is a growing concern, assessment of efficacy of pediculicidal and ovicidal activity of the various ...

Arrestant Effect of Human Scalp Components on Head Louse (Phthiraptera: Pediculidae) Behavior
Journal of Medical Entomology, 2016Relevant evidence has shown that parasites process host-related information using chemical, visual, tactile, or auditory cues. However, the cues that are involved in the host-parasite interaction between Pediculus humanus capitis (De Geer 1767) and humans have not been identified yet. In this work, we studied the effect of human scalp components on the

Pediculosis affects more elementary school students than all other communicable childhood diseases combined, excluding the common cold. The current study using scanning electron microscopy visualized operculums through which developing embryos received oxygen, as well as fracture lines within the adherent sheath by which the egg is attached to the hair.

The susceptibility of local head lice to permethrin, sumithrin, deltamethrin, and carbaryl was determined by laboratory bioassays in field-collected colonies. Head lice collected from the infested heads of children 6-12 yr old were tested within 3 h of collection. The longest survival of control insects in the laboratory was obtained by keeping them in
