Comparative-Study Of Ddt, Carbaryl (Sevin) And Actellic (Pirimiphos-Methyl) In The Treatment Of Pediculus-Humanus-Capitis Infestation

A survey of school children from poor socio-economic background in Kuala Lumpur,Malaysia showed that Pediculus humanus capitis infestation is much more widespread than otherwise realized. Three insecticides, DDT; Actellic, and Sevin, were tested as pediculicides on 2441 primary school children. Treatment with sevin and actellic at 0·5 and 0·4% concentration, respectively, gave a success rate of 100% against adults and nymphs of Pediculus humanus capitis . DDT at a 5% concentration gave a cure rate of 51·3%. The ovicidal and reinfestation rates are also discussed. No adverse side effects were reported from those treated with actellic and sevin.
