Pediculus humanus capitis: an update
Head lice infestation, or pediculosis capitis, caused by Pediculus humanus capitis, is a common health concern. In the US, where pediculosis capitis is the most prevalent parasitic infestation of children, 6 to 12 million people are affected every year. Pediculosis capitis remains confined to the scalp. Scalp pruritus is the cardinal symptom, although patients with lice can be asymptomatic. Pru...
متن کاملLaboratory studies of susceptibility and resistance to insecticides in Pediculus capitis (Anoplura; Pediculidae).
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 the dark at 18 degrees C and 70-80% RH. Th...
متن کاملIsoenzymes of human lice: pediculus humanus and P. capitis.
Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.S.A.) and the head louse (P. capitis DeGeer from France, Madagascar, Mali & Senegal) were compared. Only esterase two e...
متن کاملEsterase-mediated malathion resistance in the human head louse, Pediculus capitis (Anoplura: Pediculidae)
Resistance in a dual malathionand permethrin-resistant head louse strain (BR-HL) was studied. BR-HL was 3.6and 3.7-fold more resistant to malathion and permethrin, respectively, compared to insecticide-susceptible EC-HL. S,S,S-Tributylphosphorotrithioate synergized malathion toxicity by 2.1-fold but not permethrin toxicity in BR-HL. Piperonyl butoxide did not synergize malathion or permethrin t...
