Recent developments in methods of mosquito control

摘要

Since residual insecticide spraying in domiciles does not sufficiently control some species of anophelines to halt malaria transmission, alternate methods of control have been investigated. These include ultra-low-volume (ULV) sprays or aerosols, the release of sterile males to suppress or eradicate populations, and the use of diseases or parasites to interfere with transmission or to reduce populations of mosquitos. The ULV aerial sprays gave practical control of Anopheles albimanus in Haiti and interrupted malaria transmission. The release of sterile males almost eliminated an isolated population of A. albimanus in a small valley in El Salvador. Studies are in progress to evaluate the effect on field populations of anophelines of a protozoan disease and two nematode parasites.
