Infection is also prevented by controlling the breeding cycle of the vector, which should significantly reduce the number of cases and rate of parasite infection. Larval control is important by limiting breeding sites. Biological control using Bacillus thuringiensis toxin is widely used as a larvicide for mosquito larvae. Methoprene kills the larvae, and also the introduction of fish which eat the larvae, into the breeding grounds, is important. These approaches are generally considered to be environmentally friendly methods of mosquito control.

Besides the insecticidal activity of AgNPs on an insect, Bt has great insecticidal effects on insects by producing endospores and a poisonous parasporal crystal. After the Bt was ingested by insects, dissolved in the alkaline insects’ midgut, leading to the releasing of a delta-endotoxin that activated by midgut proteases. Once activated, the delta-endotoxin interacts with larval midgut epithelial cells and destroys the membrane leading to the death of insects (Gill et al. 1992; Bravo et al. 2007; Bravo et al. 2011).
