Abstract
To quantify the effect ofNosema algerae (Microsporida, Nosematidae) on the development ofPlasmodium falciparum inAnopheles stephensi (Diptera, Culicidae), we carried out infection experiments under standardized laboratory conditions. Apart from a mean reduction of 69% in oocyst development, smaller numbers of oocysts and fewer sporozoites were found in theNosema-infected mosquitoes. In addition, nosematosis resulted in higher mortality. The potential role ofNosema algerae as a biological control agent is discussed.
