Nosema algerae (Nosematidae, Microsporida): laboratory infections of Anopheles larvae and prospects for field application.

Different larval instars of Anopheles arabiensis were infected experimentally using different dosages of Nosema algerae spores. The N. algerae infections killed most of the exposed larvae at the instar treated. Chronic infections in adults developing from treated larvae decreased fecundity and shortened the life of the adults. The possibility of applying N. algerae as a control agent against An. arabiensis larvae is discussed.
