Studies on the vectors of leishmaniasis in Kenya: phlebotomine sandflies of Sandai location, Baringo district.

Adults of phlebotomine sandflies were collected from natural and man-made habitats in Sandai area of Baringo district using sticky and CDC light traps. Three sandfly species belongings to the Phlebotomus genus and eight species belonging to the Sergentomyia genus were recorded in the area. These flies fall into "perennial" group as they appeared to breed throughout the year.

Effects of permethrin-treated screens on phlebotomine sand flies, with reference to Phlebotomus martini (Diptera: Psychodidae).

Effects of permethrin-treated screens on the sand fly, Phlebotomus martini Parrot, a vector of visceral leishmaniasis in Kenya, were evaluated after the eighth treatment. Screens treated with 0.50 g/m2 of permethrin 20% emulsifiable concentrate were fitted inside houses and re-treated every 6 mo from August 1989 to December 1993.

Cutaneous leishmaniasis in Kenya: Sergentomyia garnhami (Diptera Psychodidae), a possible vector of Leishmania major in Kitui District: a new focus of the disease.

Investigations on phlebotomine sandflies in Tseikuru, Kitui District, Kenya were carried out to determine the vectors of Leishmania major. Sandflies were trapped from animal burrows over a period of one year using castor oil-smeared sticky traps. Nineteen phlebotomine sandfly species were identified and their prevalence in this habitat determined.

A bioassay to evaluate the efficacy of permethrin-impregnated screens used against phlebotomine sandflies (Diptera: Psychodidae) in Baringo District of Kenya.

Control of phlebotomine sandflies remains a difficult problem throughout the world because of the insects' very highly specialized breeding sites. Use of insecticides remains one effective methods for managing sandflies. The present studies were conducted to establish how long permethrin impregnated wall cloth remains effective against sandflies.

Evaluation of the residual efficacy of permethrin-impregnated screens used against mosquitoes in Marigat, Baringo district, Kenya.

Insecticide-impregnated screens and bednets are gradually finding wider use in malaria control programmes. The efficacy of these devices is dependent on the method of application, the acceptability by the people and effectiveness of the insecticide used. The present studies were carried out to determine the duration of the effectiveness of a permethrin-impregnated wall cloth (Mbu cloth) used in the Marigat area of Baringo District, Kenya in order to ensure its effective use.
